 ### 2.14.3 *(In development)* {#2.14.3}
 
+* Load external IDs from primary storage.
+
+  Loading the external ID from the primary storage is safer than finding
+  the account via the account index and then looking up the external ID
+  via the account cache since the account index may be stale.
+
+* [Issue 6853](https://bugs.chromium.org/p/gerrit/issues/detail?id=6853):
+Only attempt to parse `polygerrit` URL parameter on `GET` requests.
+
+  Attempting to parse the `polygerrit` parameter on all requests caused
+  failures when sending a `POST` or `PUT` request to the REST API via `curl`.
+
+* [Issue 6922](https://bugs.chromium.org/p/gerrit/issues/detail?id=6922):
+Fix comparison against edit revision.
+
+* [Issue 6099](https://bugs.chromium.org/p/gerrit/issues/detail?id=6099):
+Set reflog message and identity when merging change.

 Emit an event to the event stream when a vote is removed from a change.

 * Add user who removed reviewer into event that is emitted when a
   reviewer is removed from a change.
 
+* Improve error message when failing to create the first user.
+
+* Allow to run the server without specifying `gerrit.canonicalWebUrl`.
+
+  The only situation where the setting is mandatory is when using OAuth
+  authentication, because the OAuth provider needs to have a fixed callback
+  URL with a single hostname.
+
 * Align group reference from plugin with core group reference.
 
 * Fix `PluginConfig.setGroupReference` method.

   Group reference was not working when inherited from parent project
   config.
 
+* Use `-S` instead of `-s` as alias for `--start` in list branches and tags
+REST API endpoints.
+
+  Using an upper case `-S` makes the API consistent with the other list APIs
+  (changes, groups, projects). This is a breaking change for any clients
+  that use `-s`.
+
+* Allow to configure pool connection settings for patch review store.
+
+  Previously the pool connection settings were hard-coded. In high
+  traffic servers this can cause a bottleneck as the transactions start
+  to be queued when the maximum number of connetions is reached.
+
+  In the [accountPatchReviewDb section](http://gerrit-documentation.storage.googleapis.com/Documentation/2.14.3/config-gerrit.html#accountPatchReviewDb)
+  of the `gerrit.config` file it is now possible to configure the
+  `url`, `poolLimit`, `poolMinIdle`, `poolMaxIdle`, and `poolMaxWait`
+  values.

+* Polygerrit UI

+    * [Issue 6827](https://bugs.chromium.org/p/gerrit/issues/detail?id=6827):
+      Fix loading change screen with a slash following the patch set number.
+
+    * [Issue 6921](https://bugs.chromium.org/p/gerrit/issues/detail?id=6921):
