Major Releases

Release 4.6.0

Standard Edition and Enterprise Edition
New features:
  • Streaming queries (requires Axon Framework version 4.6.0). When returning a collection of results from a query, the results can be streamed instead of collecting them in the query handler first.
  • Number of events per transaction is no longer limited to 32K.
  • Support for using the CLI when the caller is behind a proxy.
  • livenessstate and readinessstate probes are now included in the /actuator/health endpoint output by default
  • Properties now support more readable values using units
  • Changing event processor states through Axon Server now waits for a result from the client
  • Plugins can now use AxonServerInformationProvider to get information on the Axon Server version
  • UI updated
  • show complex metadata values in query results
Dependency updates:
  • updated gRPC and Netty versions
  • updated Spring Boot version
  • moved to OpenAPI for Swagger support
Bug fixes:
  • moved reading indexes from the gRPC thread to prevent blocking these threads
  • For the Swagger endpoint use /swagger-ui.html or /swagger-ui/index.html.
  • The generic endpoint for actuator is /actuator (/actuator/ no longer works)
Enterprise Edition only
New features:
  • Clients can now perform administrative operations in Axon Server through the axonserver-connector-java (requires version 4.6.0 of the connector).
  • Support for updating properties for an existing context
  • Large message support. Before increasing the max-message-size on Axon Server had the effect that the replication log segments were also increased in size. This dependency is no longer there.
  • Clients can now also connect to nodes in a replication group that are not primary or messaging-only nodes. To force clients to connect to primary or message-only nodes, set the property force-connection-to-primary-or-messaging-node to true
Bug fixes:
  • not able to use an empty internal domain value if the domain was specified for the client connections (requires property axoniq.axonserver.experimental.allow-empty-domain set to true and axoniq.axonserver.internal-domain defined with an empty string)
  • fix a timing issue in LeadershipStatusNotifier that can cause the leader to forget about its own leader status
  • For the swagger endpoint use /swagger-ui.html or /swagger-ui/index.html.
  • The generic endpoint for actuator is /actuator (/actuator/ no longer works)
  • If you are using the LDAP or OATH extension you need to use the 4.6.0 version of these extensions as because of the Spring Boot version update

Release 4.5

Standard Edition and Enterprise Edition
New features:
  • Support for customer-defined plugins to add custom actions to adding/reading events and snapshots and executing commands and (subscription queries) For more information see plugins.

  • Updates in user permissions now have immediate effect (even if the user is logged in)
  • Logging of illegal access to Axon Server gRPC services
  • Improved monitoring of available disk space (see actuator-endpoints)
  • List of used 3rd party libraries available from Dashboard
  • Axon Dashboard checks for Axon Server version updates
Dependency updates:
  • updated gRPC and Netty versions
  • updated Spring Boot version
  • updated Swagger version
  • Due to the update of the Spring Boot version there are some minor changes to the output of the /actuator/health endpoint. This endpoint now uses the element "components" instead of "details" to output the health per subcategory.
  • The swagger endpoint has changed from /swagger-ui.html to /swagger-ui/.
Standard Edition only
Bug fixes:
  • Read aggregate snapshots from closed segments fixed
Enterprise Edition only
New features:
  • Authentication via Google OAuth (via extension)
  • Authentication and authorization with LDAP

  • License status added to health page (see actuator-endpoints)
  • Migration tool now supports migrating from a MongoDB event store to Axon Server
Bug fixes:
  • memory leak in the replication group leader could cause elections
  • incorrect version number shown in login page and error page in Dashboard
  • invalid number of active subscription queries displayed in Dashboard
  • exception initializing a context for the replication group leader on restart after unclean shutdown

  • Default setting for health endpoint (/actuator/heath) has changed to show more details.
  • Change in TLS configuration for communication between AxonServer nodes (new property axoniq.axonserver.ssl.internal-trust-manager-file)
