+
+
+Internal changes
+----------------
+
+* Remove the MonadMask instance for AppT in Brig (#2259)
+
+* Remove the MonadUnliftIO instance for the app monad in Brig (#2233)
+
+* Bump hsaml2 version (#2221)
+
+* Fix: cabal-install-artefacts.sh fails if not run from root of wire-server (#2236)
+
+* Fix: pushing to cachix not working (#2257)
+
+* Cannon has been fully migrated to Servant (#2243)
+
+* Refactor conversation record and conversation creation functions. This removes a lot of duplication and makes the types of protocol-specific data in a conversation tighter. (#2234)
+
+   - Move conversation name size check to `NewConv`
+   - Make the `NewConversation` record (used as input to the data
+     function creating a conversation) contain a `ConversationMetadata`.
+   - Implement all "special" conversation creation in terms of a general `createConversation`
+   - Move protocol field from metadata to Conversation
+   - Restructure MLS fields in Conversation record
+   - Factor out metadata fields from Data.Conversation
+
+* Fix Docs: real-world domain used in examples (#2238)
+
+* The `CanThrow` combinator can now be used to set the corresponding error effects in polysemy handlers. (#2239)
+
+* Most error effects in Galley are now defined at the granularity of single error values. For example, a handler throwing `ConvNotFound` will now directly declare `ConvNotFound` (as a promoted constructor) among its error effects, instead of the generic `ConversationError` that was used before. Correspondingly, all such fine-grained Galley errors have been moved to wire-api as constructors of a single enumerated type `GalleyError`, and similarly for Brig, Cannon and Cargohold. (#2239)
+
+* Add a column for MLS clients to the Galley member table (#2245)
+
+* Pin direnv version in nix-hls.sh script (#2232)
+
+* nginx-ingress-services chart: allow for custom challenge solvers (#2222, #2229)
+
+* Remove unused debian Makefile targets (#2237)
+
+* Use local serial consistency for Cassandra lightweight transactions (#2251)
