europe Pridnestrovian Moldavian Republic (Europe/Tiraspol)
has followed much of Russia, and will retain "summer time"
year round (that is no time transition is due Oct 30).
This reintroduces a zone that had earlier been removed,
and so removes the "backward" link.
On the other hand, Ukraine have decided not to follow,
so the change which had been made in preparation for
that in tzdata2011k is now reverted, and there will be
a transition on Oct 30.
The change to Bahia, Brazil, that introduced summer time
(following the regular Brazil rules, so commencing this
year on Oct 16 - last SUnday) that was mooted before tzdata2011l
was released, but withdrawn becase the change was not yet
official, has now been ratified.
Aside from that, the other files that were changed in tzdata2011l
but where the sccs id was not altered, have all been given new version
numbers (southamerica has gone up by two, one for the 2011l changes, and
another for this set).
