Release Notes
Changes affecting near-future timestamps:
Jordan switches back to standard time at 00:00 on December 20, 2013.
The 2006-2011 transition schedule is planned to resume in 2014.
(Thanks to Steffen Thorsen.)
Changes affecting past timestamps:
In 2004, Cuba began DST on March 28, not April 4.
(Thanks to Steffen Thorsen.)
Changes affecting code
The compile-time flag NOSOLAR has been removed, as nowadays the
benefit of slightly shrinking runtime table size is outweighed by the
cost of disallowing potential future updates that exceed old limits.
Changes affecting documentation and commentary
The files solar87, solar88, and solar89 are no longer distributed.
They were a negative experiment - that is, a demonstration that
tz data can represent solar time only with some difficulty and error.
Their presence in the distribution caused confusion, as Riyadh
civil time was generally not solar time in those years.
tz-link.htm now mentions Noda Time. (Thanks to Matt Johnson.)
