Axon Framework - Release 5.0.0

Announcements
1

Axon Framework 5 is finally here!!

The list of features, enhancements, bugs, and documentation is so large, that it does not fit in a typical forum post. As such, if you are curious about the full release notes, please take a look here.

For those looking to start with Axon Framework 5, we recommend you go through the Getting Started section of Axoniq Docs.
If you have an Axon Framework 4 background, for example, because you are looking to migrate an Axon Framework 4 application to Axon Framework 5, note that thorough migration tooling will follow in release 5.1.0 (please follow this issue when curious).
If you want to give a manual migration a go, we strongly recommend that you check out the /axon-5/api-changes.md file present in the Axon Framework project.
Although the api-changes.md is not strictly the migration guide, we will use it as the basis to form our future migration guide and documentation.

Hey @Steven_van_Beelen,
congrats on getting Axon Framework 5 out the door! :tada:

In order to plan the shift to the new major version it would be very helpful to have some information about the support plan for Axon Framework 4. How long do you provide bug and security fixes?

At least until all the major features in AF4 have been ported to AF5, one way or another.

For some features that’ll mean something is copied over and adjusted to the new API (EventSchedulers, for example), sometimes that means a rigorous rewrite for it to be more flexible in the future (snapshotting, for example).

As it stands, I assume we’ll have sufficient work until 5.3.0 to migrate everything to Axon Framework 5. Time-wise, that’ll be somewhere at the end of next year, if everything goes according to plan.
