+  - POST ``/api/v4/users/{user_id}/demote`` now returns 400 when ``user_id`` is a bot account; bot accounts cannot be converted to guests.
+  - Improved memory usage and performance when processing images (resizing, thumbnails, and orientation correction).
+  - Plugins using the Shared Channels APIs can now register multiple remote connections by calling ``RegisterPluginForSharedChannels`` with different ``SiteURL`` values, enabling use cases like multiple outbound transports or bridging to multiple external servers. A new ``UnregisterPluginRemoteForSharedChannels`` method allows removing a single remote without affecting others. Existing single-remote plugins continue to work without changes.
+  - Fixed an issue where file attachments synced over a shared channel through a plugin (using the ``OnSharedChannelsAttachmentSyncMsg`` / ``ReceiveSharedChannelAttachmentSyncMsg`` plugin API pair) were stored on the receiving server but did not appear in the corresponding post, because the saved FileInfo was given a new ID instead of preserving the sender's file ID referenced by the post.
+  - Plugin API's for Shared Channel sync (``ReceiveSharedChannelSyncMsg`` and ``ReceiveSharedChannelAttachmentSyncMsg``) are now order-tolerant and idempotent: plugin remotes can now deliver a post and its file attachments in either order or concurrently, and at-least-once redeliveries no longer produce duplicate FileInfo rows.
