<li>An unset TZ is no longer invalid when /etc/localtime is

<li>tzset etc. are now more cautious about questionable TZ settings.</li>
<li>tzset etc. now treat ' ' like '_' in time zone abbreviations</li>
<li>tzfree now preserves errno, consistently with POSIX.1-2024 "free".</li>
<li>zic has new options inspired by FreeBSD. </li>
<li>multiple changes visible to developers</li>
</ul>
</li>
<li>Use "REDO=posix_right" to keep installing "right" TZif files.</li>

<li>The main data form now uses %z.</li>

<li>Palestine springs forward a week later than previously predicted in 2024 and 2025.</li>
<li>Asia/Ho_Chi_Minh's 1955-07-01 transition occurred at 01:00 not 00:00.</li>

<li>In 1911 Miquelon adopted standard time on June 15, not May 15.</li>
<li>The FROM and TO columns of Rule lines can no longer be "minimum"
or an abbreviation of "minimum", because TZif files do not support
DST rules that extend into the indefinite past - although these
rules were supported when TZif files had only 32-bit data, this
stopped working when 64-bit TZif files were introduced in 1995.</li>

about 400 years after a switch to a time zone with a DST schedule.</li>

which conversion specs, and that tzset is called.</li>

<li>Casey, Antarctica changed time zones five times since 2020.</li>
<li>Code and data fixes for Palestine timestamps starting in 2072.</li>
<li>A new data file zonenow.tab for timestamps starting now.</li>
<li>Fix predictions for DST transitions in Palestine in
2072-2075, correcting a typo introduced in 2023a.</li>
<li>Vostok, Antarctica changed to +05 on 2023-12-18.
It had been at +07 (not +06) for years.</li>
<li>Change data for Casey, Antarctica to agree with
timeanddate.com, by adding five time zone changes since 2020.</li>

its standard time from -03 to -02 on 2023-03-25, not on 2023-10-28.</li>
<li>localtime.c no longer mishandles TZif files that contain
a single transition into a DST regime.</li>

<li>tzselect no longer mishandles the following:</li>
