From Paul Eggert's comments:

Changes that affect near-future time stamps:

  * Western Australia starts DST on December 3.  (Thanks to
    Jesper Norgaard Welen for the initial warning, and to Christopher Hunt
    for letting us know it was official.)

    This patch migrates the WA DST idiosyncracies into Rule lines,
    where they probably belonged anyway.  I realize the official
    legislation specifies dates rather than "Mar lastSun", but we
    commonly reverse-engineer the underlying rules in other situations
    and might as well do so consistently here.

Changes affecting location data only:

  * The coordinates for Jersey and Podgorica were off.
    (Thanks to Andy McDonald for noting this.)
