+  - relnote: Unsupported `ALTER TABLE` command on materialized views is no longer replicated.
+    component: BDR
+    details: |
+      Replication no longer becomes stuck when the command is issued.

+  - relnote: Fixed a bug where `bdr_init_physical` stopped responding when `synchronous_commit` is set to `remote_write/remote_apply`.
+    component: BDR
+    details: |
+      `bdr_init_physical` disables synchronous replication on a new node by resetting `synchronous_standby_names` to an empty string. A warning message reminds you to set `synchronous_standby_names` as needed.

+    impact: Medium
+  - relnote: Fixed a bug to handle additional replication sets on witness nodes.
+    component: BDR
+    details: |
+      The witness node now only cares about the top replication set and thus allows it to miss replications sets and not error out.

+  - relnote: Fixed autopatition task scheduling.
+    component: BDR
+    details: |
+      To improve reliability, shuffle the scheduling of autopartition tasks. This way, tasks that are prone to failure won't consistently impact the success of other tasks.
