Hi, what is the latest status on Java 21 support? Is it still considered experimental per the docs, or has it moved on since then? If it is, what's holding it back?

I am on java 21 + flink 2.2 no issue so far pretty solid experience. Probably the wording on the docs need to be more explicit, reading it again I’ve the impression java 21 is fully supported

Thanks, @Evan NotEvan - that's good to hear. I'm sure we're not the only organisation that would like to see an explicit statement of support, though.
