 ## Bugfix Releases
 
+### 2.12.7 {#2.12.7}
+
+* [Issue 4930](https://bugs.chromium.org/p/gerrit/issues/detail?id=4930)
+Allow submit of merge commit of a branch that is not a change.
+
+  A regression introduced in 2.12.6 prevented a merge commit from being
+  submitted if it merges a branch that is not associated to a change.
+
+* Avoid unnecessary group visibility checks in list-groups REST endpoint.
+
+  The list-groups REST API call checked group visibility even for those
+  groups which were filtered out. In a system with 10-20K of groups, this
+  could cause 30-60 seconds delay when checking if the current user can see
+  a group.
+
+* Download Commands plugin: Fix HTTP clone command inconsistency.
+
+  When cloning a project using HTTP schema, the `/a` in the URL was added
+  only when choosing to clone without the commit hook. Now the URL is the
+  same in both cases.
