Release 2016.10

First, this release reverts a previous change to use a mtime of `1`
back to `0`.  This will affect flatpak and users who have set up
build systems to set that mtime, but it restores compatibility
with systems which were using the previous zero value.  For more information,
see ostreedev#495

Another notable bit is we fixed a race condition in pull when the
upstream ref hadn't changed.

OSTree also learned about split metadata/content fetches and
`mirrorlist` URIs.  Generally, the idea with this is that you set up a
centralized set of metadata servers that are secured via pinned TLS
etc., and content fetches can occur via more local mirrors.

Besides that, there is continued work on initramfs-less systems, and
some fixes for resource use during delta generation.

Colin Walters (8):
      repo: Revert default timestamp from 1 back to 0
      delta: Add missing `goto out` for failure to mmap()
      repo: Only use mmap() for metadata > 16k
      delta: Unreference files we've processed
      fetcher: Fix another finalization deadlock
      sysroot: Avoid double cleanup, and ensure no cleanup if specified
      core: Make OSTREE_TIMESTAMP public API

Release 2016.9

This release is mostly smaller fixes.  A few things to
highlight: I'm looking forward to William Manley's continued
work on better support for systems without an initramfs; in
general I hope to make OSTree even more appealing for the
smaller embedded space.

Another thing I want to note is the fix to `rofiles-fuse` has been
another key enabler for rpm-ostree package layering, and should in
general be more useful for anyone doing build systems using OSTree.

Release 2016.8

First, there's some ongoing work in this release to support
systems without an initramfs, which is common in the classical embedded
space.  Thanks to William Manley and Gatis Paeglis!  I expect in the
future to do more work on improving ostree for the embedded case, such
as making more dependencies optional, and notably supporting libcurl.

In working on OCI/OSTree integration, we realized that some
APIs like checkout and archive import weren't introspectable.  There's
a new checkout API that use booleans rather than bitfields, and the
previous one is deprected.

Thanks to Simon McVittie for improving the test suite, and extending
it to Debian on Travis.

This release is also notable for the completion of the port to "libglnx",
so OSTree no longer depends on libgsystem.

Besides that, this release is mostly bugfixes.

Thanks to all contributors!

Release 2016.7

This release is almost entirely bugfixes.  Most notable is a fix for a
relatively rare race condition in the pull code on cleanup (after
completion), and also a memory leak.

Besides that, there are improvements for the test suite, some more
porting away from libgsystem, a bugfix for static deltas important to
flatpak, build tweaks for older glib, etc.

Thanks to all contributors!

Release 2016.6

There's quite a lot of changes in this release since 2016.5, but one
thing I want to call out explicitly is that we fixed a race condition
in the HTTP pull code that could cause hangs or crashes that mostly
occurred only when doing "large" pulls (thousands of object requests).
If this occurs, client systems can work around it by cancelling and
retrying the pull.

Other high level changes:

Jonathan Lebon:
      ostree-repo-libarchive.c: major refactor

This laid more groundwork for rpm-ostree to import RPM (CPIO) archives
sanely.  If you are integrating with an existing package management
format, this should help a lot.

Mathnerd314 (11):
      repo: use OSTREE_TIMESTAMP (=1) for checked-out files

Is a quite interesting change - we previously used a timestamp of
zero, but Nix has apparently done better with `1` for various reasons.
This is a pretty subtle change, so be on the lookout for regressions.

Thanks to all contributors!

Release 2016.5

This release is the first one where the git repository is now
canonically [on Github](https://github.com/ostreedev/ostree).  The
[CONTRIBUTING.MD](https://github.com/ostreedev/ostree/blob/master/docs/CONTRIBUTING.md)
guide is now updated, but the TL;DR is we still support patches to the
mailing list and Bugzilla as well.

This release has a few highlights.  The first is many updates to the
tests - thanks in particular to Simon McVittie is working on
[Debian packaging](https://anonscm.debian.org/git/collab-maint/ostree.git)
and as part of that made numerous fixes to the tests.  Jonathan Lebon
also helped debug some tricky issues resulting from running the tests in
the Docker container for Project Atomic vs in a pbuilder etc.

Jonathan Lebon also added new APIs for the OSTree SELinux handling in
preparation for rpm-ostree package layering work.

Alexander Larsson contributed several new API and feature additions to
improve support for a model where a privileged system helper process
can pull and verify content that was downloaded by an unprivileged
user - i.e. "Install xdg-app system wide".

Colin Walters updated the documentation, including a new section on
[repository management](https://ostree.readthedocs.org/en/latest/manual/repository-management/).

Gatis Paeglis introduced a
[smaller GRUB2 generator](ostreedev#228)
which should be nice for embedded systems - it allows avoiding having
the full GRUB2 binaries on the target system, which are large due to
internal static linking.

Thanks to all contributors!

Release 2016.4

There's a fair amount of stuff in this release, but the `ostree admin
unlock` command has me the most excited.  It actually starts to take
us all of the way back to one of the original visions of OSTree, which
was to make it easy for people to develop/hack on the OS locally,
making it easy to "roll back" to a known good state.

If you found *developing* using an OSTree managed system painful, I
think `ostree admin unlock` command goes a long way towards fixing
that.  There is more to do here, but give it a try!

Other notable changes:

Alexander Larsson and Giuseppe Scrivano both worked on caching the
`summary` file, to avoid redownloading more data than we need to just
to detect "nothing changed".

Colin Walters committed 'lib: Introduce versioned symbols' which is
important for consumers of the shared library to note.

There are updates to the manual, including a new section on writing
buildsystems designed to use OSTree.  Expect more content like this.

Speaking of the shared library some APIs were added so that projects
like rpm-ostree can more precisely watch the sysroot.

Following is a shortlog with the most significant other commits;
thanks to all contributors!

Release 2016.3

This is a quick followup to the previous release.  The build was broken
with `-Werror=format` on 32 bit - we didn't have any 32 bit CI, a problem
which I'll be remedying in the future.

There was also a regression with static delta offline execution as used
by xdg-app.

Besides that, Alex discovered that our handling of endianness in static
deltas was wrong - we tried to canonicalize everything to big endian,
but the size was missing.

Newly generated deltas will now have an endianness marker which we
will honor.  For older deltas, we'll apply some heuristics which in my
testing work well (basically if the delta sizes are in exabytes,
that's probably byteswapped).

Release 2016.2

First, this release has us start taking documentation more seriously.
The man pages and API doc are unchanged, but the "manual" has moved out
of gtk-doc, been converted to Markdown for use with `mkdocs`.

This is available at: https://ostree.readthedocs.org/en/latest/

The static delta design documents are moved into the manual as well.
Look for more updates here in the future around things like designing
build systems, managing repositories, more implementation details,
etc.

Speaking of static deltas, there is now support in the pull API (and
command line) for showing how much content data would be downloaded
(and used uncompressed).  This is intended for use with OS updater
command lines and GUIs (like Cockpit).

Another notable change is that we've merged in a FUSE utility called
`rofiles-fuse`.  This doesn't itself depend on OSTree, nor does OSTree
depend on it, but they're very useful together.  Specifically, if one
is designing a build system that uses OSTree, or running the
equivalent of RPM `%post` scripts, `rofiles-fuse` can help ensure that
the build process doesn't mutate any of the hardlinks.  Though this
can also be addressed through container runtimes, not all systems are
ready to expose container features to unprivileged users.

There is also some improvements in underlying infrastructure for
supporting import and export of Docker images.  The primary changes
here are better tar support, and OSTree now understands "whiteout"
files, and optionally processes them during checkout.

Besides this, there are various bugfixes, including a notable one to
fix use of client side TLS certificates.

Thanks to all contributors!

Release 2016.1

Notable commits:

* Alexander Larsson contributed changes to better isolate concurrent use of
  OSTree pulls into the same repository:

      repo: Use per-transaction staging dir
      repo: Allocate a tmpdir for each OstreeFetcher to isolate concurrent downloads

* Colin Walters added two new APIs that make it easier to optimize
  committing new trees from previously generated content:

      repo: Expose dfd-relative mtree writes as public API
      repo: Add APIs for devino optimization between checkout -> commit

  and contributed build fixes as well as internal optimizations for deployment writing.

* Giuseppe Scrivano enhanced the prune command:

      prune: add new flag --static-deltas-only

* Jonathan Lebon made `grub2-mkconfig` work reliably when *not* run by OSTree:

      grub2_generate: load sysroot before using it

* Matthew Barnes added a new remote command:

      remote: Add "ostree remote summary" command

  and contributed several other cleanups inside the HTTP fetcher.
