Full Changelog: v0.28.1...v0.28.2

v0.29.1

• Add ForceRESP2 option for RedisShardConfig. If set to true forces using RESP2 protocol for communicating with Redis. By default, Redis client tries to detect supported Redis protocol automatically trying RESP3 first.

v0.29.0

This release contains several breaking changes.

• Removing client protocol v1 and all related parts, see #275 for more details. If you are using the latest SDK versions - this should not affect you.
• Possibility to configure history meta TTL on a per-channel level, #264. This is optional and global history TTL value may be set over Config.HistoryMetaTTL option. By default, it's 30 days.
• One shot encode/decode for control proto #263. Note that with this change all nodes in your Centrifuge cluster should be v0.29.0 to work properly. Do not mix nodes based on Centrifuge < v0.29.0 with nodes based on Centrifuge v0.29.0.
• Add client level ping config, remove AppLevelPing #286 by @bfwbbrj.

v0.28.0

• Centrifuge v0.28.0 comes with an updated Redis Engine implementation based on rueian/rueidis library. Allocation efficiency and throughput of Redis Broker and PresenceManager were improved in both standalone and Cluster Redis setups. See #262 and blog post Improving Centrifugo Redis Engine throughput and allocation efficiency with Rueidis Go library for the reasoning and numbers behind.
• Work on a better observability and possibility to protect client protocol from misusing: Centrifuge now has CommandReadHandler and CommandProcessedHandler. These handlers are only available for client protocol v2, client protocol v1 will be removed soon. While it's not removed DisableProtocolVersion1 global var may be used to disable possibility for clients to connect to server with ProtocolVersion1.
• Client now can't send infinite number of pongs to the server, only one pong after receiving ping is allowed
• Client now can't send any command to the server after getting error in Connect command
• Disconnect client if it sends async message (using Send method) to the server while MessageHandler not set
• Possibility to dramatically reduce server CPU usage in case of sending many messages towards individual connections (it may be up to 5x reduction depending on message rate). This is possible with new options of ConnectReply: WriteDelay, ReplyWithoutQueue, MaxMessagesInFrame, QueueInitialCap which allow tweaking Centrifuge message write loop. See #270 for more details.
• Several internal optimizations in client protocol to reduce memory allocations a bit.
• More human-readable tracing logging output (especially in Protobuf protocol case). On the other hand, tracing log level is much more expensive now. We never assumed it will be used in production – so seems an acceptable trade-off.
• Update centrifuge-js version in all examples

# summary
v0.28.0 is a valid semantic version for this release.

v0.28.0-rc.3

v0.28.0-rc.3 contains fix of decoding large client protocol messages. The bug was introduced by v0.28.0-rc.2. This could lead to client disconnections in v0.28.0-rc.2

v0.28.0-rc.2

One more release candidate for Centrifuge v0.28.0. See changelog about v0.28.0 to find out details of upcoming release.

v0.28.0-rc.2 contains an important fix compared to v0.28.0-rc.1 which relates to new Redis Engine we introduced in v0.28.0-rc.2: slow down subscription dissolver workers while Redis PUB/SUB is unavailable. This solves a high CPU usage which may happen while Redis PUB/SUB is unavailable and last client unsubscribes from some channel.
