@jackiekazil Thanks! Could you review #2369 and then re-generate the release notes?

@tpike3 would you like this beta to wait for your update of the tutorial? (latest docs get updated between releases)

[jackiekazil]

@EwoutH - done. I can update the date and release it tomorrow if that works for you.

[EwoutH]

Awesome! #2381 should be included, and then we can release.

I think the significant part of the highlights should be about the examples now being in Mesa itself, being directly importable and being included in the docs.

I’m going to pre-approve this PR, so you can merge without any hassle when it’s ready.

If you get stuck in any part of the process, just say where you left it and I can finish it tomorrow morning. Otherwise I look forward to waking up to a new pre-release! :)

@EwoutH, this is complete. I think I got everything, but I would love a second review to make sure I didn't miss anything.
