• Removing AckMode #31
• (High priority) broker-reader-writer pattern overhaul to allow shorter connection error propagation Proper error handling for connection interruption #29
• (High priority) Add context to RPC impl on the server side #28
• Remove DEFAULT_RPC_PATH to avoid confusion #35
• (Mid priority) migrate to tracing and distributed tracing with opentelemetry #26
• (Mid priority) adding support for HTTP integration with poem
• (Mid priority) drop support for HTTP integration with actix-web. Supporting actix-web requires essentially writing a lot of duplicated code due to the fact that it keeps using an old tokio runtime
