Planning for 2.23 release

A nasty issue popped up: https://github.com/stan-dev/stanc3/issues/523

I dunno the threshold for hotfix bugs but since this is a silent one I’d like to get it fixed if possible (it came from Speeding up and reducing divergences for multivariate hiearchical stochastic factor model).

I’m all in favor of avoiding hotfixes - release Monday 4/27?

Let’s see if someone can identify where exactly the bug is first. Not sure about the difficulty of the fix.

fine, it’s OK to release with known bugs
(after all, we release with unknown bugs…)

Given that the bug turned out to not be as severe, we can proceed with the release. The only left question on the release is https://github.com/stan-dev/cmdstan/pull/862

Once that is merged (or decided to wait after the release) we can proceed.

I think we can let go 2.23 as is, see Makefiles and compiler flag `-DSTAN_THREADS` - always on?

My opinion. Others?

Hey @rok_cesnovar I’m on it!
Do we have release notes for math, stan and cmd-stan or should I take care of it ?
Edit: Found them!

@mitzimorris, @wds15 and I made a couple updates to the cmdstan tutorial: https://github.com/bbbales2/cmdstan_map_rect_tutorial . Can you upload the latest versions there to the case studies thing?

@bbbales2 - will do - done!

hi @serban-nicusor, the 2_23 docs were generated but not merged -

getting a 404 on this: https://mc-stan.org/docs/2_23/stan-users-guide/index.html
also expecting https://mc-stan.org/docs/2_22/stan-users-guide/index.html to have the message about “outdated” with link to latest.

this should be in place before we announce the release because part of the announcement is about the whole new section of the User’s Guide

Damn. It’s tagged! Cheers.

Hey, I think everything is done for the current release:

If anyone has a few minutes it would help a lot to double-check, thank you!
