0.71

• Update to Agrona 1.6.0, SBE 1.19.0, and Aeron 1.29.0.
• Add support for not incrementing sequence numbers when a business reject of a message with a null ref seq id is received.
• Don't return positive action count from FixLibrary when there's only disconnected sessions.
• Ensure FixEngine.close() can be executed once even if exception is thrown.

0.70

• Extend unbind operation with optional disconnect and logout for sessions
• Allow more tolerant time-parsing
• Add ability to send resend requests for previous UUID in iLink3

• Accept exceeding gap range in resend.
• Add ref tag id to more reject messages.
• Improved FIX spec compliance: Send logout after rejected Logon message.
• Improved FIX spec compliance: increment sequence numbers on rejected messages.
• Fix bug where slow consumer replay messages could get fragmented.

0.69

• Improve prune operation logging
• Make replay position buffer size configurable
• Fix bug where a freeze could happen in IndexedPositionWriter.indexedUpTo during startup
• Fix bug where the sequence index may not increment due to message that are sent when offline

0.68

• Add a log tag and logging for pruning operations
• Add support for detecting sequence number gaps from sequence messages are detected in iLink3
• Fix bug where the message timing handler didn't get callbacks for messages that are from slow consumers.
• Fix issue where free recording ids aren't counted as part of the prune operation.

0.67

• iLink3 Improvements
• Add human readable error messages for iLink3 error codes
• Expose whether a message can be sent or not
• Add a callback for receiving remote disconnects.
• Handle sequence gaps within retransmits
• FIX Improvements
• Add a counter to monitor concurrent replays in flight
• Add a limit on the number of concurrent replays from one session.
• Ensure more prompt cleanup of replay operation for a session that has had a disconnect
• Fix bug where resend requests of disconnected sessions that were in flight at the point of disconnect wouldn't be ignored.
• Add a sequence number parameter to the message timing handler

0.66

• Add callback so users can get per message timings to the TCP layer.
• Improved iLink3 protocol compatibility and logging
• Fix bug where last message within an iLink3 retransmit isn't handed off to the application
• Fix offset bug when receiving FIX messages
• Close scanner in FixArchivePrinter when not in follow mode

0.65

• fix bug where calling FixEngine.resetSequenceNumber() for every session id could result in the prune operation not pruning the archive
• fix bug where Session.trySendSequenceReset() could result in the prune operation not pruning the archive
• fix bug where the sequence index of received messages after a logon exchange within the same TCP connection isn't incremented. Also ensures that Session.tryResetSequenceNumbers() also enables the pruning of old sequence numbers
• fix bug where initiator sessions couldn't reconnect in sole library mode.
• remove leaked counters when they are closed to avoid memory leak

0.64

• Fix bug where gateway could hang on startup
• Fix race where acceptor socket could get unbound in sole library mode
