This is mostly a bugfix release with minor feature enhancements.  The
effort formerly called "rpm-ostree jigdo" is now known as "rojig" due to
confusion with the original jigdo project.  The tracking issue:
https://github.com/projectatomic/rpm-ostree/issues/1081 is now updated,
and this release changes various parts of the UI as well as lots of
internal code to use the new term.
PR: #1279

Automatic updates have received some fixes and small performance
improvements. One notable change is that output from the automatic
trigger service is now emitted by the rpm-ostreed service itself, making
it easier to trace down issues. Some other related regressions have also
been fixed.
PR: #1268 #1278

The libostree project [gained pinning](https://github.com/ostreedev/ostree/pull/1464)
which is a way to explicitly retain deployments.  This rpm-ostree
release learned to display them. A future release will likely teach the
rpm-ostree CLI to set them.
PR: #1292

The `db diff` command has learned to make diffs against the booted
deployment more natural. For example, `db diff` on its own, will now
diff the booted deployment against the pending one. See the man pages
for more information.
PR: #1294

The `db list` command now also knows to look for the new pkglist commit
metadata. This means that it is no longer necessary to download the full
rpmdb of a commit to print the list of RPMs contained.
PR: #1299

There is a new public `Reload` DBus API which may be used by clients to
ensure the daemon is up-to-date.  It is now considered best practice to
invoke this method before each interaction with the daemon.   The
`rpm-ostree` CLI now does this; notably this closes some race conditions
one might see when using `ostree admin` concurrently with `rpm-ostree`.
