Since 2.35 was released on June 3rd, the four month release cycle takes us to the end of next month (September). I think it also makes sense to give an extra week or so due to StanCon Oxford taking place next month.
I am proposing the following dates:
As always, please use this thread if you have any thoughts on those dates, or if you need a pull request reviewed or think an issue is a high priority for this release.
sounds good to me. I’ve got some PRs about adding improved R-hat and ESS that need add’l work in order to get in for the next release - Feature/3299 improve ess mcse by mitzimorris · Pull Request #3305 · stan-dev/stan · GitHub et al
Bumping this for visibility post-StanCon
Tracking issue is up at Release CmdStan 2.36 · Issue #1296 · stan-dev/cmdstan · GitHub
For those keeping track, the feature freeze and subsequent release will almost certainly delayed while we pursue resolutions to Compilation failures under LLVM 19 · Issue #3106 · stan-dev/math · GitHub
This may involve a fair amount of work (possibly creating our own implementation of complex numbers stan::math and std::complex · Issue #3006 · stan-dev/math · GitHub) so it’s too early to give a new estimate for when the release would be
The above linked issue is resolved, but we want to take some time to look into a more complete solution to the issues that have been arising with std::complex support (3 out of the last 4 LLVM releases have broken stan-math because of these)
@stevebronder thinks this would be reasonable to do in a month’s time, so I’m proposing the following new timeline:
@stevebronder do you think we can get in the unit_vector repulsion thing for this release?
I think this would be next release.
I would very much appreciate this - I would love to see the rank-normalized rhat, ess for CmdStan go in and there’s a few things to nail down w/r/t Feature/3299 diagnostics chainset by mitzimorris · Pull Request #3310 · stan-dev/stan · GitHub and Feature/1263 update stansummary to report rank-normalized ESS tail, ESS bulk, max abs deviation(MAD), and Rhat by mitzimorris · Pull Request #1290 · stan-dev/cmdstan · GitHub
