- An experimental C API client is now available. We are happy to take feedback but be aware the API is subject to change as it gets refined.
- Cluster has changed status from experimental to being a preview feature. Many refinements and bug fixes have been made to cluster in the last few months as a result of significant destructive testing. The API is now stable as of this release and will only change before going GA if a significant issue is found. Support is commercially available.
- Correct implementation of Cubic congestion control implementation to align with spec.
- Add support to the C media driver for session-specific and multi-destination subscriptions (MDS), plus complete the functionality so the C media driver can support
Archive. - Support using
0for port onendpointorcontrolso OS assigns the port without conflict and then make it available onPublicationorSubscriptionvia each getting a newlocalSocketAddresses()method. Local socket addresses also get their own counters. - Reduced CPU time spent scanning for loss in Java and C drivers so they can scale to a larger number of connections.
- Apply consistent approach to merge window for
ReplayMerge, Archive replication, and Cluster catchup. - Add the ability to stop a recording by recording identity when the recording id is known.
- Use CRC if configured and any possible data to help recover last fragments in a recording that may straddle a OS page after an unclean Archive shutdown.
- Support common short name alias for idle strategies in config for both Java and C media driver such as
noop,spin,yield, andbackoff. - Update false sharing protection to support Java 15 class layout and add it to
ExclusivePublication. - Improve Java and C++ samples so they are up to date and give more consistent performance numbers.
- Java client close operations for publications, subscriptions, and counters now happen asynchronously so the client does not wait for acknowledgement. This allows for more rapid close of resources.
- Add notifications for client heartbeat counters becoming available and unavailable so Aeron clients can be tracked.
- Allow for race in creating a new recording in catalog and first segment being written which can happen when a replay is set up right after a recording starts.
