| Avoid using the version `2.4.240` of H2. It has a bug causing performance degradations in certain subqueries, which are used by cascade delete. | ||

When would we delete this note? When the bug is fixed? Or are they not planning on doing so?

When a release with a bugfix is available.
I am a bot uneasy wether we can (legally) highlight this bug. Alternatively we could phrase a positive message and state that the max supported minor version is 2.3.x.

Is there a public bug report? Or did we just identify that during testing?
I agree to a positive formulation, but if that is a publicly known bug, I don't see an issue mentioning that.

| Even though there are newer versions available, we cannot recommend using them for now. Therefore we only support until version 2.3.x of H2. This recommendation is subject to change. If our test results allow to recommend newer versions we will do so. | |

Thanks @MattSchur ! What do we do with that now?
@agoerler @MattSchur A more positive formulation or stay as it is now and add a link to the bug report?
