We are migrating GitLab's container registry to the next-generation platform, which features online garbage collection and improves the efficiency of many registry operations. During the migration, the container registry will be in read-only mode for approximately 1 hour, beginning March 18 at 13:00. Outside of this brief maintenance window, the service will function normally.
Releases are based on Git tags and mark specific points in a project's development history. They can contain information about the type of changes and can also deliver binaries, like compiled versions of your software.
