Yeah, once Galactic was branched from Rolling, Rolling itself became a lot more volatile as the pending disruptive changes all merged in at once. I’ll open up a Preparing… thread shortly for a sync ASAP.
Since the ROS build farm uses the testing repositories for all of its Dev and PR jobs, I recommend that most CI systems follow that lead, but it doesn’t absolve the need to maintain the syncs to main for Rolling and a regular schedule makes sense but in order to make it easier to fit within a work-week (as the 1st or 15th may fall fall on a weekend day) I’ll aim for syncs to rolling to happen on the first and third Thursday of each month. If, in the future Rolling syncs to main are automated we can figure out if moving to a day-of-month rather than day-of-week based schedule makes sense.
