Strong yes from me also. The question is only 4/10 (Friday) or 4/13 (monday)
On Math its probably all the neg binomial stuff. I didnt follow that PRs closely, @martinmodrak would know more.
I dont think there are any pressing issue on Stan/Cmdstan.
For stanc3 I think these three are the most pressing and hopefully simple:
I have an updated release notes (14 days behind to be exact) for Math ready (for the Release notes PR comments stuff we were discussing but I havent gotten around to yet). Stan/Cmdstan/stanc3 release notes should be easy and short and ready together with the RC release.
The neg. binomial stuff is currently on the back burner due to Covid-related activity which currently feels of higher priority. Quite likely will return to normal in a few days so reasonably likely that I’ll be able to move the neg. binomial stuff over the finish line in time. Everybody stay safe.
neg_binomial_2_log_lpmf has some outstanding numerical issues, the worst parts were fixed in https://github.com/stan-dev/math/pull/1622 but not all, but I think the issues now occur only for quite large phi. My aim with that was to very closely follow the current neg_binomial_2_lpmf (non-log) implementation and tests, only with the log substituted…
