 ## Bugfix releases
 
+### 3.13.3
+
+* Bug Fixes
+
+  * [Issue 481248236](https://issues.gerritcodereview.com/issues/481248236):
+    Fix missing label values for closed changes.
+
+    Fix regression caused by the refactoring of the labels for submit records
+    causing votes to disappear from history of closed changes.
+
+  * [Issue 470709366](https://issues.gerritcodereview.com/issues/470709366):
+    Use the correct `NoOp` label function in the label builder UI.
+
+    Passing the incorrect `Noop` value caused a `400 Bad Request` error
+    when generating new labels from the web interface.
+
+  * [Change 547446](https://gerrit-review.googlesource.com/c/gerrit/+/547446):
+    Relax the regular expression for base64 images in comments.
+
+    The regex now correctly identifies a broader range of valid Markdown
+    base64 image strings, including those with whitespace, uppercase
+    schemes, or extra MIME parameters.
+
+* UI Fixes
+
+  * [Change 547481](https://gerrit-review.googlesource.com/c/gerrit/+/547481):
+    Fix undefined property errors in `gr-checks-runs` and `gr-create-change-dialog`.
+
+    Resolved potential runtime crashes by adding guard clauses and providing
+    safe default values for UI properties.
+
+  * [Change 547443](https://gerrit-review.googlesource.com/c/gerrit/+/547443),
+    [Change 547463](https://gerrit-review.googlesource.com/c/gerrit/+/547463),
+    [Change 547462](https://gerrit-review.googlesource.com/c/gerrit/+/547462),
+    [Change 547465](https://gerrit-review.googlesource.com/c/gerrit/+/547465),
+    [Change 547441](https://gerrit-review.googlesource.com/c/gerrit/+/547441):
+    Fix infinite update loops and redundant re-renders in multiple UI components.
+
+    Update logic for several components (diff view, avatar stack, dropdown
+    lists, headers), preventing Lit state management loops and improving performance.
+
+  * [Change 547464](https://gerrit-review.googlesource.com/c/gerrit/+/547464),
+    [Change 547442](https://gerrit-review.googlesource.com/c/gerrit/+/547442):
+    Fix Lit rule violations in multiple UI components.
