Dropping 32-bit support, was this already discussed somewhere recently? (the linked issue seems to be mainly older comments)

I am just linking for posterity.

[jorisvandenbossche]

I am just linking for posterity.

I understand, but that means we decided to drop 32-bit support for 0.25.0 ?
And my question was: is there a discussion somewhere about this decision? (I don't think I am opposed, but still good to have this decision recorded somewhere)

[jreback]

that's the issue, this was long ago discussed. I see no reasont keep this burden (and actually the doc note is just to say we are going to do it).

[jbrockmendel]

There was some discussion of finding out usage stats for 32bit python on windows. Did anything come of that?

[TomAugspurger]

For conda downloads, Linux and Mac 32-bit downloads are negligible (Anaconda Distribution dropped Mac 32 and will drop 32-bit Linux this year). For windows, the split is 94% to 6% for 64-bit to 32-bit.

thanks @TomAugspurger yeah main motivation is that we don't have great testing, its just daily and hard to repro / fix.

[TomAugspurger]

We do test on 32-bit windows, right? So perhaps drop support for 32-bit linux?

[jreback]

no we only test on 64-bit windows

[jreback]

in fact we only here about 32-bit windows at release time I think (when wheels are built)

[jreback]

any objections?

[jorisvandenbossche]

@jreback can you raise this again in the original issue (#15889), and give people that participated there some time to respond?

(@TomAugspurger can you repeat those numbers there?)

[jorisvandenbossche]

@jreback I already applied the part of this commit about the py27 warning to master and merged master in your branch. So now this is only about 32bit.
