• [Java] Fix IllegalStateException that could exist for an MDS subscription on the rapid recycling of ReplayMerge operations.
• [C] Align ring buffer implementations and feature set with Java.
• [Java] Make sure that C and Java are aligned on resend window. Re-instate the max message length being accounted in the bottom of the resend window for Java.
• Add duty cycle duration tracking to all agents across all modules.
• [C++] Improve efficiency by reducing the number of copy operations for fragment assembly when a stream has many fragmented messages.
• [C] Default to CLOCK_REALTIME for send/receive timestamps.
• [Java] Add setters for send/receive timestamp clocks to the MediaDriver.Context.
• Fix handling of fragment assemble when reliable=false is set for a channel and loss occurs.
• Improve handling of short sends on MDC publication to backoff from overloading a socket.
• Add round-robin facility to MDC publication for increased fairness.
• [Java] Publish aeron-test-support package as a JAR.
• [Java] Downgrade "unknown replay" errors to warnings for cluster catchup.
• [Java] Add appVersion to event logging for consensus module and check for correct app version when replaying log.
• [Java] Prevent timeout warnings with cluster dynamic nodes and log replication.
• [Java] Add cluster dynamic join state change logging events.
• Add counters for the number of receivers in min and tagged flow control strategies.
• [Java] Avoid race unmapping buffers on concurrent close of media drivers.
• Modify flow control strategies to have new method for when elicited setups are sent and add counters manager to init methods. Modify Min and Tagged flow control to use setup snd-lmt as min position until timeout or receiver added on SM.
• [Java] Account for possible padding in log buffer when checking for bottom resend window for retransmits.
• [C] Flush output when printing configuration.
• [C] Raise warning on failure to setup media timestamping.
• [Java] Update recordingId on any signal with a valid recording id when handling signals for snapshot replication.
• [Java] When attempting ClientSession.tryClaim, ensure that there is enough buffer space when returning a mocked offer for a follower.
• [C] Ensure publication image is released before it it freed.
• [C] Fix scanf that could result in buffer overflow when parsing HTTP for configuration.
• [Java] Change default cluster session timeout from 5 to 10 seconds.
• Prevent receiver joining min/tagged flow control if they are more than a window behind.
• [C] Add sample for working with large messages.
• [Java] Add logging event for appending a cluster session close.
• Upgrade to BND 6.3.1.
• Upgrade to Mockito 4.6.1.
