Hello,

The v2025.04 release of the OpenAMP project repositories is scheduled for the end of next month.

Please note that the feature freeze will take effect on April 18th. After this date, only bug fixes will be accepted until the release.

To ensure sufficient time for the review process, please submit your pull requests at least two weeks before the feature freeze date.

Thanks and regards, Arnaud Pouliquen
