There is an upcoming timezone change I want to inform you about. In Kazakhstan we are moving away from UTC+6 to UTC+5 across all areas of the country.
The change is effective at 00:00 1 march 2024.

Thanks; we were made aware of this change for Kazakhstan on 19 January. See:

For all Kazakhstan zones set local time back 1 hour night of February 29, 2024 to March 1, 2024 (at 00:00 hours)
Zone      Asia/Almaty
Zone      Asia/Qyzylorda
Zone      Asia/Qostanay
Zone      Asia/Aqtobe
Zone      Asia/Aqtau
Zone      Asia/Atyrau
Zone      Asia/Oral

Our understanding is that this change only affects the eastern portions of the country represented by Asia/Almaty and Asia/Qostanay, and not the other zones as those areas already observe UTC+5 so will not be changing their clocks. This appears to be reflected in the locations listed in the quoted legal text.

How I can know when this change will be released?

You may want to consider subscribing to the low-traffic tz-announce mailing list at

https://mm.icann.org/mailman/listinfo/tz-announce

which announces new tzdb releases as they come out.

There is no set schedule for a new release, as this is a volunteer project; however, we are obviously now aware that one is needed ahead of 1 March. So you can plan for a new release reasonably soon, once we've allowed folks some time to test and comment on the pending changes.

Have you some tracking or history of changes in database?

The main development copy of the database is kept on Github at

https://github.com/eggert/tz/commits/main

where you can find the upcoming change for Kazakhstan already in place:
