RLS: 1.0.4

[simonjayhawkins]

we have several regressions reported since 1.0.3 (not due to 1.0.3, since 0.25.3) and a couple that had not been fixed.

https://github.com/pandas-dev/pandas/issues?page=1&q=is%3Aopen+is%3Aissue+label%3ARegression

Is there any that warrant a 1.0.4 release?

I probably won't be able to help with one this week, but the scripts at https://github.com/pandas-dev/pandas-release should be reasonably up to date.

We'll need to manually verify that all the necessary PRs have been backported (I don't think they have). It might be easier to do a 1.1 release soon.

I don't think this is urgent. It's more a matter of whether we should be labelling PRs that fix regressions as 1.0.4 and backporting.

It might be easier to do a 1.1 release soon.

IMO we should be ensuring that the 1.0.x fixes regressions from 0.25.3. 1.1 could introduce new regressions. so this is about ensuring an upgrade path for affected users.

@simonjayhawkins I think in the call last week we decided to leave it up to you. If you have time to go through and backport the necessary PRs for a release we can go ahead and do it.

In addition to backporting, I think that

• BLD: add msvcp DLL to windows wheel build MacPython/pandas-wheels#82
• MacPython/pandas-wheels wheel builds failing #33210

are blockers.

[simonjayhawkins]

potential backports (add to this list)

• BUG: None converted to NaN after groupby first and last #33462 (regression in 1.0.2)

@simonjayhawkins still working on this?

[simonjayhawkins]

When this issue was opened there was no PRs merged to master that fixed regressions. There were also blockers to doing a release, #33300 (comment).

I've not been working on this, but now we are a few weeks on and the blockers are resolved, we now have a few PRs that could be backported.

I could start backporting these if we are likely to do a 1.0.4 release.

[TomAugspurger]

At this point, I think pushing for a 1.1 release in a week or two is probably easier.

[jreback]

I actually would be +1 on a 1.0.4; I also think this is orthogonal to doing 1.1, and good for others to try a release.

In addition to backporting, I think that

• MacPython/pandas-wheels#82
• MacPython/pandas-wheels wheel builds failing #33210

are blockers.

#32737 wasn't backported, so #33210 shouldn't be an issue here?
