(#886): Move NEWS.md back to NEWS

Calling it NEWS.md causes the release scripts for download.gnome.org
to be unable to find the release notes.  So, let's shave that yak
later.

Fixes #886.

+Version 2.55.0-alpha
+====================
+
+This is the first release in the new development series.
+
+- The Minimum Supported Rust Version (MSRV) is now Rust 1.58.
+
+- #855: The release tarball no longer contains vendored Rust
+  dependencies.  Most distributions now have infrastructure to pull
+  these themselves, so let's make the tarball smaller.
+
+- #880 - Accept patterns with userSpaceOnUse units for the stroke of
+  axis-aligned lines.
+
+- #706: Small reductions in memory consumption of the DOM tree
+  (Michael Howell).
+
+- Updates for the gtk-rs API (Bilal Elmoussaoui).
+
+Version 2.54.4
+==============
+
+- #817 - Support CSS Color 4 syntax for `<alpha-value>`.  Opacities
+  can be specified as numbers or percentages now, e.g. `0.5` or `50%`
+  (Michael Howell).
+
+- #870 - Roll back minimum required version of Pango to 1.46.0
+  (Kleis Auke Wolthuizen).
+
+- #867 - Fix Windows NMake install when documentation is not built.
+  (Peter Williams).
+
+Version 2.54.3
+==============
+
+- #866 - Fix detection of gi-docgen (David King, Jan Alexander Steffens).
+
+- Install the generated documentation in the correct place so that
+  Devhelp can find it (thanks to Jan Tojnar for pointing this out).
+
+Version 2.54.2
+==============
+
+- #823 - Fix regressions when computing element geometries.
+
+- Add a --disable-gtk-doc option for the configure script, so people
+  can disable generating documentation for cross-compiling (Matt
+  Turner).
+
+- MSVC: Support generating documentation, and passing introspection
+  paths (Chun-wei Fan)
+
+Version 2.54.1
+==============
+
+This release just has some build-time fixes.
+
+- Fix oversight in the Minimum Supported Rust Version (MSRV) - this
+  release requires Rust 1.56 or later.  This has been true since
+  librsvg 2.53.1, but it was not checked correctly. (Matt Turner)
+
+- #859 - Make rst2man and gi-docgen optional. (Kleis Auke Wolthuizen)
+
+- #856 - Fix documentation comments.
+
+Version 2.54.0
+==============
+
+This is a summary of the 2.53.x release notes; you can also read them
+for more detail.  Not many new features; we've been working on
+infrastructure and documentation.
+
+- Librsvg now supports SVG2 geometry properties for these elements:
+  rect, circle, ellipse, image, svg (Jeremias Ortega).
+
+- #721 - Catch circular references when rendering patterns.
+
+- The C API documentation now uses gi-docgen instead of gtk-doc.
+  Rsvg-convert's man page is now converted to reStructuredText instead
+  of troff.
+
+- The "Recommendations for applications" chapter in the documentation
+  is much improved!
+
+Version 2.53.2
+==============
+
+- #851 - Output filled text as text for PDF; fixes regression due to
+  outputting all text as paths.
+
+- Fix taller-than-wide proportional scaling and size limiting in
+  rsvg-convert.
+
+- #772, #773, #774, #775, #776 - Implement SVG2 geometry properties
+  for these elements: rect, circle, ellipse, image, svg (Jeremias
+  Ortega).
+
+- #450 - Fix potential unaligned accesses in surface iterators
+  (Michael Howell).
+
+- Actually use GDK_PIXBUF_MODULEDIR when calling
+  gdk-pixbuf-query-loaders (Fabrice Fontaine).
+
+- Windows build fixes (Chun-wei Fan).
+
+- Add links to functions and types throughout the C API documentation.
+
+Version 2.53.1
+==============
+
+While it is not a user-visible change, Jordan Petridis has ported
+librsvg's Continuous Integration (CI) infrastructure to use
+Freedesktop CI Templates.  This lets us test librsvg easily on
+different environments.  If you want your environment tested, now is
+the time to add it!
+
+- #599 - Fix incorrect text rendering when text has different scales
+  in the X/Y axes.  This regressed after librsvg 2.52.5, when Pango
+  had to revert its fix for the same bug.  Now librsvg renders all
+  text as paths, and does the scaling itself.  Please file a bug if
+  you have evidence that this presents a performance problem for you.
+
+- Update to the latest gtk-rs release (Bilal Elmoussaoui).
+
+- Port to Freedesktop CI Templates (Jordan Petridis).
+
+- Visual Studio builds can work from a git checkout now (Chun-wei Fan)
+
+- Windows build fixes (Martin Hertz, Chun-wei Fan)
+
+Version 2.53.0
+==============
+
+This is the first release in the new development series.  There are no
+new features, just changes to how the documentation is built.
+
+The man page for rsvg-convert is now generated from a reStructuredText
+document, and the C API reference is generated using gi-docgen.
+
+Please make sure you install python3-docutils (for rst2man) and
+gi-docgen before compiling librsvg from a tarball.
+
+- #755 - rsvg-convert's man page is now generated from reStructuredText.
+
+- #827 - Move C API reference to gi-docgen.
+
+- Test suite updates (Michael Howell).
+
+- Link against bcrypt for Visual Studio builds (Martin Hertz).
+
+Version 2.52.5
+==============
+
+Just bugfixes this time:
+
+- #812 - Fix mangled output in rsvg-convert when redirecting output to
+  a pipe on Windows (Michael Howell).
+
+- #766 - When outputting to SVG, rsvg-convert now uses the
+  width/height units specified in the command line; it always used
+  pixels before (Daniel Petri Rocha).
+
+- #814 - Fix incorrect top/left margins for SVG/PS/EPS/PDF output
+  (Daniel Petri Rocha).
+
+- #599 - Fix incorrect placement of glyphs when text has non-uniform
+  scaling in the X/Y axes.  This is not a librsvg bug, but is fixed by
+  Pango 1.49.3 and later.  Hopefully Pango 1.48.11 will be released
+  soon with this fix as well.  Note that this release of librsvg
+  cannot increase the minimum Pango version to 1.48.11 because it is
+  not released yet.
+
+Miscellaneous:
+
+- Updated crate dependencies: assert_cmd, cast, clap cssparser,
+  float-cmp, itertools, nalgebra, png, proptest, rctree, selectors,
+  system-deps.
+
+Version 2.52.4
+==============
+
+New features:
+
+- #816 - Support the isolation property from the Compositing and
+  Blending Level 1 specification.
+
+- Support Visual Studio 2022 (Chun-wei Fan).
+
+Fixes:
+
+- #818 - The opacity and mix-blend-mode properties were not being
+  applied when an element has a mask.
+
+- Fix panic when an empty group has a pattern fill and filters.
+
+- Fix the tests on Windows; the still only work when Fontconfig is
+  present (Chun-wei Fan).
+
+- Work around a bug in the cairo-rs bindings in the test suite, that
+  only manifests itself in s/390x due to its calling convention.  See
+  https://github.com/gtk-rs/gtk-rs-core/issues/335
+
+Version 2.52.3
+==============
+
+Bugfixes, mostly for text layout.  Also, text links in PDF!
+
+- #17 - Support text-decoration=overline.
+
+- #249 - Basic support for the unicode-bidi property.  Librsvg still
+  considers each tspan independently of others, which is incorrect, but
+  at least bidi-override works now for a single embedding level.
+
+- #804 - Fix placement of tspan that changes the text direction.
+
+- #805 - :lang() selector should now match lang attribute from an
+  element's parent. (Michael Howell)
+
+- #806 - Fix the text-anchor property for right-to-left text.
+
+- #807 - PDF now includes links inside text elements. (Michael Howell)
+
+Version 2.52.2
+==============
+
+Bugfixes and new features!
+
+## New features
+
+Thanks to Michael Howell, rsvg-convert now supports generating
+multi-page PDFs in a sensible way.
+
+With one SVG document per page, each page with the
+SVG's natural size:
+
+  rsvg-convert --format=pdf -o out.pdf a.svg b.svg c.svg
+
+With all pages sized as portrait US Letter, and each SVG scaled to fit
+so that there is a 1in margin around each page:
+
+  rsvg-convert --format=pdf -o out.pdf \
+    --page-width=8.5in --page-height=11in \
+    --width=6.5in --height=8.5in --keep-aspect-ratio \
+    --top=1in --left=1in \
+    a.svg b.svg c.svg
+
+Please see the man page for details.
+
+- #738 - Support <a> elements inside <text>.  Also, support the CSS :link
+  pseudo-class for matching against links. (Michael Howell)
+
+- #649 - Support the CSS :lang() pseudo-class for matching against an
+  element's xml:lang attribute. (Michael Howell)
+
+- #790 - Support the mask-type property from SVG2.
+
+## Fixes
+
+- #800 - Don't panic when a shorthand property is set to
+  inherit. (Michael Howell)
+
+- #788 - Fix regression with the viewport size of interior <svg>
+  elements. (Michael Howell)
+
+- #731 - Allow length units to be case-insensitive, per SVG2. (Kolja Lampe)
+
+## Documentation
+
+- There is now a FEATURES.md in the repository, where you can see all
+  the elements, attributes, and properties that librsvg supports.  We
+  will be adding detail to this gradually.
+
+- For developers, there is now devel-docs/adding-a-property.md with a
+  tutorial on how to add support for new CSS properties.
+
+Version 2.52.1
+==============
+
+This is a bugfix release; there are no new features this time.
+
+## Changes:
+
+- #791 - Fix ordering of tspan inside text elements for right-to-left
+  languages.
+
+- #789 - Fix text-anchor positioning for right-to-left languages.
+
+- #797 - Fix regression in computing sizes when an SVG has only one of
+  width/height and a viewBox.  Thanks to Joshua Fogg for compiling a
+  list of test cases for this.
+
+- #565 - Spec compliance - the writing-mode property applies only to
+  text elements, no to individual tspan elements.
+
+- #794 - Fix build on big-endian platforms.
+
+- Clarify documentation for the rsvg_handle_write() /
+  rsvg_handle_close() deprecated APIs.
+
+Version 2.52.0
+==============
+
+This is a big release!  What follows is a summary from the 2.51.x
+release notes; you can also read them for more detail.
+
+The biggest user-visible change is that rsvg-convert has been ported
+to Rust (Sven Neumann, Paolo Borelli), and it has new features!
+
+## New features in rsvg-convert
+
+### Support for physical units
+
+rsvg-convert is now aware of physical units, and
+fixes a bug where PDFs were created at the wrong size.  Do you need to
+render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
+position of a landscape A4 page?
+
+  rsvg-convert --format=pdf \
+    --page-width=297mm --page-height=210mm \
+    --width=10cm --height=10cm --keep-aspect-ratio \
+    --top=5cm --left=8cm \
+    foo.svg > foo.pdf
+
+Please see the rsvg-convert(1) man page for more details and plenty of
+examples.
+
+### Support for Accept-Language
+
+Previously, librsvg picked up the user's language preferences through
+environment variables like LANG and LC_MESSAGES.  This is inconvenient
+for applications that call rsvg-convert but don't want to synthesize a
+LANG variable.
+
+There is a new option in rsvg-convert so you can pass
+--accept-language=<languages> formatted as an HTTP Accept-Language
+header.  This is used to specify which languages will be chosen from
+elements with the "systemLanguage" attribute:
+
+    rsvg-convert --accept-language=es-MX,en foo.svg
+
+That command will select Mexican Spanish and English from suitable SVG
+elements.  Please see the man page for details.
+
+### Miscellaneous
+
+rsvg-convert's default DPI is now 96, to better match W3C
+standards.  It was 90 before for historical reasons.  We can change
+this back to 90 if it breaks too many scripts.  You can use the
+options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
+
+rsvg-convert no longer supports the "xml" or "recording" output
+formats.  These are useful only for debugging Cairo, not for general
+usage.
+
+## SVG2/CSS3 features
+
+The following features are supported now.  Madds H, John Ledbetter,
+worked on these features.
+
+- transform property from SVG2; previously librsvg only supported the
+  transform attribute from SVG1.1, which has different syntax.
+
+- context-fill and context-stroke for <marker> and <use> elements.
+
+- markers now support orient="auto-start-reverse".
+
+- paint-order for text elements.
+
+- "auto" values for the width and height attributes of the <image>,
+  <rect>, and <svg> elements.
+
+- All the <filter-function> types from the Filter Effects Module Level
+  1 specification: blur(), brightness(), contrast(), drop-shadow(),
+  grayscale(), hue-rotate(), invert(), opacity(), sepia(), saturate().
+
+- The filter property now supports chains of uri() filters or
+  <filter-function> shortcuts.
+
+- Support CSS selectors for attribute matching, like rect[attr^="prefix"]
+
+## New APIs
+
+See the HTML documentation for details:
+
+- rsvg_handle_get_intrinsic_size_in_pixels()
+
+- rsvg_major_version / rsvg_minor_version / rsvg_micro_version
+  variables - used to obtain the librsvg version from languages other
+  than C, since they do not have access to the C macros like
+  LIBRSVG_MAJOR_VERSION.
+
+## Deprecations
+
+The following APIs are deprecated but still available:
+
+- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
+
+- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
+  rsvg_handle_render_element() depending on what you want to do.
+
+Please see the "Migrating from old APIs" chapter in the HTML
+documentation for details.
+
+## News for developers
+
+If you want to run the librsvg test suite easily, there are now Docker
+scripts to do so.  Please see the tools/docker/README.md file for
+details. (Madds H)
+
+There is no leftover C code in the library; all of the implementation
+and the publically-visible symbols are defined in the Rust code.  The
+remaining .h files are all public and do not reflect any .c
+code. (Sven Neumann)
+
+The test suite is now ported to Rust.  The only remaining tests in C
+are for the C API itself (tests/api.c).  With the test suite in
+Rust, the tests are automatically run in parallel across CPU cores,
+making test runs much faster.  (Sven Neumann, Dunja Lalic)
+
+"cargo build", "cargo test" now work without running autotools first,
+so you can in general develop librsvg as a normal Rust project.
+
+The HTML documentation has new chapters; you may find interesting
+things there!
+
+## News for distributors
+
+There is a new list of librsvg releases with security fixes in
+SECURITY.md.  That file also contains security-related information
+on librsvg's dependencies.
+
+The Minimum Supported Rust Version (MSRV) is now Rust 1.52.
+
+## Special thanks
+
+Paolo Borelli and Sven Neumann did a lot of painstaking work to finish
+porting the library and rsvg-convert to Rust.
+
+Sven Neumann and Dunja Lalic ported the test suite to Rust, making it
+much faster.
+
+Dunja Lalic rewrote the Continuous Integration infrastructure, making
+it MUCH faster.
+
+Madds H did their Outreachy internship for librsvg and implemented a
+bunch of useful SVG2/CSS3 features.
+
+John Ledbetter methodically went through all the <filter-function>
+shortcuts and implemented them for SVG2.
+
+Ismael Luceno has been cleaning up our autotools scripts.
+
+Andre Klapper has been wrangling numerous bug reports from Wikimedia
+as usual.
+
+Chun-wei Fan, Abraham Toriz, Christian Hergert, Ignacio Casal Quinteiro
+have been keeping the Windows and MacOS builds working.
+
+
+Version 2.51.4
+==============
+
+- #618 - SVG2: Implement context-fill and context-stroke for markers
+  (Madds H).
+
+- #727 - SVG2: Implement paint-order for text elements (Madds H).
+
+- #747 - SVG2: Support width="auto" and height="auto" for the image element.
+
+- Fix the Windows build (Chun-wei Fan).
+
+- The tools/docker directory now has scripts that developers can use
+  to test librsvg on containers for various Linux distributions.
+
+- Gtk-rs dependency is updated to 0.14.0 (Bilal Elmoussaoui, Chun-wei Fan).
+
+- #758 - Panic when rendering with masks or opacity to a non-image surface.
+
+- #757 - Fix 32-bit builds.
+
+
+Version 2.51.3
+==============
+
+The big news is that rsvg-convert is now aware of physical units, and
+fixes a bug where PDFs were created at the wrong size.  Do you need to
+render an SVG in a PDF file, scaled to 10x10 cm, placed at a certain
+position of a landscape A4 page?
+
+  rsvg-convert --format=pdf \
+    --page-width=297mm --page-height=210mm \
+    --width=10cm --height=10cm --keep-aspect-ratio \
+    --top=5cm --left=8cm \
+    foo.svg > foo.pdf
+
+Please see the rsvg-convert(1) man page for more details and plenty of
+examples.
+
+SVG2 features:
+
+Markers now implement orient="auto-start-reverse".  The work on
+markers is by Madds H., who is doing their Outreachy internship for
+librsvg.
+
+All the <filter-function> types in SVG2 are now supported, thanks to
+John Ledbetter.
+
+- The Minimum Supported Rust Version (MSRV) is now Rust 1.52.  This
+  takes care of CVE-2021-28878 in the Rust standard library.
+
+- #514 - rsvg-convert is now aware of physical units.
+
+- #484 - Markers can now have orient="auto-start-reverse" per SVG2
+  (Madds H - Outreachy internship).
+
+- #711 - Implement the drop-shadow() filter function (John Ledbetter).
+
+- #713 - Implement the hue-rotate() filter function (John Ledbetter).
+
+- #677 - rsvg-convert, do not clip the rightmost/bottomost pixels of
+  an image with partial pixel coverage.
+
+- Partial fix for #668 - Render small caps for fonts that support the
+  "smcp" OpenType feature.  Librsvg and Pango are not yet able to
+  synthesize small caps for fonts that do not support them, but for
+  those that do, they should work fine now.
+
+- #566 - Restrict which elements can appear inside a clipPath, to be
+  spec compliant.
+
+- #746 - Possible cairo_save() without cairo_restore() in render_layer().
+
+- Various updates to the developer's documentation.
+
+
+Version 2.51.2
+==============
+
+This release fixes an important bug about text spacing.  The bug fix
+requires an update to at least Pango 1.44.  Sorry for the increased
+requirements!
+
+Librsvg now supports most of the filter function shortcuts in SVG2;
+see below.
+
+Previously, librsvg picked up the user's language preferences through
+environment variables like LANG and LC_MESSAGES.  This is inconvenient
+for applications that call rsvg-convert but don't want to synthesize a
+LANG variable.
+
+There is a new option in rsvg-convert so you can pass
+--accept-language=<languages> formatted as an HTTP Accept-Language
+header.  This is used to specify which languages will be chosen from
+elements with the "systemLanguage" attribute:
+
+    rsvg-convert --accept-language=es-MX,en foo.svg
+
+That command will select Mexican Spanish and English from suitable SVG
+elements.  Please see the man page for details.
+
+- The Minimum Supported Rust Version (MSRV) is now Rust 1.51.
+
+- Librsvg now requires at least Pango 1.44.
+
+- #730 - Incorrect text spacing when the transform is not 1:1.  You
+  can see this when a small font-size is scaled up due to a
+  transform.  It is less visible for a large font-size scaled down.
+
+- #709 #710 #712 714 #715 #716 #717 - The "filter" attribute now
+  accepts lists of "<filter-function>" per SVG2.  There is support for
+  blur(), contrast(), grayscale(), invert(), opacity(), saturate(),
+  sepia() (John Ledbetter).
+
+- #356 - Add --accept-language option to rsvg-convert.
+
+- #704 - Fix circle/ellipse in paths when they are made out of a
+  single Arc command.
+
+- #691 - Don't allow number lists with unbounded lengths in
+  tableValues attributes, for feComponentTransfer and
+  feConvolveMatrix (Madds H).
+
+- #718 - Negative rx/ry in rect element should be ignored.
+
+- #687 - Reduce memory pressure when rendering text.
+
+- Fix build on 32-bit ARM (Lovell Fuller).
+
+- Update the Rust crate dependencies (Bastien Orivel).
+
+- Refactoring parsers (Paolo Borelli).
+
+- There is a new list of librsvg releases with security fixes in
+  SECURITY.md.  That file also contains security-related information
+  on librsvg's dependencies.
+
+Special thanks to John Ledbetter for carefully implementing each of
+the new shortcuts for filter functions in SVG2.
+
+
+Version 2.51.1
+==============
+
+- The Minimum Supported Rust Version is now 1.48.
+
+- rsvg-convert should fully work on Windows again (Abraham Toriz).
+
+- rsvg-convert's SVG output format uses pixel units instead of points again.
+
+- #699 - Images embedded as data: URLs didn't render if they had a
+  MIME type with a charset parameter.
+
+- #698 - Add limit for too-large radiuses on the feMorphology filter (Madds H).
+
+- #686 - Reduced stack usage (Sebastian Dröge).
+
+- #261 - Parse the enable-background property.
+
+- #703 - Properly ignore elements in an error state inside the "switch" element.
+
+- #695 - Fix cascading mode for the "feImage" element.
+
+- Fix cascading for the "filter" element and filter primitives in general.
+
+- Remove constraints on the types of units used within the "filter"
+  element and filter primitives.
+
+- Reduced memory consumption in general by about 300 bytes per SVG element.
+
+- Update vulnerable crates:
+    smallvec to 1.6.1 (RUSTSEC-2021-0003)
+    generic-array to 0.13.3 (RUSTSEC-2020-0146)
+
+- Lots of cleanups to the build (Sven Neumann).
+
+- Update to gtk-rs 0.9 (Bilal Elmoussaoui).
+
+- Updated ARCHITECTURE.md and documentation in general.
+
+Special thanks to Dunja Lalic for adding the start of code coverage
+analysis to the build.
+
+
+Version 2.51.0
+==============
+
+There are many changes in this development release!  This experimental
+release is meant for early testing, with the understanding that some
+things may be broken, especially since we have large changes to the
+way librsvg's artifacts are built.
+
+The biggest user-visible change is that rsvg-convert has been ported
+to Rust (Sven Neumann, Paolo Borelli).
+
+Please file bugs at https://gitlab.gnome.org/GNOME/librsvg/-/issues/new
+if these changes break your scripts; they are experimental for the
+2.51.x development series:
+
+- #646 - rsvg-convert's default DPI is now 96, to better match W3C
+  standards.  It was 90 before for historical reasons.  We can change
+  this back to 90 if it breaks too many scripts.  You can use the
+  options "--dpi-x=90 --dpi-y=90" to restore the old behavior.
+
+- rsvg-convert's --export-id (-i) option should now have more useful
+  behavior.  This extracts a particular element from the SVG document
+  and renders it scaled to the size specified by the --width/--height
+  arguments, or to the pixel size of the element as if it had no
+  transformations applied.
+
+- rsvg-convert no longer supports the "xml" or "recording" output
+  formats.  These are useful only for debugging Cairo, not for general
+  usage.
+
+Known missing features, which should be restored for the stable release:
+
+- rsvg-convert does not allow stdin/stdout streams on Windows; this is
+  being tracked in issue #676.
+
+The following are changes related to porting to Rust; they are not
+necessarily user-visible, but important for developers of the library:
+
+- There is no leftover C code in the library; all of the
+  implementation and the publically-visible symbols are defined in the
+  Rust code.  The remaining .h files are all public and do not reflect
+  any .c code.  (Sven Neumann)
+
+- The test suite is now ported to Rust.  The only remaining tests in C
+  are for the C API itself (tests/api.c).  With the test suite in
+  Rust, the tests are automatically run in parallel across CPU cores,
+  making test runs much faster.  (Sven Neumann, Dunja Lalic)
+
+- "cargo build", "cargo test" should now work without running
+  autotools first.
+
+- The C API is now implemented on top of the public Rust API, without
+  special hooks into the library's internals.
+
+The following APIs are deprecated but still available:
+
+- rsvg_handle_render_cairo() - use rsvg_handle_render_document() instead.
+
+- rsvg_handle_render_cairo_sub() - use rsvg_handle_render_layer() or
+  rsvg_handle_render_element() depending on what you want to do.
+
+- These deprecations are because the new APIs conform with the web
+  world's view of how SVGs should be positioned and scaled in
+  surrounding content.  Whereas the old APIs were about rendering SVGs
+  to whatever current transformation matrix a Cairo context may
+  contain, the new APIs take a rectangular viewport and librsvg
+  automatically scales the SVG document to fit in it.  The "natural
+  sizing" that was implicit in the deprecated APIs is now explicitly
+  documented, and available through the new API
+  rsvg_handle_get_intrinsic_size_in_pixels().
+
+New APIs:
+
+- rsvg_handle_get_intrinsic_size_in_pixels() converts an SVG
+  document's intrinsic dimensions to pixels, i.e. transforms the SVG
+  document's "width" and "height" attributes to CSS pixels.
+
+New features and bug fixes:
+
+- #615: SVG2: Support a chain of uri() filters in the "filter" property
+  (John Ledbetter, Sven Neumann).
+
+- #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"]
+
+- #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport.
+
+- Fixed CSS "import" so it allows only files from the same base directory
+  (Lars Schmertmann).
+
+- #642 - Fix dx/dy offsets in nested <tspan> elements.
+
+- #601 - Compute correct bounds for objects with stroke-width=0.
+
+- Slight speed improvements in the RGBA premultiplication code (Sven Neumann).
+
+- #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and
+  'css_supported' variables anymore.  These variables were hardcoded
+  to 'true' and unchanged since 2011.
+
+- #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
+
+- Fix the MacOS build (Christian Hergert, Ignacio Casal Quinteiro).
+
+- Deal with missing pkg-config (Ismael Luceno).
+
+- For cross-compilation, check for target-specific prefixed tools like
+  rustc/cargo (Heiko Becker).
+
+Changes in the Rust API:
+
+- #597 - The LoadingError and RenderingError enums have changed, and
+  are now marked #[non_exhaustive].  They will probably change again
+  to hide details of error variants before we make librsvg available
+  as a crate on crates.io.
+
+Special thanks for this release:
+
+- Dunja Lalic for revamping the CI infrastructure and making our CI
+  runs much, much faster - !398.
+
+- Sven Neumann, Dunja Lalic for porting the test suite to Rust.
+
+- Sven Neumann, Paolo Borelli for porting rsvg-convert to Rust and
+  unraveling all the little historical details that were embedded in
+  it.
+
+- Paolo Borelli for constant refactoring.
+
+
+Version 2.50.7
+==============
+
+Two cairo-related bug fixes:
+
+- #745 - Fix mismatched cairo_save/restore when running in inside the Cairo test suite.
+- #746 - Possible cairo_save() without cairo_restore() in render_layer().
+
+
+Version 2.50.6
+==============
+
+This release fixes an important bug about text spacing.  The bug fix
+requires an update to at least Pango 1.44.  Sorry for the increased
+requirements!
+
+- Librsvg now requires at least Pango 1.44.
+
+- #730 - Incorrect text spacing when the transform is not 1:1.  You
+  can see this when a small font-size is scaled up due to a
+  transform.  It is less visible for a large font-size scaled down.
+
+- #704 - Fix circle/ellipse in paths when they are made out of a
+  single Arc command.
+
+
+Version 2.50.5
+==============
+
+- #699 - Images embedded as data: URLs didn't render if they had a
+  MIME type with a charset parameter.
+
+- #691 - Don't allow number lists with unbounded lengths in
+  tableValues attributes, for feComponentTransfer and
+  feConvolveMatrix (Madds H).
+
+- #718 - Negative rx/ry in rect element should be ignored.
+
+
+Version 2.50.4
+==============
+
+Update dependent crates that had security vulnerabilities:
+
+  generic-array to 0.13.3 - RUSTSEC-2020-0146
+
+- #686 - Reduced stack usage (Sebastian Dröge).
+
+- #698 - Add limit for too-large radiuses on the feMorphology filter (Madds H).
+
+- #703 - Properly ignore elements in an error state inside the "switch" element.
+
+
+
+Version 2.50.3
+==============
+
+- #601 - Compute correct bounds for objects with stroke-width=0.
+
+- #545 - Fix MacOS build (Ignacio Casal Quinteiro, Christian Hergert).
+
+- Fix test suite on Rust 1.49 (Sven Neumann).
+
+Version 2.50.2
+==============
+
+- #642 - Fix dx/dy offsets in nested <tspan> elements.
+
+Version 2.50.1
+==============
+
+- #615: SVG2: Support a chain of uri() filters in the "filter" property
+  (John Ledbetter, Sven Neumann).
+
+- #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"]
+
+- #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport.
+
+- Fixed CSS "import" so it allows only files from the same base directory
+  (Lars Schmertmann).
+
+- #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and
+  'css_supported' variables anymore.  These variables were hardcoded
+  to 'true' and unchanged since 2011.
+
+- #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
+
+Version 2.50.0
+==============
+
+- The following is a summary of changes between 2.48.x and 2.50.0.  For
+  full details, please see the 2.49.x release notes below.
+
+- This release requires at least Rust 1.40.
+
+- Windows builds now support ARM64, thanks to Chun-wei Fan.
+
+- Librsvg now consumes much less memory for large SVG files.  The limit for
+  the maximum number of elements in an SVG is bigger now at 1 million
+  elements (this limit exists to avoid unbounded memory consumption by
+  maliciously large files, and is plenty to render even very detailed
+  maps).  Thanks to Sergey "Shnatsel" Davidoff and Adam Reichold for making
+  this possible.
+
+- #34 - The 'font' shorthand in is now supported in CSS.  Librsvg
+  ignores the 'line-height' sub-property because it cannot be done
+  easily with Pango, but everything else in 'font' should work now.
+
+- Many new features from SVG2:
+
+- #508 - radialGradient now supports the "fr" property from SVG2
+  (Dunja Lalic, Corentin Rossignon).
+
+- #568 - Support href attribute in addition to xlink:href per SVG2.
+
+- #560 - Ignore missing filter references per SVG2.
+
+- #607 - Support the mix-blend-mode property from SVG2 and the
+  Compositing and Blending Level 1 specification, so layers can be
+  composited with operators like multiply/screen/color-burn, etc.
+  https://www.w3.org/TR/compositing-1/ (John Ledbetter).
+
+- #473 - Support the paint-order property from SVG2, so one can pick
+  the order in which a path's fill/stroke/markers are drawn (John Ledbetter).
+
+- Many bug fixes and little optimizations; see the 2.49.x release notes for
+  details.  Thanks to Paolo Borelli, Daniel Kolesa, Ernestas Kulik.
+  Sven Neumann, Bastien Orivel, Jordan Petridis, Emile Snyder.
+
+- Special thanks to Sven Neumann for fixing all the cargo-clippy lints.
+
+
+Version 2.49.5
+==============
+
+- #607 - Support the mix-blend-mode property from SVG2 and the
+  Compositing and Blending Level 1 specification, so layers can be
+  composited with operators like multiply/screen/color-burn, etc.
+  https://www.w3.org/TR/compositing-1/ (John Ledbetter).
+
+- #473 - Support the paint-order property from SVG2, so one can pick
+  the order in which a path's fill/stroke/markers are drawn (John Ledbetter).
+
+- Cleanups of the basic drawing and paint-handling code (Paolo Borelli).
+
+- Many style fixes per cargo-clippy (Sven Neumann).
+
+- Improved documentation on the library's internals.
+
+Version 2.49.4
+==============
+
+- Support ARM64 Windows builds (Chun-wei Fan).
+
+- #165 - Draw zero-length paths with square caps correctly (Bastien Orivel).
+
+- #568 - Support href attribute in addition to xlink:href per SVG2.
+
+- #560 - Ignore missing filter references per SVG2.
+
+- #609 - Support the transform attribute again in clipPath (Sven Neumann).
+
+- Update Criterion benchmarks (Ernestas Kulik).
+
+- Update to newer dependencies (Bastien Orivel).
+
+- Many style fixes per cargo-clippy (Dunja Lalic, Sven Neumann).
+
+Version 2.49.3
+==============
+
+- #34 - The 'font' shorthand in is now supported in CSS.  Librsvg
+  ignores the 'line-height' sub-property because it cannot be done
+  easily with Pango, but everything else in 'font' should work now.
+
+- #605 - Compute 'bolder' and 'lighter' font-weight correctly.
+
+- #219 - Make the path parser have a tokenizer/parser (Emile Snyder).
+
+- Fixes for the CI after the gitlab.gnome.org changes (Jordan Petridis).
+
+- Fixed some typos in the documentation (codespell is awesome!).
+
+Version 2.49.2
+==============
+
+- Fix failing tests.
+
+Version 2.49.1
+==============
+
+- (#604) - Fix build on big-endian machines.  Thanks to Daniel Kolesa
+  for testing this repeatedly.
+
+Version 2.49.0
+==============
+
+- Memory consumption of parsed SVG data is greatly reduced.  Property
+  values, path data, and text nodes now use much less memory than
+  before.  Thanks to Sergey "Shnatsel" Davidoff and Adam Reichold for
+  their contributions.
+
+- With that reduction in memory consumption, librsvg can now load up
+  to 1 million XML elements.  This is a hard limit to avoid malicious
+  files consuming arbitrary amounts of memory.
+
+- #508 - radialGradient now supports the "fr" property from SVG2
+  (Dunja Lalic, Corentin Rossignon).
+
+- Sven Neumann has written a fantastic test suite for rsvg-convert(1).
+  Now we can modify this program with confidence.
+
+- Many, many cleanups (Paolo Borelli).
+
+- #594 - Only compute locale information for elements that need it.
+
+- As usual, thanks to Bastien Orivel for keeping dependent crates updated.
+
+- Fix Windows builds without PangoFT2.
+
+- Benchmarks of internal functions work now.  You can run "cargo bench"
+  in librsvg/ and rsvg_internals/.
+
+Version 2.48.5
+==============
+
+- #577 - Support multiple fonts in the font-family property (Bastien Orivel).
+  Previously in font-family="Foo, Bar, Baz" only Foo would get used.
+
+- #591 - Catch overflow when rendering files with a huge viewBox.
+
+- #593 - Don't panic with an empty objectBoundingBox for a mask.
+
+- #596 - Fix introspection data for rsvg_handle_set_stylesheet (Sutou Kouhei).
+
+- Fixes to the librsvg_crate documentation (Abraham Toriz).
+
+- Loading raster images for inclusion in an SVG and producing
+  GdkPixbufs is now faster.
+
+Version 2.48.4
+==============
+
+- #590 - Fix regression when rendering masks.
+
+- #588 - Fix panic when a big viewBox creates an invalid transform.
+
+- #592 - Fix invalid argument to g_log_structured_array()
+
+Version 2.48.3
+==============
+
+- Librsvg now requires glib 2.50.0 or later.
+
+- rsvg-convert's --background-color option now accepts colors with
+  transparency like #rrggbbaa, rgba(...), hsla(...); the transparency
+  value was ignored before (Hao Guan).
+
+- #584 - Fix arithmetic overflow when rendering to large GdkPixbufs.
+
+- #582 - Make librsvg build with Rust 1.39 again.
+
+- #581 - Don't require upcalls into C code for Debian powerpc.
+
+Version 2.48.2
+==============
+
+- Fix linking of the test suite against Harfbuzz.
+
+Version 2.48.1
+==============
+
+- #129 - Fix baseline-shift for simple subscripts/superscripts and
+  absolute offsets.  This should fix a lot of Wikimedia images with
+  formulas.
+
+- #548 - Support images with data: URLs that don't have a MIME-type.
+  This fixes some Open Clip Art images generated by old versions
+  of Adobe Illustrator.
+
+- Fix build of the test suite on Windows (Chun-wei Fan).
+
+- Support running the rsvg_internals tests on Windows (Chun-wei Fan).
+
+Version 2.48.0
+==============
+
+- The following is a summary of changes between 2.46.x and 2.48.0.
+  For full details, please see the 2.47.x release notes below.
+
+- This release requires at least Rust 1.39.
+
+- #379 - New API, rsvg_handle_set_stylesheet(), to set a CSS
+  stylesheet independent of the SVG document.
+
+- #510 - support opacity in patterns.
+
+- Librsvg's XML parser now supports namespaces (xmlns), and is
+  stricter than before about it.  Files may fail to parse if there are
+  attributes or elements with namespace prefixes (e.g. foo:bar instead
+  of plain bar), but without a corresponding namespace declaration
+  (e.g. xmlns:foo="http://example.com/foo").
+
+  This may happen especially with incorrectly-written SVGs that use
+  xlink:href or xi:include attributes without the corresponding
+  namespace declarations.  If you run into this, just add the
+  following to your toplevel SVG element:
+
+      <svg xmlns="http://www.w3.org/2000/svg"
+           xmlns:xlink="http://www.w3.org/1999/xlink"
+	   xmlns:xi="http://www.w3.org/2001/XInclude">
+           ^^^^^^^^^ these ones
+
+- Librsvg no longer depends on libcroco, and now does all CSS
+  processing using Rust crates from Mozilla Servo.  As a result,
+  librsvg can now handle much more complex CSS selectors than before.
+
+- Link-time optimization (LTO) is disabled by default on release
+  builds, as this increased build time too much.  Downstream
+  distributors may want to turn it back on in the toplevel Cargo.toml.
+
+- #515 (CVE-2019-20446) - Librsvg now has limits on the number of
+  loaded XML elements, and the number of referenced elements within an
+  SVG document.  This is to mitigate malicious SVGs which try to
+  consume all memory, and those which try to consume an exponential
+  amount of CPU time.
+
+- Many bugfixes; please see the 2.47.x release notes below.
+
+Version 2.47.4
+==============
+
+- (#240) - Fix rsvg-convert's multipage PDF output when the zoom
+  option is used (Sven Neumann).
+
+- (#547) - Do not stop rendering if an <image> element references a
+  nonexistent file.  This fixes a number of Open Clipart cases.
+
+- (#558) - Compute the font-size cascade correctly when there are "em"
+   #and "ex" units involved.
+
+- Updated the man page for rsvg-convert (Sven Neumann).
+
+Version 2.47.3
+==============
+
+- #379 - New API, rsvg_handle_set_stylesheet(), to set a CSS
+  stylesheet independent of the SVG document.
+
+- #510 - support opacity in patterns (Sven Neumann).
+
+- Move away from the Cairo transform type to our own (Paolo Borelli).
+
+- Update the gtk-rs version.
+
+Version 2.47.2
+==============
+
+- Handling of the "result", "in", "in2" attributes in filter
+  primitives is slightly stricter now, and spec compliant.  Their
+  arguments must be of type CSS custom-ident, so "default", "inherit",
+  "initial", and "unset" are disallowed.  Most SVGs should still work
+  fine.
+
+- #542 - Fix infinite loop when processing CSS sibling combinators.
+
+- #408 - feImage filters no longer clip their output to integer
+  coordinates.
+
+- #504 - Documentation for the Rust crate (available at
+  https://gnome.pages.gitlab.gnome.org/librsvg/doc/librsvg/) now has
+  API usage examples.
+
+- Debug logs from RSVG_LOG=1 should now be more legible and contain
+  better information on invalid CSS.
+
+- Remove link-time workarounds for Rust pre-1.35 (Kleis Auke Wolthuizen).
+
+- Unify internal error types to share the CSS code with gnome-shell.
+
+- Made handling of XML namespaces more spec-compliant.
+
+- Lots of refactoring to start moving away from Cairo internals
+  (Paolo Borelli).
+
+Version 2.47.1
+==============
+
+- Librsvg no longer depends on libcroco!  It now does all CSS
+  processing using Rust crates from Mozilla Servo; these are also the
+  crates that are in use in recent versions of Firefox.  As a result,
+  librsvg can now handle much more complex CSS selectors than before.
+  Fixes #79, #167, #237, #283, #336, #428, #441, #466, #525, #525
+  (Paolo Borelli, Federico Mena).  Thanks to Evgeniy Reizner
+  for fixing https://github.com/servo/servo/issues/22972, which made
+  it possible to use Servo's selectors crate.
+
+- #524 - Panic when reading an invalid stylesheet URL in an XML
+  processing instruction (Paolo Borelli)
+
+- Lots of little improvements to the documentation.
+
+- Link-time optimization (LTO) is disabled by default on release
+  builds, as this increased build time too much.  Downstream
+  distributors may want to turn it back on in the toplevel Cargo.toml.
+
+- We now have the start of documentation on the library's internals at
+  https://gnome.pages.gitlab.gnome.org/librsvg/doc/rsvg_internals/index.html
+  This should be interest of newcomers to librsvg's source code.
+
+Version 2.47.0
+==============
+
+- Librsvg's XML parser now supports namespaces (xmlns), and is
+  stricter than before about it.  Files may fail to parse if there are
+  attributes or elements with namespace prefixes (e.g. foo:bar instead
+  of plain bar), but without a corresponding namespace declaration
+  (e.g. xmlns:foo="http://example.com/foo").
+
+  This may happen especially with incorrectly-written SVGs that use
+  xlink:href or xi:include attributes without the corresponding
+  namespace declarations.  If you run into this, just add the
+  following to your toplevel SVG element:
+
+      <svg xmlns="http://www.w3.org/2000/svg"
+           xmlns:xlink="http://www.w3.org/1999/xlink"
+	   xmlns:xi="http://www.w3.org/2001/XInclude">
+           ^^^^^^^^^ these ones
+
+- Patterns and gradients reused across more than one element will only
+  get resolved once now; this should make things marginally faster for
+  patterns or gradients with fallbacks.
+
+- #515 - Librsvg now has limits on the number of loaded XML elements,
+  and the number of referenced elements within an SVG document.  This
+  is to mitigate malicious SVGs which try to consume all memory, and
+  those which try to consume an exponential amount of CPU time.
+
+- #521 - Compute geometries correctly if there is a viewBox attribute.
+
+- #308 - Fix stack exhaustion with circular references in <use> elements.
+
+- Consistently use the LGPL 2.1 wherever it is mentioned.
+
+- Patterns and gradients reused across more than one element will only
+  get resolved once now; this should make things marginally faster for
+  patterns or gradients with fallbacks.
+
+- #515 - Librsvg now has limits on the number of loaded XML elements,
+  and the number of referenced elements within an SVG document.  This
+  is to mitigate malicious SVGs which try to consume all memory, and
+  those which try to consume an exponential amount of CPU time.
+
+- #506 - Fix empty patterns which reference a fallback pattern with
+  children.
+
+Version 2.46.0
+==============
+
+- The following are highlights compared to the 2.44.x series.  For
+  full details, please see the release notes for the 2.45.x series.
+
+- All of librsvg.so is now implemented in Rust!  That is, except for a
+  very thin wrapper over the public API functions.  Hopefully we can
+  remove this wrapper when Cargo gets some more features around
+  controlling the linking step.  This release requires at least Rust 1.34.
+
+- Librsvg now comes with a Rust crate that can be used from Rust
+  applications.  See librsvg_crate/examples.  This Rust API is
+  designed to be idiomatic; if you want a Rust binding to the shared
+  library instead, please use the "rsvg-rs" crate from crates.io.
+
+- The following API functions are new in the C library:
+    rsvg_handle_get_intrinsic_dimensions()
+    rsvg_handle_render_document()
+    rsvg_handle_render_layer()
+    rsvg_handle_render_element()
+    rsvg_handle_get_geometry_for_layer()
+    rsvg_handle_get_geometry_for_element()
+
+  Correspondingly, there is a new chapter in the documentation, called
+  "Recommendations for Applications".  These new APIs conform better
+  with the web platform's idea of how SVG sizing/positioning should
+  work.  Applications should now find it easier to scale and render
+  SVGs in a single call, instead of having to obtain image dimensions
+  first.
+
+- A bunch of functions have been deprecated but are still available:
+
+    - rsvg_handle_write()/close() are deprecated in favor of the
+      stream functions.  Unfortunately the write()/close() pair
+      require buffering the entire document, in case it is a .svgz
+      compressed file; the streaming functions do not have this
+      problem.
+
+    - Functions that return RsvgDimensionData and RsvgPositionData are
+      deprecated, since they just use integers instead of floating
+      point numbers.  They are replaced with the _get_geometry_*()
+      functions above.
+
+- The library is a lot more strict now in terms of detecting that the
+  API functions are called in the correct order.  For example, calling
+  rsvg_handle_get_dimensions() before rsvg_handle_close() will now
+  emit a critical warning.
+
+- Librsvg is gradually moving towards using code from Mozilla's Servo.
+  We haven't quite gotten rid of libcroco and libxml2 yet, but this is
+  in progress.
+
+- Many thanks to all the people who participated in the long cycle for
+  2.45.  Having the whole library's functionality in Rust is a big
+  accomplishment!
+
+Version 2.45.92
+===============
+
+- #496 - Ensure all lengths and angles parse as finite numbers
+
+- #497 - Don't panic on paths with all-invalid commands
+
+- #500 - Added additional SVG blend-modes for the feBlend filter primitive (Andargor)
+
+- Some changes in the build structure to allow for faster builds.
+
+Version 2.45.91
+===============
+
+- The documentation has a new chapter, Recommendations for Applications.
+
+- #451 - Make rsvg-convert detect images larger than pixman's limit.
+
+- #410 - Update introspection annotations.
+
+- #449 - librsvg_crate: Make cancellable arguments consistent with gio-rs
+
+- librsvg_crate: Take all gio arguments as IsA<SomeGioType> generics
+
+- Updated Rust crates to avoid duplicates (Bastien Orivel)
+
+Version 2.45.90
+===============
+
+- New API functions:
+    rsvg_handle_render_document()
+    rsvg_handle_render_layer()
+    rsvg_handle_render_element()
+    rsvg_handle_get_geometry_for_layer()
+    rsvg_handle_get_geometry_for_element()
+
+  CairoRenderer in the librsvg_crate has corresponding functions
+  as well.
+
+- Fix builds with gettext ≥ 0.20 (Ting-Wei Lan).
+
+- If the C API is called out of order, downgrade hard panics to
+  g_critical() to cope with incorrect/old applications that called
+  rsvg_handle_get_dimensions() before rsvg_handle_close().
+
+- API reference documentation is much improved.
+
+Version 2.45.8
+==============
+
+- This version requires at least Rust 1.34.
+
+- #485 - Fix build on Rust earlier than 1.36 (Kleis Auke Wolthuizen).
+
+- More polishing of the Windows build (Chun-wei Fan).
+
+- Update gtk-rs and dependent crates (Bastien Orivel)
+
+Version 2.45.7
+==============
+
+- Fix #463 - Don't panic if an SVG has character data outside the
+  first element.
+
+- Fix #467: Don't panic when there's an xi:include fallback with no
+  parent element.  Thanks to Bastien Orivel for running afl-fuzz
+  on librsvg.
+
+- Fix #471: Fix blurry semi-opaque objects when rendering with a
+  scaled transformation.  Thanks to the gnome-games people for
+  isolating a test case and to Evgeniy Reizner for providing a more
+  minimal one.
+
+- Fix #481: Don't ignore the first x/y/dx/dy in text/tspan elements if
+  there is more than one position specified.
+
+- #452 - In librsvg_crate, SvgHandle now has a ::has_element_with_id()
+  method.
+
+- rsvg-convert now catches the case where the SVG has no dimensions.
+
+- Replaced the Visual Studio build infrastructure for NMake
+  (Chun-wei Fan).
+
+- This version no longer contains the rsvg-view program, so librsvg no
+  longer depends on GTK.  Please see
+  https://people.gnome.org/~federico/blog/removing-rsvg-view.html for
+  the rationale behind this change.
+
+- The poly element no longer supports "verts" as an alias for the
+  "points" attribute.  The "verts" name was only used in SVG pre-1.0,
+  and we had been cargo-culting that name ever since.
+
+- We now use more machinery from Mozilla Servo, in this case the
+  markup5ever and rust-selectors crates.  This is in line with
+  gradually replacing libcroco with a Rust-only CSS machinery.
+
+- Lots and lots of refactoring and cleanups:  use the rctree crate
+  instead of our own tree representation; remove interior mutability
+  in element structs; make the gradients and patterns code less
+  repetitive (Paolo Borelli).
+
+- Update some dependencies (Bastien Orivel).
+
+- New section in COMPILING.md about cross-compilation to Windows using
+  mingw (Takuro Ashie)
+
+- Fix static linking and Windows builds (Kleis Auke Wolthuizen).
+
+Version 2.45.6
+==============
+- Librsvg now requires Rust 1.30.0 or later.
+
+- Librsvg now requires Cairo 1.16.0 or later.  Thanks to
+  Julian Sparber for keeping up with cairo-rs API changes.
+
+- This version introduces librsvg_crate, an idiomatic Rust crate for
+  using librsvg from Rust programs directly, without using GObject
+  machinery.  This API is subject to change, but you can start using
+  it now in an experimental fashion.  Thanks to Paolo Borelli and
+  Jordan Petridis for fine-tuning this new API.
+
+- All of the librsvg internals are now in Rust!  The C code is just a
+  thin wrapper over Rust functions.
+
+- The internals library has been converted to Rust 2018 (Jordan Petridis).
+
+- Within librsvg_crate, there is a new infrastructure for doing
+  reftests in Rust, that does not depend on PNG reference files.  See
+  librsvg_crate/tests for details.
+
+- This release introduces the following new APIs:
+  rsvg_handle_get_intrinsic_dimensions(),
+  rsvg_handle_get_geometry_for_element().
+
+- Parsing of the "style" attribute, which has a plain list of CSS
+  property declarations, is now done with rust-cssparser.
+- CSS selector matching should be marginally faster than before.
+
+- Fix Visual Studio builds (Chun-wei Fan).
+
+- Fix #11 - Respect the "direction" property for bidirectional text (Khaled Hosny).
+
+- Fix #295 - Ensure the initial viewport fits into temporary surfaces for compositing
+
+- Fix #425 - Don't fail parsing if the system's locale is broken (Paolo Borelli).
+
+- Fix #438, #443 - Don't create intermediate raster surfaces unless
+  absolutely needed.  This was causing blurred output for SVGs from
+  Inkscape and Illustrator, since they include an "enable-background"
+  property even when there are no filters in use.  Thanks to Julian
+  Sparber, Jordan Petridis, Zeeshan Ali for doing a huge "git bisect"
+  to find the cause of this bug.
+
+- Fix #443 - Fix blurry output when enable-background is used without filters.
+
+- Fix #455 - Fix rounding error on i386 (Olivier Tilloy).
+
+- Check for Cairo errors when constructing paths.
+
+Version 2.45.5
+==============
+
+- At build time, you can now pass $CARGO and $RUSTC environment
+  variables if you need to override the default Rust toolchain.
+  Please see COMPILING.md for details.  (Tobias Kortkamp)
+- Fix #405 - In the gdk-pixbuf loader, don't crash if the write()
+  function doesn't receive a GError.
+- Fix #268 - Remove the comp-op property; it's not in SVG 1.1 nor SVG 2.
+- Fix #415 - register RsvgHandleFlags and the RsvgError enum values in
+  a thread-safe fashion (Sebastian Dröge).
+- All of the library's non-GObject functionality is implemented in
+  Rust now.
+- Update the cairo crate (Kornel Lesiński).
+- Clean up the loading code paths (Paolo Borelli).
+- Updated compilation docs for Debian (Jordan Petridis)
+- Updated parts of the reference documentation.
+
+Version 2.45.4
+==============
+
+- Brown paper bag release, my apologies.
+- Fix #402 - Fix the library's soname.  Thanks to Gabriele Balducci
+  for reporting it, and Kalev Lember for fixing it.
+
+Version 2.45.3
+==============
+
+- Big news!  All the real work in the library is now implemented in
+  Rust.  The public API is implemented in C, but most it calls
+  immediately into the Rust code.  Special thanks to Paolo Borelli and
+  Carlos Martín Nieto for making this possible.
+
+- rsvg_handle_set_base_uri() now really assumes that it is passed a
+  URI.  Previously it would try to differentiate between real URIs,
+  and absolute or relative file paths.  If this breaks your code
+  (i.e. you are passing a filename, not a URI), please tell us so we
+  can restore the old behavior!
+
+- Fix #395 - Don't panic in feMorphology if it ends up with a negative
+  scaling transformation.
+- Fix #398 - Detect circular references in gradients.
+- Match the Firefox/Chrome behavior on gradients and patterns with
+  circular references for fallbacks (Paolo Borelli).
+- Fixes for Rust 1.30 and below (Jordan Petridis).
+- Lots and lots of refactoring (Paolo Borelli, Federico Mena).
+
+Version 2.45.2
+==============
+
+- rsvg_cleanup() is now deprecated.  This was only meant to be called
+  from code to be checked by Valgrind.  Leak checkers may show
+  reachable memory from libxml2; real memory leaks should still be
+  reported, of course.  (Kornel Lesiński).
+
+- As an experimental change, librsvg no longer calls xmlInitParser()
+  from libxml2.  Please tell us if this causes problems for
+  multithreaded programs.
+
+- Added g_warning()s to ensure the API is called in the correct
+  sequence.
+
+- The text handling code has been completely refactored and
+  simplified.  This will allow us to implement the x/y/dx/dy
+  properties for multiple glyphs in the future.  Please report any
+  problems you experience in text rendering.
+
+- Fix #385 - Don't crash if there is no rsvg_handle_write() before
+  rsvg_handle_close().
+- Fix #391 - Avoid undefined behavior when casting opaque pointers
+  (Jordan Petridis).
+- Fix crash when a linear RGB filter is followed by an SRGB filter
+  (Ivan Molodetskikh).
+- Fix #393 - Stack overflow when freeing thousands of sibling elements.
+- Fix positioning of adjacent <tspan> elements.
+- All the toplevel loading and drawing code is implemented in Rust now.
+- Pixbuf conversion code is in Rust now (Paolo Borelli).
+- Cleanups in the code for XML processing, markers, attributes (Paolo
+  Borelli).
+- Many build/link fixes (Jordan Petridis).
+- Cleanups in the code that calls libxml2 (Kornel Lesiński).
+
+Version 2.45.1
+==============
+
+- New public API, rsvg_handle_get_geometry_sub(), to get the exact
+  geometry of an element.  The functions
+  rsvg_handle_get_position_sub() and rsvg_handle_get_dimensions_sub()
+  are deprecated now; these returned incomplete data with integer
+  coordinates (Julian Sparber).
+
+- rsvg_handle_write() and rsvg_handle_close() are now deprecated in
+  favor of the functions which use a GInputStream.  The former need to
+  buffer the entire SVG data first; the latter don't need buffering.
+
+- Librsvg no longer tries to load XML entities which reference
+  external resources, either parameter or general entities, declared
+  in the DTD.  This never worked properly, and it is better to do so
+  via the xi:include mechanism.  Also, unparsed external entities with
+  a notation are not really supported in SVG; it has its own <image>
+  element and similar for that purpose.  Only internal general
+  entities are supported now, for example:
+
+     <!ENTITY foo "<some xml here>">
+     <!ENTITY bar "some text here">
+
+- Started support for localized error messages (Daniel García Moreno).
+
+- Ported to Rust: loading code, XML processing code, data: URL parsing, 
+
+- Many code cleanups and refactorings, courtesy of Paolo Borelli.
+- Fix undefined behavior in casts (Jordan Petridis).
+- Cairo/Rust API updates by Julian Sparber.
+- configure.ac cleanups by Maya Rashish.
+

+- Librsvg now requires Cairo 1.15.12.
+- Fix building when srcdir != builddir (Mathieu Bridon).
+- Fix #339 - Panic in filters with primitiveUnits="objectBoundingBox"
+  on zero-sized elements (Ivan Molodetskikh).
+- Fix #335 - Don't panic if the toplevel node is not <svg>.
+- Fixes from fuzz testing (Ivan Molodetskikh): don't panic when the
+  feConvolveMatrix kernel is not set; fix upper bounds in filter pixel
+  getters.
+- Fix #337 - Don't panic with "em" or "ex" units in the font-size property.
+- Fix #338 - Don't panic when an image element doesn't have
+  width/height attributes.

+  this round.
+- Fix #344 - Don't panic when a viewBox has overflowing numbers.
+- Fix #345 - Fix panics due to bad path parsing and overflows in
+  surface size.
+- Updates to the CI infrastructure and the build documentation (Jordan
+  Petridis).
+- Cleanups and refactoring (Paolo Borelli, Linus Unnebäck, Federico Mena).
+- Fix #343 - Handle child being in error in feComponentTransfer.
+- Fix #346 - Handle filter primitives producing errors.
+- Fix #347 - Regression in computation of text element extents.
+- Fix #348 - Fix incorrect font sizing.
+- Fix #349 - Don't panic when loading an external image that is bigger
+  than Cairo's limits.
+- Fix - rsvg_handle_get_dimensions_sub() no longer panics if passed a
+  nonexistent fragment identifier.
+- Fix 32-bit builds (Jordan Petridis).
+- Fix #256 - Correctly match the systemLanguage attribute with the
+  user's locale.
+- Fix #320 - Parse xml:lang correctly.
+- Fix #334 - Don't modify the caller's cairo_t state during rendering.
+- Fix #349 - Don't panic if we get a "data:" URI with empty data.
+- Fix #352 - Don't panic on getting a very large "order" for
+  feConvolveMatrix (Ivan Molodetskikh).
+- Fix #363 - Don't drop spaces around <tspan> elements.
+- Fix #365 - rsvg-convert now uses pixel units for SVG output, instead
+  of points.  This requires cairo 1.15.12 (Antonio Ospite).
+- Fix #358, #366 - tweaks to have the test suite pass on i386 and
+  non-x86_64 platforms (Simon McVittie, Federico Mena).
+- Fix #368 - With RSVG_LOG=1, librsvg will now report when SVGs have
+  references to nonexistent elements, to aid debugging (for example,
+  in an xlink:href attribute).
+- Fix #371 - rsvg-convert was positioning extracted elements
+  incorrectly when using the -w/-h options together with --export-id.
+- Fix #372 - Mis-rendering in small arc segments.
+- Fix #373 - Rendering of gradients for horizontal/vertical stroked
+  lines with gradientUnits="userSpaceOnUse".
+- Fix a couple of memory leaks in the error paths of the GdkPixbuf
+  loader (Benedikt Heine).
+- Allow reference tests with a small difference to pass without
+  breaking the build (Simon McVittie).
+- CSS processing code is now in Rust, although it still calls libcroco
+  to do the parsing.
+- XML processing code is partially moved to Rust, although it still
+  calls libxml2 for the XML parsing.
+- Special thanks to Alex Crichton for ensuring that MacOS builds work.
+
+Version 2.44.2
+==============
+
+- A *double brown paper bag* release!  Super strong, this one!
+- Fix #325 - Don't leak all the elements at the toplevel.
+- Fix #328 - Make masking work on big-endian.  Thanks to
+  Simon McVittie for quick testing of this on s390x.
+- Fix library ordering so -Wl,--as-needed works (Simon McVittie).
+
+Version 2.44.1
+==============
+
+- This is a brown paper bag release!  Apologies for the bugs:
+- Fix #324 - Don't panic if trying to render a non-empty SVG with no
+  elements (Paolo Borelli).
+- Fix #325 - All the elements were being leaked at the toplevel.
+- Fix #326 - Fix COMPILING.md - librsvg 2.44 does not build on Ubuntu
+  18.04 because it has a rust version that is too old.
+
+Version 2.44.0
+==============
+
+- Librsvg now has minimal logging for debugging by setting the
+  RSVG_LOG environment variable.  See CONTRIBUTING.md for details.

+  addition to lengths (Paolo Borelli).
+- Fix #318 - the font-weight property was being parsed incorrectly.
+- Fix #323 - don't use 100% "forever" with malicious SVGs that cause
+  an exponential number of elements to be instanced through the
+  <use> element.  We limit the number of <use> instances now.
+- Fix #293 - Don't panic when masking an empty group.
+- Fix #319 - Parse single font-family correctly.
+- Cleanups for the internal representation of elliptical arcs in paths
+  (letheed).
+
+Version 2.43.4
+==============
+
+- This is an early release to test the effects of threading in librsvg.
+- The lighting and Gaussian blur filters are now parallelized with
+  Rayon; they will use all available cores (Ivan Molodetskikh).
+
+Version 2.43.3
+==============
+
+- Tentative fix: #309 - Don't panic if rendering to a non-image Cairo surface.
+- Optimizations for Gaussian blur and other filters (Ivan Molodetskikh).
+- Optimizations in SRGB <-> linear RGB conversions (Ivan Molodetskikh).
+- More C to Rust conversion in the loading code (Paolo Borelli).
+
+Version 2.43.2
+==============
+
+- All the filter effects have been ported to Rust as part of Ivan
+  Molodetskikh's Summer of Code project!!!!!
+- We now require Rust 1.26.
+- We now include Rust debug information even in release builds, to make it
+  easier to obtain stack traces.
+- Fix #310 - Respect DPI in the font-size property (Mike Marcacci).
+- Fix: draw the circle/ellipse elements with the same orientation as
+  the SVG 1.1 test suite; this is relevant for stroke-dasharray (Ivan
+  Molodetskikh).
+- Refactoring of the drawing code and font sizes (Paolo Borelli).

+- All the style property parsers have been moved to rust-cssparser.
+
+Version 2.43.0
+==============
+
+- This is the start of the 2.43 development series, and you bet we are
+  doing extensive changes!
+- Many, many thanks to Jordan Petridis for keeping our Continuous
+  Infrastructure updated all the time, and for emergency fixes when
+  they were necessary.
+- As part of the Summer of Code 2018, Ivan Molodetskikh is porting the
+  filter effects to Rust.  These are done so far:  core filters
+  infrastructure, feComposite, feMerge, feOffset.  The only remaining
+  SVG elements done in C pertain to filter effects, and Ivan is taking
+  care of them.
+- The feComposite filter now operates in linear RGB space, for better
+  spec compliance.  We transform back to SRGB for the final results
+  (see issue #275 for pending work on fully supporting this
+  elsewhere).
+- Filters now compute their bounds to floating-point values, instead
+  of clipping them to integers.
+- The text, tspan, tref elements are now in Rust (Paolo Borelli).
+- Text rendering should be better.  We now perform text measurement
+  operations with the actual affine transformation that the text will
+  use in the end.  This should give Pango/Freetype a better chance of
+  doing scale-appropriate hinting.
+- The basic styling infrastructure has moved to Rust (Paolo Borelli,
+  Federico Mena).  We don't use the old and limited cascading code
+  anymore.  We also audited which CSS properties are supposed to
+  inherit automatically or not; this should be working per the SVG
+  spec now.  Special thanks to Paolo for doing the largest part of the
+  work in moving the style data to Rust; this was a painstaking,
+  months-long process of constant refactoring.
+- The internals of the drawing infrastructure and bounding-box
+  computation are now done in Rust (Paolo Borelli).
+- Element creation from the parsing stage is now in Rust (Saurav
+  Sachidanand).
+- Clipping and Masking are now done in Rust (Paolo Borelli).
+- Our tests now include the full Adwaita icon theme, so it doesn't
+  break.
+- Fix: #241 - feDistantLight and feSpotLight now work again.
+- Fix: #282 - feComposite is fixed not to overwrite the source image
+  in some cases; this fixes drop shadows generated from Inkscape (Ivan
+  Molodetskikh).
+- We have the beginnings of Windows CI, courtesy of Guillaume Gomez.
+- Changes from 2.42.4:
+- Fix: elements with systemLanguage attributes without variants now
+  work better (Paolo Borelli).
+- gitlab#227 - Fix: we now catch negative values in stroke-dasharray
+  properties instead of leaving the cairo_t in an error state.
+- gitlab#228 - Fix: empty transform attribute now correctly yields an
+  identity transform (Dmitry Kontsevoy).
+- Fix possible crash on invalid gradient references.
+- Make robust against patterns and gradients with no children.
+- Lots of code cleanups and refactorings (Jordan Petridis, Dmitry
+  Kontsevoy, Ivan Molodetskikh).
+- Code moved to Rust: low-level path and PangoLayout drawing, "switch"
+  element (Paolo Borelli).
+- New Rust dependencies: float_cmp, pangocairo crates.
+- We now require Rust 1.21 or later.
+- Changes from 2.42.5:
+- #276 - rsvg_handle_render_cairo() will now refuse to render if the
+  cairo_t passed to it is in an error state.  Fixes a panic in the
+  cairo-dock program.
+- #206 - The test suite now writes test artifacts to tests/output
+  instead of /tmp (Saurav Sachidanand).
+
+Version 2.42.3
+==============
+
+- gitlab#205 - The configure script now checks for Rust 1.20.0 -
+  previously this minimum requirement was not well-defined.
+- gitlab#204 - New feature: If an SVG has an <a> link element, we now
+  generate the corresponding link when outputting to a Cairo PDF
+  surface.  If you use rsvg-convert(1) with PDF output, <a> links in
+  the SVG will work in the PDF (Dmitry Kontsevoy).
+- gitlab#108 - New feature: support font-size:larger and font-size:smaller
+  relative sizes.
+- New feature: rsvg-convert now supports SOURCE_DATE_EPOCH per
+  https://reproducible-builds.org/specs/source-date-epoch/ to generate
+  reproducible output for PDFs (Chris Lamb).
+- gitlab#197 - New requirement: We now require Freetype2 2.9.0, which
+  fixes font rendering bugs.  The test reference PNGs have been
+  regenerated with this version.  You may see changes in font
+  rendering as a result of this updated requirement.
+- gitlab#91 - Fix rendering of masks and clips when the initial
+  transformation has a translation component (Massimo).
+- gitlab#112 - Fix: apply style attributes for all SVG elements, not just
+  for the toplevel one.
+- gitlab#161 - Fix the marker angle for the last vertex of closed
+  paths (Juraj Fiala).
+- gitlab#198 - Fix: Make rsvg_pixbuf_from_file() and its derived
+  functions work again.  Now we have tests for the whole public API.
+- gitlab#143 - Minor optimizations for Gaussian blurs (Timm Bäder).
+- gitlab#201 - Minor speedups in the code to parse SVG attributes.
+- gitlab#178 - Fix some tests that failed on 32-bit machines.
+- COMPILING.md now lists our build dependencies, and has command lines
+  which you can use on openSUSE/Fedora/Debian/Ubuntu/MacOS to set up a
+  development environment for librsvg (Jordan Petridis, Brion Vibber).
+- gitlab#211 - Running the configure script on MacOS now works and
+  doesn't try to use -Bsymbolic for linking (Brion Vibber).
+- gitlab#In addtion to --enable-debug/--disable-debug to control the Rust
+  compilation, now you can use an environment variable
+  LIBRSVG_DEBUG=yes / LIBRSVG_DEBUG=no if you wish.
+- Code moved to Rust: SVG paint servers (Dmitry Kontsevoy), SVG
+  attribute parsing.
+- We now use a Cargo workspace internally, to move more things to Rust
+  (Jordan Petridis, Chun-wei Fan).
+- Special thanks in this release to Jordan Petridis for MAJOR
+  improvements to our Continuous Integration infrastructure, the
+  repository structure, and updates to the compilation documentation.
+  Also for setting up 32-bit builds for continuous integration.
+
+Version 2.42.2
+==============
+
+- gitlab#193 - Don't crash when feConvolveMatrix doesn't specify
+  orderx/ordery attributes.

+
+Version 2.42.1
+==============
+

+- Fixed bugs from Coverity runs (Philip Withnall).
+- Vastly improved README.md, new COMPILING.md, improved CONTRIBUTING.md.

+- Fixed loading files one byte at a time.
+- Reference documentation is now DocBook 5.1.
+- Reference docs now have an overview of the library.
+- Distribute README.md in the tarball properly.
+- Expanded the test suite.
+- Lots of internal refactoring.
+
+Version 2.41.1
+==============
+
+- The feConvolveMatrix filter primitive wasn't being rendered at all;
+  now it works.
+- Pattern specifications can now have a fallback color, per the spec -
+  https://www.w3.org/TR/SVG/painting.html#SpecifyingPaint
+- Tests now use a very basic form of reproducible font rendering.
+  This means that "make check" should pass even if you have a custom
+  Fontconfig setup.
+- Fixed recursive fallbacks in gradients.
+- Per the spec, we now don't render elements which have invalid
+  attributes.
+- Windows build: support building with Fontconfig; support Visual
+  Studio 2017; generate .pc files upon install (Chun-wei Fan)

+  "type" attribute.
+- Fixed bgo#634514 - Don't render unknown elements and their children.
+- Fix parsing of "azimuth", "elevation", "limitingConeAngle" for
+  filter effects.
+- Fixed bgo#785276 - Don't crash on empty or single-byte files.
+- Made the <switch> element work; SVG feature names were being
+  tested incorrectly.
+- Fixed a few cases of uninitialized struct fields.
+- Code converted to Rust: preserveAspectRatio attribute, viewBox
+  attribute, core Node structure, path/line/rect/circle/ellipse basic
+  shapes, group/defs/switch/svg/use/symbol structural elements, pattern element
+  and pattern fallbacks, marker rendering, various parsers, error
+  propagation from parsers, gradient stops, gradient element, 
+- Added a bunch of new test cases for the new features and the
+  code converted to Rust.
+- We now require cairo-rs 0.2.0
+- We now require lalrpop 0.13.1
+- The librsvg tarball now comes with the Rust dependencies embedded
+  using "cargo vendor".  Linux distros can replace these dependencies
+  with their own versions using the infrastructure described in
+  http://doc.crates.io/source-replacement.html
+
+Version 2.41.0
+==============
+
+- The big news is that parts of librsvg are now implemented in the
+  Rust programming language, instead of C.  The public API remains
+  identical.  Rust should provide us with memory safety and nicer
+  built-in abstractions for the code, as well as an easier way to do
+  unit tests.  Special thanks to all the people who sent tips on Rust
+  idioms, and to Sebastian Dröge and Hubert Figuière for the Automake bits.
+- Added an "--enable-debug" option to configure.ac - this will tell
+  the Rust compiler to generate debugging code, instead of working in
+  release mode.  Note that you must still pass CFLAGS by hand by the
+  regular means for the C code.
+- For Windows builds, only MSVC 2012 and upward are supported now.
+- Chun-wei Fan made it possible to regenerate the MSVC project files
+  when Makefile.am changes.
+- Fixed bgo#763386 - handle curveto segments where three control
+  points are coincident.  Thanks to Massimo for the detailed test cases.
+- Fixed bgo#603550 - Compute the luminance correctly when generating a
+  mask.  Thanks to Mike Lewis for the patch.
+- Fixed bgo#776297 - Only render markers in path, line, polygon,
+  polyline elements.
+- Fixed feImage filters when they reference SVG nodes; they were
+  translated incorrectly.
+- Fixed feComponentTransferFunction when there are duplicated feFuncX
+  elements.
+- Fixed bgo#761871 - handle reflection points for quadratic and cubic
+  curves correctly.
+- Fixed bgo#686953 - support the "marker" shorthand property.
+- Fixed a few minor issues pointed out by Coverity.
+- The path data parser now handles boolean values in Arc elements correctly.
+- Fixed conformance bugs in gradient inheritance.
+- Radial gradients now adjust the focus point correctly to be within
+  the gradient's radius.
+- Stroke width normalization is now conformant to the spec.
+- Viewport-relative length normalization is now conformant to the spec.
+- Added some of the official SVG 1.1 test files to our test suite.  Fixed
+  a little bunch of conformance bugs.
+- As a small optimization, we only push/pop CSS states when rendering
+  will actually happen, instead of for all (potentially invisible) nodes.
+- Code that has been converted to Rust:  marker orientations and
+  rendering, path data parser, path building, length normalization,
+  gradient inheritance, bounding boxes with affine transformations.
+- Lots of refactoring to accomodate the Rust code, and general cleanups as well.
+- Added tests/README.md with instructions on how to run the test suite
+  and update it.
+  rsvg-test can now skip files or directories that start with "ignore".
+- Improved the README.
+
+Version 2.40.16
+===============
+
+- Chun-wei Fan added support for building the introspection files under MSVC.
+- Fixed bgo#760262 - Make the zooming options in rsvg-convert(1) work again
+  for scaling the resulting image.  Fix by Menner <mix@gmx.org>.
+- Fixed bgo#764808 - Wikipedia generates equations as SVGs and renders
+  them, but uses fill="currentColor".  Since we don't let callers
+  specify a starting state for CSS, we need to start with opaque black
+  as the default current color.
+- Added documentation for how to replace the deprecated
+  rsvg_handle_set_size_callback().
+
+Version 2.40.15
+===============
+
+- Apologies for the lack of 2.40.14.  I mistakenly tagged the
+  repository before updating the NEWS file.
+- librsvg now uses the Contributor Covenant Code of Conduct, 
+  version 1.4, to which all contributors and maintainers are expected
+  to abide. Please see the code_of_conduct.md file for details.
+- Chun-wei Fan fixed builds on Visual Studio pre-2012.
+- Fixed bgo#759084 - Don't crash when filters don't actually exist
+  Fix by Benjamin Otte.
+- Javier Jardón updated our autogen.sh to use modern autotools.
+- Fixed bgo#761728 - Memory leak in the PrimitiveComponentTransfer
+  filter.  Fix by Ron Hopper.
+
+Version 2.40.13
+===============
+
+- Chun-wei Fan and Paolo Borelli fixed the Windows build.
+- Menner added basic support for the "baseline-shift" attribute in
+  text objects.  We support "sub", "super", and plain "baseline", so
+  you can at least have subscripts and superscripts for formulas and
+  such.  There is no support for percentages or explicit lengths yet.
+  bgo#340047.
+- Menner fixed some duplicate logic when rendering paths, which would
+  try to decide whether to create intermediate surfaces.  Now we have
+  a single place where this is done.  This fixes inconsistent text
+  spacing in some situations.  bgo#749415.
+- Rewrote the markers engine, for bgo#685906 and bgo#760180 - Our
+  machinery for rendering SVG markers (like arrowheads and such)
+  didn't handle several cases correctly.  Curves with coincident
+  control points produced incorrect orientations for the markers, as
+  did multiple contiguous zero-length segments.  We follow the spec
+  for this now and handle things correctly.  Also, markers didn't
+  render in the correct position if they had the viewBox attribute
+  set.
+
+Version 2.40.12
+===============
+
+- Benjamin Otte did *great* work in refactoring the test harness to
+  use Glib's gtest infrastructure, instead of using home-grown
+  machinery.  Tests can simply be put as SVG files in the tests/
+  subdirectories; it is not necessary to list them explicitly in some
+  text file.  Yay!
+- Gzipped SVGs now work if read from streams.
+- References to objects/filters/URIs/etc. are now handled lazily.
+  Also, there is a general-purpose cycle detector so malformed SVGs
+  don't cause infinite loops.  Work by Benjamin Otte.
+- Removed parsing of Adobe blend modes; they were not implemented, anyway.
+- Fixed bgo#700911 - feComponentTransfer filter functions did not work at all.
+- Fixed bgo#630732 - out-of-bounds read in feComponentTransfer with tableValues.
+- Fixed bgo#677068 - incorrect reflection points in paths.
+
+Version 2.40.11
+===============
+
+- Add project files for building on Visual Studio (bgo#753555).  Work
+  by Chun-wei Fan.
+- Added an "--export-id" option to rsvg-convert(1).  This lets you
+  select a single object to export, for example, to pick out a group
+  from a multi-part drawing.  Note that this is mostly useful for PNG
+  output right now; for SVG output we don't preserve many attributes
+  which could be useful in the extracted version.  Doing this properly
+  requires an internal "output to SVG" backend instead of just telling
+  Cairo to render to SVG.
+
+Version 2.40.10
+===============
+
+- Fixed bgo#748608 - Memory leak when Gaussian-blurring.  Thanks to
+  Carlos Garnacho for fixing my leaky code.
+- Fixed bgo#739329 - font-family attributes with singly-quoted names
+  were not handled correctly, yielding incorrect fonts.  Patch by Menner.
+- Fixed bgo#476507 - Path start/end markers didn't have the correct angle
+  if the path was a curve with coincident control points.  Patch by Menner.
+- Fixed bgo#688689 - Support font-style="normal" within a non-normal
+  styled text block.  Patch by Paolo.
+- Fixed builddir != srcdir.  Patch by Matthias Clasen.
+- Remove a bunch of deprecated GTK+ calls.
+- This version of librsvg requires GTK+ 3.10.0, which is, ahem, only two years old.
+  We previously required a version of GTK+ which is four years old.  Out with
+  the old, in with the old.
+
+Version 2.40.9
+==============
+
+- Fixed bgo#738367 - V/v/H/h commands in path elements were not
+  working.  Patch by Andrea Griffini.
+- Fixed bgo#605875 - Gaussian-blurred objects were sometimes missing.
+  Based on a patch by Eduard Braun.
+- Fixed bgo#710163 - use _wfullpath() on Windows when canonicalizing
+  filenames.  Patch by LRN.
+
+Version 2.40.8
+==============
+
+- Bugs fixed from fuzz testing: #744688 - possible double g_free()
+  when processing stroke-dasharray
+- Optimize rendering of polylines, lines, rectangles, circles, and
+  ellipses.  These should be marginally faster, marginally more
+  precise, and should put less pressure on the memory allocator.
+
+Version 2.40.7
+==============
+
+- Bugs fixed from fuzz testing: #703102, #738050, #738169, #744270, #744299
