Hi all,

On 2025-04-08T06:59:00Z we will freeze all RMW related packages in preparation for the upcoming Kilted Kaiju release on May 23, 2025.

Once this freeze goes into effect, we will no longer accept additional features to RMW packages, which includes rmw_fastrtps, rmw_cyclonedds, rmw_connextdds, rmw_zenoh; as well as their vendor packages, Fast-DDS, Fast-CDR , cyclonedds, iceoryx and zenoh_cpp.

Bug fixes will still be accepted after the freeze date.

You may find more information on the Kilted Kaiju release timeline here: ROS 2 Kilted Kaiju (codename ‘kilted’; May, 2025).

After some final changes and checks, RMW packages in Rolling (soon to be Kilted) will now accept only bugfixes and are considered feature-frozen.

These repositories will reopen for feature development when Kilted branches from Rolling on April 21, 2025. As @mjcarroll mentioned, you can find more information on the Kilted Kaiju release timeline here: ROS 2 Kilted Kaiju
