 ## Bugfix Releases
 
+### 2.13.9 {#2.13.9}
+
+* [Issue 6176](https://bugs.chromium.org/p/gerrit/issues/detail?id=6176):
+Fix internal server error when old patch set is not found.
+
+* [Issue 6605](https://bugs.chromium.org/p/gerrit/issues/detail?id=6605):
+Fix searching for change by Change-Id triplet when project name matches Change-Id pattern.
+
+  For projects whose name matched the Change-Id pattern, i.e. named something
+  like `iabcde`, it was not possible to search for changes using the Change-Id
+  triplet `project~branch~changeId`.
+
+* [Issue 3345](https://bugs.chromium.org/p/gerrit/issues/detail?id=3345):
+Preserve line endings in inline editor.
+
+  When a file with Windows line endings was edited all the line ending
+  characters were replaced by Unix style line endings.
+
+* Fix line wrapping in inline editor.
+
+  The line wrapping preference was respected for the diff screens, but not
+  for the inline editor.
+
+* Fix cyclic dependency when using `site_path` from `system_config` table.
+
+  The starting mode where `site_path` is not specified (as a system property)
+  and Gerrit first connects to the database using the ReviewDb JNDI property
+  from the servlet container was broken since version 2.13 due to a cyclic
+  dependency in Guice bindings.
+
+* Extend upload validation interface to allow listening to negotiation start.
+
+  This can be used to check rate limits for fetch requests. Rate limits
+  should be checked before git transport negotation starts to avoid
+  unnecessary work in case the limit is already reached.
+
+* Allow to set Jetty HTTPD socket timeout.
+
+  A new setting [`httpd.idleTimeout`](http://gerrit-documentation.storage.googleapis.com/Documentation/2.13.9/config-gerrit.html#httpd.idleTimeout)
+  makes the Jetty HTTPD socket timeout configurable so to tailor the socket
+  and thread consumption to the needs of setups with different latencies and
+  bandwidth.
+
+* Add metrics for reviewer suggestion.
+
+  The metrics `reviewer_suggestion/query_accounts` and `reviewer_suggestion/query_groups`
+  record the latency of querying accounts and groups for reviewer suggestion.
+
 ### 2.13.8 {#2.13.8}
 
 * Improvements in "reviewed" flags cache
