  • passes black pandas
  • passes git diff upstream/master -u -- "*.py" | flake8 --diff
  • whatsnew entry

This executes some deprecations from the 0.23/0.24 cycles, namely following the switch from join=None to join='left' (following #18657 / #20347), as well as the fact that list-likes within list-likes were deprecated (following #21950 / #22264).

Since this deprecation closes the loop to my first-ever pandas issue (#18657) and PR (#20347), I'll allow myself a bit of a digression here. After biting off a bit more than I could chew (after finding out just how many cases the method was supposed to support), things got a bit tight with the cut-off for 0.23.0rc, and @TomAugspurger quipped:

@h-vetinari: Thanks for waiting with the cut-off! [...]

@TomAugspurger: Right, we'll keep you on the hook for future maintenance of this :)

After #20347 #20790 #20842 #20845 #20923 #21330 #21950 #22264 #22575 #22652 #22721 (-->#23011 #23163 #23167 #23582 ... and several more issues/PRs around .str-accessor) #22722 #22725 #23009 (-->#23061 #23065) #23187 #23443 #23723 #23725 #24044 #24045 #26605 #26607 etc., I think I can say that I upheld my end of the bargain. :)

how is this an api change? isn't it just a deprecation removal?

I thought that changing the default of a kwarg qualifies more as an API change than a removal, but I don't mind either way. Let me know if you want me to shift it.

We have a "Removal of prior version deprecations/changes" section, which IIUC is appropriate here.

what other issues besides #22644 does this remove? (you can look on #6581 for what we have deprecated)

@jreback: what other issues besides #22644 does this remove? (you can look on #6581 for what we have deprecated)

I think you might have mistyped with #22644? At least I don't see a relation.

As mentioned in the OP:

@h-vetinari: This executes some deprecations from the 0.23/0.24 cycles, namely following the switch from join=None to join='left' (following #18657 / #20347), as well as the fact that list-likes within list-likes were deprecated (following #21950 / #22264).
