NEWS for Morph
==============
This file contains high-level summaries of user-visible changes in
each Morph release.
Version 14.28, released 2014-07-10
----------------------------------
* Fix failure to update some cached git repos
* Fix and clarify chunk splitting
Version 14.26, released 2014-06-27
----------------------------------
* Smarter git caching behaviour, cached repos will only be updated when
necessary
* Morph deploy now lets the user specify which systems they want to deploy
within a cluster
* Various bug fixes
Version 14.24, released 2014-06-13
----------------------------------
* rawdisk deployments check that they have the btrfs module loaded first
* distbuild should busy-wait less
* fetching of artifacts should be atomic, so a failure to fetch the
metadata of an artifact doesn't confuse the build system when we have
the chunk, but no metadata
* `morph deploy` now defaults to `--no-git-update`
* `morph gc` now cleans up failed deployments, so they aren't left around
if morph terminates uncleanly
* `morph edit` now only takes the name of the chunk, rather than the
name of the system and stratum that chunk is in
Version 14.23, released 2014-06-06
----------------------------------
New feature:
* Initramfs support
There have also been a number of fixes to distbuild, and the
`morph copy-artifacts` command has been replaced by `morph list-artifacts`.
Version 14.22, released 2014-05-29
----------------------------------
New features:
* VirtualBox deployment now supports Vagrant. See:
<http://wiki.baserock.org/guides/vagrant-basebox/>
* Additional checks when deploying upgrades with the 'ssh-rsync' extension.
Additional bug fixes described in the git log.
Version 14.20, released 2014-05-14
----------------------------------
New features include:
* New CPU architecture: armv7lhf (ARM hard float).
* Artifact splitting for chunk and stratum artifacts.
* Components that can be used to set up a distributed build network of Morph
build workers.
* Built-in documentation for some extensions, see `morph help-extensions` and
`morph help <extension>`.
* Nested deployment by `morph deploy`.
* Support for adding binaries to Git repos when used with Trove. See the `morph
add-binary` and `morph push` commands.
Many additional changes are described in the Git log.
Version 13, released 2014-01-10
-------------------------------
New features added:
* New CPU architecture: ppc64 architecture (POWER PC 64-bit). This is
the change specific for Morph. There are changes to the morphologies
(in a different git repository) to actually build such systems.
* `morph build` and `morph deploy` now allow `.morph` suffixes in
command line arguments. The suffixes are stripped internally, so
Morph behaves as if they suffix wasn't there in the first place.
* The `morph build` command is now a new implementation. The old
implementation is still available as `morph old-build`, just in case
the new code is buggy, but will be removed in a future release.
Likewise, `morph deploy` has a new implementation, but no
`old-deploy`. Both new implementations should work exactly as the
old ones, except for bugs.
Bugs fixed:
* When Morph reads git configuration files, it now correctly handles
whitespace at the end of configuration values.
* `morph deploy` no longer creates and pushes a temporary build
branch. Pushing it wasn't useful, merely wasteful.
* `morph deploy` now allows cross-architecture deployments, and
and `morph cross-bootstrap` checks that the system is being built
supports the target architecture.
Other user-visible changes:
* When preparing to build (when construcing the build graph), Morph
now reports the ref (SHA1) it uses for each stratum.
* Systems being built must now have at least one stratum, and the
strata in a system must have at least one chunk that is built using
the normal (staging area) mode, rather than bootstrap mode.
Version 12, released 2013-11-15
-------------------------------
* NEWS file added.
