Important Update: Aeron is moving to a new GitHub organisation

Aeron is moving to a new GitHub organisation following its adoption by Adaptive in 2022. This transition marks a significant milestone in Aeron's journey, ensuring continued innovation and support for the world's leading low-latency message transport system.

You can find the new Aeron, SBE and Agrona repositories and all related resources at aeron-io.

All links to the previous repository location are automatically redirected to the new location.
However, to avoid confusion, we recommend updating any existing local clones to point to the new repository URL. You can do this by using git remote on the command line:

git remote set-url origin NEW_URL

Thank you for your continued support and contributions to the Aeron Open Source project.

Breaking changes

[Java] Agrona upgrade brings breaking changes. See 2.0.0 release notes.

Note: --add-opens java.base/jdk.internal.misc=ALL-UNNAMED JVM option must be specified in order to run Aeron. In addition to --add-opens java.base/java.util.zip=ALL-UNNAMED that is required to running the Aeron Archive.

Noteworthy Changes

Detect and terminate dormant Archive clients.

Archive will now send periodic heartbeat messages to each connected Archive client. By default it is done once per second and can be configured via aeron.archive.session.liveness.check.interval property or programmatically via io.aeron.archive.Archive.Context#sessionLivenessCheckIntervalNs(long) method. If it detects that it cannot send such a message for more than a connection timeout (i.e. aeron.archive.connect.timeout, defaults to 5 seconds) then it will close the corresponding control session which will cause such Archive client to disconnect.
Eliminate interference between Archive clients.
C/C++ Wrapper implementation of the Archive client APIs.

In terms of feature completeness and stability, they are still marked experimental, as there's a small chance some of the functions might change as the feature is hardened. Furthermore, a number of the async APIs have yet to be implemented.
Fix duplicate service messages during failover/restart when using multiple services in Cluster.

When service messages are being sent from multiple services, these can be enqueued in different orders. This means during failover/restart pending messages can be skipped or duplicated when a new leader is elected.

Upgrade procedure: Those affected will need to do a clean shutdown (with a snapshot) and restart the whole cluster with the fix.
Invalidate Standby snapshots.

When invalidating latest snapshot both normal and Standby snapshots are taken into account. In order to prevent invalidated snapshots from being re-downloaded from the Standby node upon recovery.
New log events for NAK messages sent and received.

NAK_RECEIVED logging event was added when a NAK request is received by the sender. An existing SEND_NAK_MESSAGE event was renamed to NAK_SENT and logs a NAK message being sent by the receiver.
Prevent client process crashing by a pathologically slow consumer.

If a call to Controlled/FragmentHandler#onFragment blocks for disproportionate amount of time, i.e. long enough for an Image to become unavailable. Then the corresponding log buffer will freed by the client conductor thread. Any further access to the log buffer will cause the client process to segfault. The Image was updated to prevent any further access once it was closed.
