Preparing for final Crystal sync and patch release: 2019-12-12

It’s hard to believe that Crystal has been out for an entire year. But now it’s time to say farewell!
This will be the last sync and patch release for ROS 2 Crystal Clemmys.

Because Apple and Homebrew have dropped support for macOS Sierra, we will not be providing a macOS binary for this final Crystal patch release.

We’re using a GitHub project board to track the release status.
If there is a pull request that you want included in the patch release you can propose it on the release tracking issue.
There are also new packages from the community ready for sync:

If you find a regression when testing, please report it upstream and leave a comment here so we can track it leading up to the sync.

Please get your releases in for this sync as soon as you are able, and on 2019-12-10 we’ll hold all rosdistro PRs unless they fix reported regressions.

Crystal’s final sync is live on the testing server. As long as no regressions are reported we’ll sync tomorrow as planned.

The release is out.
