~~~~~~~~~~~~~~~~~~~~~~~~~

**Web interface**

- Show last snapshot size distribution, and first backup success date,
in hostconfig edit-view.
- Show real-used-size instead of apparent-used-size in snapshot data
distribution. If you have ZFS compression enabled, you'll see a drop
in the snapshot size summaries (not in the total disk usage).
- Hide last-error message in hostconfig edit-view for hosts that are
disabled.

**Other**

- Single Sign-On (Discourse style) can be enabled (using the optional
kleides-dssoclient dependency). See KLEIDES_DSSO_ENDPOINT option.
- Tweak permissions so you don't need is_superuser powers anymore.
- Update BossoBillingPoster for posting backup data counts to (internal)
Bosso system.

~~~~~~~~~~~~~~~~~~~

**Web interface**

- Show "time since last backup" in listing, instead of just OK/FAIL.

**Tasks**

- Add locking to dutree scanner, so the filesystem isn't raped. Only do
one dutree scan at a time.
- Change scheduler: jobs are now scheduled ahead of time by deducting
the expected duration.
- Fix rsync issue when remote directory permissions are wrong
(unreadable by user). In that case, the download (as root user) would
succeed, but later changes would fail locally (planb user).

**Other**

- Change schema, removing unnecessary weekly/monthly booleans.
- Fix ``total_size_mb`` in report, which was too large.
- Improve ``breport`` command to output to stdout by default.

~~~~~~~~~~~~~~~~~~~

**Web interface**

- Show job failures in hostconfig detail view.
- Reduce clutter in hostconfig list view, using smaller items and less
clutter.
- Show average run time, instead of last run time.

**Other**

- Fix bug with sending of breport emails.
- Use git version for pip-install if available; add makefile for quick
commands.
- Update qcluster argv so it's still considered busy while doing the
dutree scan.

~~~~~~~~~~~~~~~~~~~

**Web interface**

- Disallow deletion of non-empty host groups.

**CLI**

- Add ``breport`` command to send out backup reports. See the template
in templates/planb/report_email_body.txt. Note that the report is
still in alpha stage. NOTE: To get e-mail reports as well, you need
to have ``rst2html`` installed.
- Add ``--with-disabled`` to ``confexport`` command to get complete
exports.
- Fix that planb runserver can be used for development (through
PYTHONPATH propagation).

**Other**

- Dependency updates to Django 2.0+.
- Add backup history record keeping, for better logging and averages.

~~~~~~~~~~~~~~~~~~~

- Fix release, this time without pyc files and with wheel package.
