Activities for group actor

Introduced in GitLab 16.5 with two flags named activity_pub and activity_pub_project. Disabled by default. This feature is an Experiment.

On self-managed GitLab, by default this feature is not available. To make it available, an administrator can enable the feature flags named activity_pub and activity_pub_project. On GitLab.com, this feature is not available. The feature is not ready for production use.

This feature requires two feature flags:

  • activity_pub: Enables or disables all ActivityPub-related features.
  • activity_pub_project: Enables and disable ActivityPub features specific to projects. Requires the activity_pub flag to also be enabled.
