Comment 3 for bug 2058249

In Ubuntu 24.04 (noble) we have /usr/share/doc/tzdata/NEWS.Debian.gz:

tzdata (2023d-1) unstable; urgency=medium

    From 2023c-8 on the tzdata package ships only timezones that follow the
    current rules of geographical region (continent or ocean) and city name.
    All legacy timezone symlinks (old or merged timezones mentioned in the
    upstream backward file) were moved to tzdata-legacy. This includes the
    US/* timezones.

    Please install tzdata-legacy in case you need the legacy timezones or to
    restore the previous behavior. This might be needed in case the system
    provides timezone-aware data over the network (e. g. SQL databases).

The debian changelog contains for 2023c-8:

  * Ship only timezones in tzdata that follow the current rules of geographical
    region (continent or ocean) and city name. Move all legacy timezone symlinks
    (that are upgraded during package update) to tzdata-legacy. This includes
    dropping the special handling for US/* timezones. (Closes: #1040997)

Improvements to the documentation are welcome.
