 ##### Other Fixes
 
+* [Issue 10512](https://bugs.chromium.org/p/gerrit/issues/detail?id=10512):
+Include project name in change URL in `Reviewed-on:` footer in commit message.
+
+* [Issue 10500](https://bugs.chromium.org/p/gerrit/issues/detail?id=10500):
+Fix injection of `UrlFormatter` in plugins.
+
+  In version 2.16.1 the binding of the `UrlFormatter` interface was changed to
+  use `DynamicItem`, but several classes were still injecting it directly. As a
+  result, when such a class got injected in a plugin, the plugin would fail to load.
+  It was also not possible for a plugin to provide an alternative implementation of
+  `UrlFormatter`, and the `DefaultChangeReportFormatter` always used the
+  `DefaultUrlFormatter`.
+
+* [Issue 10488](https://bugs.chromium.org/p/gerrit/issues/detail?id=10488):
+Fix listing of GPG public keys.
+
+  The GPG public keys were truncated in the output of the GPG key REST API
+  endpoints.
+
+* Fix authentication for LFS over SSH.
+
+* Add logging of prolog rule reduction limits.
+
+  The configured values of `rules.reductionLimit` and `rules.compileLimit`
+  are logged at INFO level at server startup, and the effective value applied
+  to a predicate is logged at DEBUG level.
+
 * Improve error message when JRE cannot be found during site start.
 
 * Suggest `--no-edit` option when `Change-Id` line is missing.
