Varnish Controller 7.4.1 Release

Published March 13, 2026.

This release is only for the new feature keep-invalidations. Brainz, apigw, vcli and UI need to be updated for this release in order to get the keep-invalidation feature to work.

Invalidations can now be marked with keep so that they are kept and not automatically removed. They can then be re-executed at a later time. Kept invalidations needs to be manually removed.
Fixed a bug where the permission for purger tokens was missing in the UI.
New nats-server, version 2.12.5.

See Varnish Controller Changelog for more details on the changes and the upgrade notes for more details on how to upgrade.
