Axon Server 2026.1.0

Announcements
1

We have released a new version of the Axon Server.

Breaking Changes

  • Analytics nodes are no longer supported in Axon Server. Use Axoniq Insights as the recommended alternative. Analytics nodes are removed from replication groups.

  • Axon Server now validates at startup that all configured output locations are writable. If it detects a non-writable location, it will fail to start and log an error message.

New Features

  • Added multi-tier support for DCB contexts.
  • Storage locations for multi-tier contexts can now be configured through both the API and UI.
  • Added support for the SnapshottedDcbEventStore, allowing events and snapshots to be sourced in a single operation.
  • Added support for Message Credits from the Axoniq Platform.
  • Added the option to create an initial administrator user when using Autocluster or Standalone startup modes.
  • The CLI now supports using a properties file with the register-context and update-context commands.
  • Event store migration is now supported for contexts with applied transformations.

Improvements

  • Improved the mechanism for sharing topology information between Axon Server nodes.

  • Enhanced the Search page:

  • Configure a query timeout.

  • Notify users when a query is cancelled due to a timeout.

  • Display a loading indicator while a query is executing.

  • The Overview page now displays nodes even when they have no contexts.

  • Improved the layout of application details on the Overview page.

  • Reduced the time required to complete a migration after the preparation phase.

  • Reduced the number of threads used by event stores.

Bug Fixes

  • Fixed an issue with DCB persistent streams when using filters.

  • Fixed a replication issue that could occur when an application reported a persistent stream segment update after the stream had already been deleted.

  • Fixed a race condition in the DCB event store that could lead a SIGSEGV crash.

New Configuration Property

Property Description
axoniq.axonserver.accesscontrol.initial-admin-password Specifies the initial administrator password during startup.
