Release 2022f - 2022-10-28 18:04:57 -0700

  Changes to future timestamps

    Mexico will no longer observe DST after 2022, except for areas
    near the US border that continue to observe US DST rules.
    On 2022-10-30 at 02:00 the Mexican state of Chihuahua moves
    from -07 (-06 with DST) to year-round -06, thus not changing
    its clocks that day.  The new law states that Chihuahua
    near the US border no longer observes US DST.
    (Thanks to gera for the heads-up about Chihuahua.)

    Fiji will not observe DST in 2022/3.  (Thanks to Shalvin Narayan.)
    For now, assume DST is suspended indefinitely.

  Changes to past timestamps

    Simplify four Ontario zones, as most of the post-1970 differences
    seem to have been imaginary.  (Problem reported by Chris Walton.)
    Move America/Nipigon, America/Rainy_River, and America/Thunder_Bay
    to 'backzone'; backward-compatibility links still work, albeit
    with some different timestamps before November 2005.
