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!

OSTree
New! See the docs online at Read The Docs (OSTree)
OSTree is a tool that combines a "git-like" model for committing and downloading bootable filesystem trees, along with a layer for deploying them and managing the bootloader configuration.
OSTree is like git in that it checksums individual files and has a content-addressed-object store. It's unlike git in that it "checks out" the files via hardlinks, and they should thus be immutable. Therefore, another way to think of OSTree is that it's just a more polished version of Linux VServer hardlinks.
Features:
- Atomic upgrades and rollback for the system
- Replicating content incrementally over HTTP via GPG signatures and "pinned TLS" support
- Support for parallel installing more than just 2 bootable roots
- Binary history on the server side (and client)
- Introspectable shared library API for build and deployment systems
This last point is important - you should think of the OSTree command line as effectively a "demo" for the shared library. The intent is that package managers, system upgrade tools, container build tools and the like use OSTree as a "deduplicating hardlink store".
Projects using OSTree
rpm-ostree is a tool that uses OSTree as a shared library, and supports committing RPMs into an OSTree repository, and deploying them on the client. This is appropriate for "fixed purpose" systems. There is in progress work for more sophisticated hybrid models, deeply integrating the RPM packaging with OSTree.
Project Atomic uses rpm-ostree to provide a minimal host for Docker formatted Linux containers. Replicating a base immutable OS, then using Docker for applications meshes together two different tools with different tradeoffs.
flatpak uses OSTree for desktop application containers.
GNOME Continuous is a custom build system designed for OSTree, using OpenEmbedded in concert with a custom build system to do continuous delivery from hundreds of git repositories.
Building
Releases are available as GPG signed git tags, and most recent versions support extended validation using git-evtag.
However, in order to build from a git clone, you must update the submodules. If you're packaging OSTree and want a tarball, I recommend using a "recursive git archive" script. There are several available online; this code in OSTree is an example.
Once you have a git clone or recursive archive, building is the same as almost every autotools project:
env NOCONFIGURE=1 ./autogen.sh
./configure --prefix=...
make
make install DESTDIR=/path/to/dest
