2.3.0 not secure

  - Support for older browsers has been hopefully temporarily broken due to frontend changes in progress. Notably, Internet Explorer 11 is not supported in this release.

  made private. Users of these undocumented APIs are encouraged to file bugs to
  get them exposed.
  - Removed support of old slave APIs from pre-0.9 days. Using old APIs may fail
  silently. To avoid weird errors when upgrading a Buildbot installation that
  may use old APIs, first upgrade to to 1.8.0 and make sure there are no
  deprecated API warnings.

1.0.0 not secure

  Despite the major version bump, Buildbot 1.0.0 does not have major difference with the 0.9 series.
  1.0.0 is rather the mark of API stability.
  Developers do not foresee a major API break in the next few years like we had for 0.8 to 0.9.
  Starting with 1.0.0, Buildbot will follow versioning methodology.
  Bug fixes
  - Cloning :bb:step:`Git` repository with submodules now works with Git < 1.7.6
  instead of failing due to the use of the unsupported ``--force`` option.
  - :bb:chsrc:`GitHub` hook now properly creates a change in case of new tag or
  new branch. :bb:chsrc:`GitHub` changes will have the ``category`` set to

  - The ``owners`` property now includes people associated with the changes of
  the build (:issue:`3904`).
  - The repo source step now syncs with the ``--force-sync`` flag which allows
  the sync to proceed when a source repo in the manifest has changed.
  - Add support for compressing the repo source step cache tarball with ``pigz``,
  a parallel gzip compressor.

  but the last one :issue:`3813`.
