The 2022d release of the tz code and data is available.

This release reflects the following changes:

   Briefly:
     Palestine transitions are now Saturdays at 02:00.
     Simplify three Ukraine zones into one.

   Changes to future timestamps

     Palestine now springs forward and falls back at 02:00 on the
     first Saturday on or after March 24 and October 24, respectively.
     This means 2022 falls back 10-29 at 02:00, not 10-28 at 01:00.
     (Thanks to Heba Hamad.)

   Changes to past timestamps

     Simplify three Ukraine zones to one, since the post-1970
     differences seem to have been imaginary. Move Europe/Uzhgorod and
     Europe/Zaporozhye to 'backzone'; backward-compatibility links
     still work, albeit with different timestamps before October 1991.

PS. If your tzdata parser does not yet support negative DST offsets or
times past 24:00, or if it insists on a 'pacificnew' file that is no
longer present, this release's data entries can be turned into a
rearguard-format tarball that should work even with these older parsers.
This is intended to be a temporary transition aid for these parsers. To
generate a rearguard-format tarball, obtain the full distribution as
described above, and run the command 'make DATAFORM=rearguard
tailored_tarballs' on a development host. Or you can run 'make
rearguard.zi' to generate a single file that can be fed directly to a
parser that works like 'zic'.
