+- Update to 1.41.1
+  Due to the two security issues highlighted below, server
+  administrators are encouraged to update Synapse. We are not aware
+  of these vulnerabilities being exploited in the wild.
+
+  - Security advisory
+    The following issues are fixed in v1.41.1.
+
+    - GHSA-3x4c-pq33-4w3q / CVE-2021-39164: Enumerating a private
+      room's list of members and their display names.
+
+      If an unauthorized user both knows the Room ID of a private
+      room and that room's history visibility is set to shared,
+      then they may be able to enumerate the room's members,
+      including their display names.
+
+      The unauthorized user must be on the same homeserver as a
+      user who is a member of the target room.
+
+      Fixed by 52c7a51cf.
+
+    - GHSA-jj53-8fmw-f2w2 / CVE-2021-39163: Disclosing a private
+      room's name, avatar, topic, and number of members.
+
+      If an unauthorized user knows the Room ID of a private room,
+      then its name, avatar, topic, and number of members may be
+      disclosed through Group / Community features.
+
+      The unauthorized user must be on the same homeserver as a
+      user who is a member of the target room, and their homeserver
+      must allow non-administrators to create groups
+      (enable_group_creation in the Synapse configuration; off by
+      default).
+
+      Fixed by cb35df940a, #10723.
+
+  - Bugfixes
+    - Fix a regression introduced in Synapse 1.41 which broke email
+      transmission on systems using older versions of the Twisted
+      library. (#10713)
