2019.6

Nothing major in this release, but we have some
bigger stuff outstanding and ready to merge, so I
want to get this release out so that work will
have time to stabilize.

A few build/CI fixes. A new progress API which
will be used by flatpak (and can be used by others).
Finally, we also avoid reordering kernel arguments.

Thanks to all contributors!

2019.5

Mainly in this release:

• We discovered that CLang has a static analyzer scan-build;
  it found some small memory leaks so far, otherwise mostly
  noise, but we haven't dug through all the errors yet.
• Gained a new zipl (s390x bootloader) backend
• Install the .hmac files needed for FIPS mode in /boot too

This is also the first release where we switched to using
the OpenShift Prow as a merge bot, though a lot more CI work
is pending.

v2019.4

This is mostly a bugfix release. Notably, the 2019.3 release caused some issues
related to the gpg-agent code spewing messages on the terminal. Additionally,
Fedora 31 users have hit upon issues with ostree-finalize-staged.service
running too late to be able to write back its logs to the journal. This then
confused rpm-ostree after reboot, because it looks at the previous boot's
journal for this message.

The biggest feature-ish change is support for a partial commit "reason" so that
after ostree fsck --delete was used, subsequent ostree fsck will continue to
report an error. This should be used by higher level tools that want to do
"fsck and repair". It's likely at some point that "fsck and repair" logic will
move down into the libostree core as well.

There are ongoing efforts to port Fedora CoreOS to s390x: one fix landed here to
add the deployment prefix to BLS entries since it's what the zipl bootloader
expected.

Special thanks to first-time contributors Benjamin Gilbert and Jason Wessel!

2019.3

A lot of changes since the last release. On the feature side,
probably the biggest is we've made public the internal API
for kernel arguments, which rpm-ostree now uses.

Other things include a new --modern switch for init-fs,
better support in pull for downgrade protection, better
use of mmap, support for committing archives (tarballs)
from stdin, etc.

Finally, libostree now supports being built without GPG,
which is an important preparatory piece for introducing
an alternative signature system - look for more work
on that soon.

Thanks to all contributors!

2019.2

It's been some time since the last release, so this is a slightly larger
one! There's lots of new features, and a few bug fixes. Some highlights
below.

New features:

• A new sysroot.bootloader key was added to be more explicit about
  which bootloader OSTree should use. Notably a none value is
  supported, in which OSTree is solely responsible for writing the BLS
  entries. This can then be used by bootloaders like GRUB2, which now
  supports BLS natively. (#1814)
• ostree config now supports the unset command to unset a key from
  the OSTree repo config (#1743)
• ostree remote add now supports the --force flag to replace a
  remote of the same name if it exists (#1166)
• ostree-prepare-root now logs a structured journal message after
  finding the deployment to which to pivot. This can be used by
  higher-level apps like RPM-OSTree to build a history of the
  deployments the machine was booted into. (#1842)
• The staging API now supports a lockfile which prevents finalization at
  shutdown. This is intended to be used in systems like Fedora CoreOS,
  which needs more fine-tuned control between staging a deployment,
  and setting it as the default deployment on reboot. (#1841)
• ostree static-delta show now prints the From and To commits for
  which the delta was generated (#1823)

Bug fixes:

• Make looking up collection-refs similar to how regular refs are looked
  up, i.e. first in the transaction, then in the current repo, and then
  in the parent repo (#1821)
• Don't include the OSTree commit version number twice in the boot menu
  title. This affected at least Fedora-based systems composed with
  RPM-OSTree's mutate-os-release. (#1829)
• Activate ostree-finalize-staged earlier; this should hopefully make
  deployment finalization more reliable by running it later in the
  shutdown sequence, when less services are running (#1840)
• Run grub2-mkconfig on the filesystem tree of the pending deployment,
  rather than the previously deployed tree. This was a corner case where
  the deployment failed if a previous deployment did not exist, on
  systems where grub.cfg is used. (#1831)

As always, thanks to all the contributors!

2019.1

This is the first libostree release of 2019; no big changes, just a collection of smaller
features and bugfixes.

On the features side, a good example is:
lib/repo: Search a list of paths in gpgkeypath for gpg keys
from PR #1773 - this will be useful for Fedora which rotates GPG keys
across releases.

Another feature is grub2: add support for devicetree
from PR: #1790

lib/kargs: allow empty-list arguments i.e. PR #1785 is between a
bugfix and feature - it ensures libostree supports "empty list" kernel
arguments.

There's also some ongoing work to have libostree be a "backend"
for OCI/Docker container storage; checkout: honor opaque checkouts
in PR #1486 is part of that.

pull: If built with --disable-http2, allow enabling via http2=1 from
PR #1798 will allow people to more easily play with HTTP2 if
it's disabled by default.

Thank you to all contributors!

2018.9

https://github.com/ostreedev/ostree/releases/tag/v2018.9

It's been two months since our last release, so this one is slightly
larger than usual (the ~monthly cadence). It's mostly bugfixes
again, although there were some API additions and new
configuration options.

These new features are things like:

• Allow disabling pulling from LAN/USB/Internet (#1758)
• lib/repo: Add an API to get min-free-space-* reserved bytes (#1715)
• OstreeMutableTree: add _remove method (#1724)
• repo: Add a checkout option to not hardlink zero-sized files (#1752)

On the bugfix side, nothing major; we have the usual small memory
leak fixes (yeah, we use GCC autocleanups, but still, this is C).
Beyond that, good examples of bugfixes are:

• finalize-staged: Bump timeout to 5 minutes (#1755)
• deploy: Fix removing /var/.updated with separate /var mount (#1730)
• src/ostree: Don't delete refs having aliases (#1749)

One notable change in this release is the initrd service
ostree-prepare-root.service now runs earlier in the boot process.
This shouldn't actually affect OSes, unless there's extended logic
in the initrd that integrates tightly with OSTree. The use case for this is
better integration with Ignition, which will be used in Fedora CoreOS.
PR: #1759

Another systemd related change is the introduction of a path unit:
ostree-finalize-staged.path. This allows the service of the same name
to be path activated instead of explicitly started at deployment staging time.
This release however does not yet rely on this mechanism to give time for
packagers and integrators to adapt to the new unit (e.g. by enabling it in
the systemd presets). A future release will require this.
Note that deployment staging is still not the default for libostree, although
at least rpm-ostree now unconditionally uses staging, and while it
generally worked well, we hit issues with people using slower hard drives,
hence the increase in timeout in PR #1755 .
PR: #1740

Another change to call out is:
lib/commit: Don't chown objects to repo target owner (#1754)
We previously had incomplete support for a process running as uid 0
writing to a repository owned by a non-zero uid, but it was never finished.
This will likely be revisited at a later time.

We also merged:
lib/grub2: Support Debian-style grub.cfg path (#1714)
from a new contibutor (thanks Felix!). Who incidentally also
posted recently about new Rust bindings:

Thanks a lot to all contributors!

2018.8

This release is pretty much all minor bugfixes: memory leaks,
fixing error messages and docs, handling a race condition
on pull with summary updates. There's one new feature (noted below),
and we also gained a new contributing tutorial:
https://mail.gnome.org/archives/ostree-list/2018-August/msg00005.html
Thanks to Robert Fairley and Cheryl Fong!

The one bugfix I want to call out explicitly is:
ostree-remount.service: RemainAfterExit=yes
PR: #1697
It's surprising it took us so long to find and fix this; I've seen
occasional boot failures that I believe trace down to this problem.
The behavior of systemd units of Type=simple without RemainAfterExit=yes set
is rather nonsensical; I may try to push to have a warning emitted
upstream if such a unit is a dependency of another.

And the one new feature is the auto-update-summary config option
for repositories. For more information, see the docs and
PR: #1681

Thanks to all contributors!

2018.7

I've said this before but the regular variety of contributors to libostree
makes me very happy - part of the reason I like working on Free Software
is collaborating with smart people around the world! Thanks to all of you!

There's no one major feature in this release, but we have a variety
of improvements and bugfixes.

The addition of min-free-space-size in the previous release caused
issues with older libostree/flatpak interacting with it. We now tolerate
both min-free-space-size and min-free-space-percent being set for
compatibility.
PR: #1685

The way libostree writes bootloader spec snippets has changed to
have the version number first, aiding sorting. It turns out some BLS
implementations order via filename. This is preparatory work for more
directly adopting the BLS in Fedora (and I for one will not miss grub2-mkconfig
and particularly os-prober)!

libostree became significantly smarter about handling "recommitting" content,
such as ostree commit --tree=ref=foo -b bar; it's now nearly free, and this
can be extended to very quickly "union" or merge different refs into a unified
whole. See the discussion in:
PR: #1643

There are two fixes for staged deployments (still not the default), but
we're aiming to do that by default in rpm-ostree soon, and that's shaking
out some remaining issues (for example, the API didn't support overriding
kernel arguments correctly).

Another notable bugfix is for separate /var partition, which we regressed
in 2018.6 as part of working on Ignition integration.
PR: #1668

v2018.6

This release includes the final merge of the previously "experimental" API
for peer-to-peer discovery/download. This is currently supported by Flatpak
and the EndlessOS updater. One use case for example that this improves
is the "update via USB stick" case; you'll need to set collection IDs, and
have your update system use the repo finder API. (Today ostree admin upgrade
doesn't). Thanks a lot to Endless for all of their work on this!
PR: #1596

libostree learned how to retry HTTP requests on transient network errors.
By default, requests on such errors are now retried 5 times.
PR: #1594

There is also now a new "min-free-space-size" config option. This is similar
to the "min-free-space-percent" option but instead takes absolute values, such
as "1GB" or "10MB".
PR: #1616

The original systemd design for ConditionNeedsUpdate= didn't quite work
with libostree, but Endless wrote a fix and had been shipping it for a while.
That's now been merged: deploy: Delete .updated file from /etc and /var on new deployments
Part of the reason this came up now is we're planning to change rpm-ostree
to switch to systemd-sysusers: coreos/rpm-ostree#49
And today sysusers uses ConditionNeedsUpdate=. Once we make
the switch in rpm-ostree and test it out I'd recommend other operating
systems follow (and not use nss-altfiles). And if you've already made the switch,
let us know!
PR: #1631

We're working on using https://github.com/coreos/ignition for Fedora CoreOS,
which means integrating it with libostree. As both run in the initramfs,
we added a simple change to ensure /var is mounted. A future enhancement
here will likely involve handling custom /var mounts too.
PR: #1617

There are a variety of other changes, like fsck --all, having u-boot support devicetree,
etc.
