Does someone know if the Unicode CLDR ../supplemental/windowsZones.xml has been updated?

Following the best links I know to find: Unicode CLDR Overview https://cldr.unicode.org/index/downloads/cldr-45 Downloads https://cldr.unicode.org/index/downloads GitHub Tag https://raw.githubusercontent.com/RobThree/TimeZoneMapper/master/TimeZoneMap...

This file says it corresponds with TzDb 2021a.

I agree this is confusing, but it appears to refer to the tzdb version resulting in changes to the XML schema effective version "typeVersion". Not sure of that. I've got other, earlier, that show <mapTimezones otherVersion="7e11500" typeVersion="2020a">On that line.

...

Yet other notes say Windows zone were updated to TzDb 2024a:

CLDR 45 Release Note https://cldr.unicode.org/index/downloads/cldr-45 Timezones Deprecating timezones that are no longer in zone.tab (America/Nipigon, ...) New Windows timezone mappings

Was this file not actually updated or am I looking in the wrong place?

The latest release-45 log message for both:

https://github.com/unicode-org/cldr/blob/release-45/common/supplemental/meta...

https://github.com/unicode-org/cldr/blob/release-45/common/supplemental/wind...

says they were updated by:

    CLDR-17351 Updating CLDR time zone data with IANA TZDB 2024a     https://unicode-org.atlassian.net/browse/CLDR-17351 Yes. But that file https://github.com/unicode-org/cldr/blob/release-45/common/supplemental/wind... 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/9d96f340ab145003b3e6d12d95ffb16f1... 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, -Brooks

and log message -2 for release-45:

https://github.com/unicode-org/cldr/blob/release-45/common/supplemental/supp...

re zoneAlias entries says it was updated by:

CLDR-17295 tz2023d data updates and cleaned up deprecated zones/metazone #3442     https://unicode-org.atlassian.net/browse/CLDR-17295

as part of:

    ICU-22620 tz2023d updates unicode-org/icu#2777     https://unicode-org.atlassian.net/browse/ICU-22620

indicating that recently they seem to evaluate the impact of tzdb releases within a week or two;
