librdkafka v2.11.1 is a maintenance release:

• Made the conditions for enabling the features future proof (#5130).
• Avoid returning an all brokers down error on planned disconnections (#5126).
• An "all brokers down" error isn't returned when we haven't tried to connect to all brokers since last successful connection (#5126).

Fixes

General fixes

• Issues: [#4948], [#4956]. Made the conditions for enabling the features future proof, allowing to remove RPC versions in a subsequent Apache Kafka version without disabling features. The existing checks were matching a single version instead of a range and were failing if the older version was removed. Happening since 1.x (#5130).

• Issues: [#5142]. Avoid returning an all brokers down error on planned disconnections. This is done by avoiding to count planned disconnections, such as idle disconnections, broker host change and similar as events that can cause the client to reach the "all brokers down" state, returning an error and since 2.10.0 possibly starting a re-bootstrap sequence. Happening since 1.x (#5126).

• Issues: [#5142]. An "all brokers down" error isn't returned when we haven't tried to connect to all brokers since last successful connection. It happened because the down state is cached and can be stale when a connection isn't needed to that particular broker. Solved by resetting the cached broker down state when any broker successfully connects, so that broker needs to be tried again. Happening since 1.x (#5126).
