 ## What's changed
 
-Centrifugo v5.4.2 comes with useful improvements and fixes.
-
 ### Improvements
 
-* [Raw mode for Nats broker](https://centrifugal.dev/docs/server/engines#nats-raw-mode) – in this mode Centrifugo just consumes core Nats subjects and does not expect any Centrifugo internal wrapping. Clients just get a raw payload from Nats, which may be useful if you have Nats and want to expose subjects to client-side real-time connections with the help of Centrifugo.
-* Option to [use wildcard subscriptions](https://centrifugal.dev/docs/server/engines#nats_allow_wildcards) with Nats broker. allows subscribing to [wildcard Nats subjects](https://docs.nats.io/nats-concepts/subjects#wildcards) (containing `*` and `>` symbols). This way client can receive messages from many channels while only having a single subscription.
-* Support configuring [client TLS in GRPC proxy](https://centrifugal.dev/docs/server/proxy#proxy_grpc_tls), here we started migration to [unified TLS config object](https://centrifugal.dev/docs/server/tls#unified-tls-config-object) – using it here for configuring GRPC client TLS. See more details about revisiting TLS configuration in [this issue](https://github.com/centrifugal/centrifugo/issues/831). TLS object is also supported for GRPC client in [granular proxy configuration](https://centrifugal.dev/docs/server/proxy#defining-a-list-of-proxies), see `grpc_tls` field.
-* Support configuring [client TLS in Nats broker](https://centrifugal.dev/docs/server/engines#nats_tls) (for Nats client). Also uses unified TLS config object.
-* [RPC ping extension](https://centrifugal.dev/docs/server/configuration#enable-rpc-ping-extension) to check if connection is alive at any point, measure RTT time.
-* New histogram metric [centrifugo_client_ping_pong_duration_seconds](https://centrifugal.dev/docs/server/observability#centrifugo_client_ping_pong_duration_seconds) to track the duration of ping/pong – i.e. time between sending ping to client and receiving pong from client.
-* More descriptive JWT check error messages [#838](https://github.com/centrifugal/centrifugo/pull/838).
+* Publish Centrifugo Protobuf definitions to [Buf Schema Registry](https://buf.build/product/bsr) [#863](https://github.com/centrifugal/centrifugo/pull/863). This means that to use Centrifugo GRPC APIs it's now possible to depend on pre-generated Protobuf definitions instead of manually generating them from the schema file.
+  * [apiproto](https://buf.build/centrifugo/apiproto/docs/main:centrifugal.centrifugo.api) - definitions of server GRPC API
+  * [unistream](https://buf.build/centrifugo/unistream/docs/main:centrifugal.centrifugo.unistream) - definitions of unidirectional GRPC stream
+  * [proxyproto](https://buf.build/centrifugo/proxyproto/docs/main:centrifugal.centrifugo.proxy) - definitions of proxy GRPC API
+* New integer option `grpc_api_max_receive_message_size` (number of bytes). If set to a value > 0 allows setting `grpc.MaxRecvMsgSize` option for GRPC API server. The option controls the max size of message GRPC server can receive. By default, GRPC library uses 4194304 bytes (4MB).
 
 ### Fixes
 
-* Fix occasional deadlock leading to memory leak, the deadlock was introduced in Centrifugo v5.3.2, see [#856](https://github.com/centrifugal/centrifugo/issues/856). While fixing an issue we've also found a scenario in which the number of clients and subscribers could be incorrect – subscribers could go away, but the subscriber counter is not decremented. Fixed this alongside the deadlock, both issues do not reproduce with our test load anymore.
-* Fix non-working `allow_presence_for_subscriber` option to enable join/leave events when requested by client, see [#849](https://github.com/centrifugal/centrifugo/issues/849)
+* Fix occasional `panic: DedicatedClient should not be used after recycled` panic which could happen under load during problems with Redis connection.
