libpng-1.2.41beta19-[previous version]-diff.txt
Changes since the last public release (1.2.40):
version 1.2.41beta01 [September 25, 2009]
Moved redundant IHDR checking into new png_check_IHDR() in png.c
and report all errors found in the IHDR data.
Eliminated useless call to png_check_cHRM() from pngset.c
Expanded TAB characters in pngrtran.c
version 1.2.41beta02 [September 30, 2009]
Revised png_check_IHDR().
version 1.2.41beta03 [October 1, 2009]
Revised png_check_IHDR() again, to check info_ptr members instead of
the contents of the returned parameters.
version 1.2.41beta04 [October 7, 2009]
Added "xcode" project similar one already in libpng-1.4.0beta (Alam Arias).
Ported some cosmetic changes from libpng-1.4.0beta86.
Eliminated a shadowed declaration of "pp" in png_handle_sPLT().
version 1.2.41beta05 [October 17, 2009]
Revised pngconf.h to make it easier to enable iTXt support. From libpng
version 1.2.9 through 1.2.40, defining PNG_iTXt_SUPPORTED did not work
as expected.
Ported some cosmetic changes from libpng-1.4.0beta87, changing
many "#if defined(x)" to "#ifdef x".
version 1.2.41beta06 [October 18, 2009]
Restored PNG_USE_LOCAL_ARRAYS code in pngread.c that was inadvertently
deleted in libpng-1.2.41beta05.
Converted all PNG_NO_* tests to PNG_*_SUPPORTED everywhere except pngconf.h
as in libpng-1.4.0beta78 and later.
version 1.2.41beta07 [October 21, 2009]
Ported some cosmetic changes from libpng-1.4.0rc01, changing
many "#if defined(x)" to "#ifdef x" in png.h and pngconf.h.
version 1.2.41beta08 [October 30, 2009]
Ported from libpng-1.4.0rc01: png_calloc(), png_get_io_chunk_name(),
png_get_io_state(), png_set_user_cache_max(), png_get_user_cache_max(),
png_set_premultiply_alpha, and png_do_read_premultiply_alpha().
Relocated png_do_chop() ahead of building gamma tables in pngrtran.c
This avoids building 16-bit gamma tables unnecessarily.
version 1.2.41beta09 [November 1, 2009]
Removed a harmless extra png_set_invert_alpha() from pngwrite.c
More bugfixes and improvements to CMakeLists.txt (Philip Lowman)
Moved CMakeLists.txt from scripts into the main libpng directory.
Apply png_user_chunk_cache_max within png_decompress_chunk().
Merged libpng-1.2.41.txt with libpng-1.4.0.txt where appropriate.
version 1.2.41beta10 [November 1, 2009]
Enabled iTXt support by default. To ensure binary compatibility with
previous versions, the "lang" and "lang_key" members will be assumed
to be omitted from previous versions unless the current libpng
version was built with PNG_iTXt_SUPPORTED (which is otherwise no
longer necessary to gain iTXt support), as a signal that the user has
been building previous versions with PNG_iTXt_SUPPORTED as well.
version 1.2.41beta11 [November 2, 2009]
Store user's user_png_ver in new png_ptr->user_png_ver element.
Revised iTXt support. To ensure binary compatibility with
previous versions, the "lang" and "lang_key" members will be assumed
to be omitted from versions prior to 1.2.41beta11 whenever there is a
library mismatch.
version 1.2.41beta12 [November 2, 2009]
Free png_ptr->user_png_ver when destroying png_ptr.
version 1.2.41beta13 [November 3, 2009]
Updated scripts/pngw32.def and projects/wince/png32ce.def
Copied projects/wince/png32ce.def to the scripts directory.
Added scripts/makefile.wce
Patched ltmain.sh for wince support.
Added PNG_CONVERT_tIME_SUPPORTED macro.
version 1.2.41beta14 [November 8, 2009]
versions 1.2.41beta05 through 1.2.41beta13 were abandoned.
Make inclusion of time.h in pngconf.h depend on PNG_CONVERT_tIME_SUPPORTED
Make #define PNG_CONVERT_tIME_SUPPORTED depend on PNG_WRITE_tIME_SUPPORTED
Reverted iTXt compatibility stuff from 1.2.41beta05, 1.2.41beta11, and
1.2.41beta12.
Reverted IOSTATE feature, user_cache_max, and premultiply_alpha features
from 1.2.41beta08.
Retained png_calloc() from 1.2.41beta08 but as a non-exported function,
and removed reference to png_calloc from scripts/*.def
version 1.2.41beta15 [November 8, 2009]
Added PNG_DEPSTRUCT, PNG_DEPRECATED, PNG_USE_RESULT, PNG_NORETURN, and
PNG_ALLOCATED macros to detect deprecated direct access to the
png_struct or info_struct members and other deprecated usage in
applications (John Bowler).
Updated scripts/makefile* to add "-DPNG_CONFIGURE_LIBPNG" to CFLAGS,
to prevent warnings about direct access to png structs by libpng
functions while building libpng. They need to be tested, especially
those using compilers other than gcc.
Updated projects/visualc6 and visualc71 with "/d PNG_CONFIGURE_LIBPNG".
version 1.2.41beta16 [November 9, 2009]
Removed three direct references to read_info_ptr members in pngtest.c
that were detected by the new PNG_DEPSTRUCT macro.
Only #define PNG_DEPSTRUCT, etc. in pngconf.h if not already defined.
version 1.2.41beta17 [November 10, 2009]
Updated CMakeLists.txt to add "-DPNG_CONFIGURE_LIBPNG" to the definitions.
Marked deprecated function prototypes with PNG_DEPRECATED.
Marked memory allocation function prototypes with PNG_ALLOCATED.
Changed png_check_sig() to !png_sig_cmp() in contrib programs.
Corrected the png_get_IHDR() call in contrib/gregbook/readpng2.c
Added "-DPNG_CONFIGURE_LIBPNG" to the contrib/pngminum makefiles.
version 1.2.41beta18 [November 11, 2009]
Renamed scripts/makefile.wce to scripts/makefile.cegcc
Marked nonexported functions with PNG_PRIVATE macro.
version 1.2.41beta19 [November 12, 2009]
Revised scripts/*.def to reflect functions actually exported by libpng.
