Release Ionic

[azeey]

During development

• [x] Bump major version of libraries early in the development cycle (use bump_libraries template).
• [ ] Work with artist on logo.

Feature freeze

• [ ] Choose name for next release.
• [ ] Merge each library forward from previous versions
• [ ] Create stable branches off of main
  • [ ] New branch button on branches page (example)
  • [ ] Enable CI for stable branches (example)
  • [ ] Use stable branch jobs in Jenkins view (example part 1 and part 2)
• [ ] Pull requests previously targeted at main:
  • Bug fixes:
    • Retarget to the new stable branch.
    • Label with beta
    • They can be merged until code freeze.
  • Backwards-compatible features, either:
    • Retarget them to the new stable branch (but they can only be merged after the stable release), or
    • Keep targeting main and backport after the stable release.
  • Breaking features:
    • Keep targeting main (i.e. they will be delayed until the next major release)
• [ ] Bump all main branches to the next major version (X.0.0~pre1)
  • [ ] Source code (example)
  • [ ] Add files to gazebodistro (example)
  • [ ] Add aliases to homebrew-simulation (example)
  • [ ] Create new -release repositories (use this script)
  • [ ] Enable nightlies for all main branches on gzdev (example)
  • [ ] Execute the tick-tock's "tock" for deprecations (example)
• [ ] Update Changelog and pre-release libraries as all beta labels are merged.
• [ ] Make collection pre-release after all libraries are pre-released.
• [ ] Update public documentation to install from pre-releases instead of nightlies (example).
• [ ] Change nightlies to pre-release for release branches on gzdev (example)

Code freeze

• [ ] Start T-Shirt campaign
• [ ] Hold tutorial party (example)
• [ ] Update references to the release install instructions
  • [ ] Versions doc https://github.com/gazebosim/docs/blob/master/tools/versions.md
  • [ ] ROS2 Installation https://github.com/gazebosim/docs/blob/master/ros_installation.md
  • [ ] ros_gz README https://github.com/gazebosim/ros_gz/blob/ros2/README.md
• [ ] PRs fixing documentation and critical bugs can be merged and pre-released
• As libraries have all their documentation reviewed:
  • [ ] Make stable releases

Release day

• [ ] Make collection stable release after all libraries are released.
• [ ] Update gazebodistro (example)
• [ ] Make GitHub releases for all the X.0.0 versions (example)
• [ ] Update docs to say release is stable (example)
• [ ] Make announcement

Post-release

• [ ] Enable Jenkins CI for new stable branches (example)
• [ ] Remove pre-release for release branches on gzdev (example)
• [ ] Update all repositories to default to the new stable branches.

If the collection will be officially paired with a ROS 2 distro:

• [ ] Update REP-2000 when ROS 2 distro is added (example)
• [ ] Import stable releases into https://packages.ros.org (example)
• [ ] Add new rosdep keys (example)
• [ ] Bloom-release ros_gz with the new version into Rolling before fork (example)
