Not sure of that. I've got other, earlier, that show
<mapTimezones otherVersion="7e11500" typeVersion="2020a">On that line.

Yes. But that file
https://github.com/unicode-org/cldr/blob/release-45/common/supplemental/windowsZones.xml
is identical to the one I have downloaded back with 2021.

I've also downloaded cldr-common-45.0.zip. It contains this same file.

It does not reflect the commits Paul refereed to:
https://github.com/unicode-org/cldr/commit/9d96f340ab145003b3e6d12d95ffb16f19a8a529
or any others since 2021a, as far as I can tell.

So I'm confused (its not hard to confuse me).
What is the best procedure to obtain the latest windowsZones.xml?
Is there a record of earlier versions? I anticipate wanting to possibly 
reviewing earlier versions.

Thanks,
