@LorenzoBettini thought we want to bring in your pr first?
or will this be no problem?

[LorenzoBettini]

@cdietrich I had already rebased my PR on top of the released main, and solved the conflicts due to the new MWE2.

I guess you're right: bringing my PR in first should save for further conflicts.

So let's postpone this; probably, it will be even easier to simply recreate this PR, since I used the fix version script after all.

@cdietrich so shall we merge the Java 17 PR?

[cdietrich]

@LorenzoBettini are the open points addressed?

[LorenzoBettini]

@cdietrich I thought we'd address open points in the future. I seem to recall that there are no blocking open points. CC @szarnekow

[cdietrich]

future = as in a follow up or as "somewhen in 2027"

[LorenzoBettini]

That depends on us. It also depends on the importance of the open points.

[cdietrich]

from my pov they should be adressed before the next release

[LorenzoBettini]

OK, can you please point me to the points that remain to be addressed? I'll see what I can do.
Or summarize them in the other PR.
