Special instructions

The Alembic configuration file has changed to use the Python path of the migrations.
In order to run the new migrations, you should ensure your alembic.ini has
script_location = bodhi:server/migrations.

Dependency changes

The client formally depends on iniparse now. It needed this before but the dependency was
undocumented (ddf47eb).
Bodhi no longer uses or requires webhelpers. RSS feeds are now generated by feedgen, a new
required dependency.
Bodhi no longer uses or requires bunch.

The CLI now prints a helpful hint about how to use koji wait-repo when creating or editing a
buildroot override, or when a query for overrides returns exactly one result (#1376).
Bodhi now uses connection pooling when making API requests to other services (#1753).
The bindings now conditionally import dnf (#1812).
It is now possible to query for Releases by a list of primary keys, by using the querystring
ids with the releases/ API.
Builds now serialize their release_id field.
It is now possible to configure a maximum number of mash threads that Bodhi will run at once,
which is handy if the new Pungi masher has been mean to your NAS. There is a new
max_concurrent_mashes setting in production.ini, which defaults to 2.
There is now a man page for bodhi-clean-old-mashes.
The documentation was reorganized by type of reader (14e81a8).
The documentation now uses the Alabaster theme (f15351e).
The CLI now has a --arch flag that can be used when downloading updates to specify which
architecture is desired (6538c9e).
Bodhi's documentation now includes an administration section which includes documentation
on its various settings (310f56d).

#Bugs

Bodhi now uses the correct comment on critical path updates regarding how many days are required
in testing (#1361).
All home page update types now have mouseover titles (#1620).
e-mail subjects again include the version of the updates (#1635).
The bindings will re-attempt authentication upon captcha failures (#1787).
The formatting is fixed on mobile for the edit/create update form (#1791).
The "Push to Stable" button is now rendered in the web UI on batched updates (#1907).
Do not fail the mash if a changelog is malformed (#1989).
bodhi-dequeue-stable no longer dies if it encounters updates that can't be pushed
stable (#2004).
Unreachable RSS Accept-header based redirects were fixed (6f3db0c).
Fixed an unsafe default in bodhi.server.util.call_api() (9461b3a).
Bodhi now distinguishes between testing and stable when asking Greenwave for gating decisions
(6d907a7).
The CLI now renders the correct URL for updates without aliases (:commit:caaa0e6e).

Development improvements
^^^^^^^^^^^^^^^^^^^^^^^^

The database migrations are now shipped as part of the Python distribution
(#1777 <https://github.com/fedora-infra/bodhi/pull/1777>_).
The developer docs pertaining to using virtualenvs have been corrected and improved
(:issue:1797).
The test_utils.py tests now use the BaseTestCase, which allows them to pass when run by
themselves (:issue:1817).
An obsolete mash check for symlinks was removed (:issue:1819).
A mock was moved inside of a test to avoid inter-test dependencies (:issue:1848).
Bodhi is now compliant with flake8's E722 check (:issue:1927).
The JJB YAML file is now tested to ensure it is valid YAML (:#1934).
Some code has been prepared for Python 3 compatibility (d776356).
Developers are now required to sign the DCO (34d0ceb).
There is now formal documentation on how to submit patches to Bodhi (bb20a0e).
Bodhi is now tested by Fedora containers in the CentOS CI environment (36d603f).
Bodhi is now tested against dependencies from PyPI (1e8fb65).
The development.ini.example file has been reduced to a minimal form, which means we no longer
need to document the settings in two places (2b7dc4e).
Bodhi now runs CI tests for different PRs in parallel (6427309).
Vagrantfile.example has been moved to devel/ for tidiness (21ff2e5).
It is now easier to replicate the CI environment locally by using the devel/run_tests.sh
script.
Many more docblocks have been written across the codebase.
Line test coverage is now at 93%.
