I’m glad to announce that we’ve released Axon Framework version 4.13.0 on Feb 04, 2026.

Migration Support

Axon Framework 4.13. marks the migration support minor release!
As such, it is aimed at providing users a stepping stone from Axon Framework 4 to Axon Framework 5.

In this first migration support release, we focused on our largest integration with other tooling, which is Spring Boot.
Hence, as of 4.13., Axon Framework 4 support support Spring Boot 4+.
Furthermore, we increased the JDK version of Axon Framework 4 from JDK8 to JDK17.
This simplified our integration with Spring Boot 4, as well as aligns more closely with the paramount JDK increase to 21 for Axon Framework 5.

This release contains:
