There was a regression in rviz with the previous patch release. We’ve reverted the changes causing the issue and will make a new patch release promptly.
There are currently 6 packages ready to sync and no regressions.
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.
Starting this evening (2021-10-12) we’ll hold all rosdistro PRs for Foxy unless they fix reported regressions. On Wednesday (2021-10-13), we’ll announce the release.
