+
+GerritForge has decided to [change the license to BSL](https://gitenterprise.me/2025/09/30/re-licensing-gerritforge-plugins-welcome-to-gerrit-enterprise/)
+therefore the Apache 2.0 version of this plugin is deprecated.
+The recommended version of the cached-refdb plugin is on [GitHub](https://github.com/GerritForge/cached-refdb)
+and the development continues on [GerritHub.io](https://review.gerrithub.io/admin/repos/GerritForge/cached-refdb,general).

+# Plugin to cache Git repository's access to refdb (DEPRECATED)
When [Serialize AccountCache series](https://gerrit-review.googlesource.com/c/gerrit/+/260992)
was introduced it simplified the cache eviction by always reaching out to JGit
