Release Notes
Changes affecting near-future timestamps
Tocantins will very likely not observe DST starting this spring.
(Thanks to Steffen Thorsen.)
Jordan will likely stay at UT +03 indefinitely, and will not fall
back this fall.
Palestine will fall back at 00:00, not 01:00. (Thanks to Steffen Thorsen.)
Changes affecting API
The types of the global variables 'timezone' and 'altzone' (if present)
have been changed back to 'long'. This is required for 'timezone'
by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
These variables were originally 'long' in the tz code, but were
mistakenly changed to 'time_t' in 1987; nobody reported the
incompatibility until now. The difference matters on x32, where
'long' is 32 bits and 'time_t' is 64. (Thanks to Elliott Hughes.)
Changes affecting the build procedure
Avoid long strings in leapseconds.awk to work around a mawk bug.
(Thanks to Cyril Baurand.)
Changes affecting documentation and commentary
New file 'NEWS' that contains release notes like this one.
Paraguay's law does not specify DST transition time; 00:00 is customary.
(Thanks to Waldemar Villamayor-Venialbo.)
Minor capitalization fixes.
Changes affecting version-control only
The experimental GitHub repository now contains annotated and
signed tags for recent releases, e.g., '2013e' for Release 2013e.
Releases are tagged starting with 2012e; earlier releases were
done differently, and tags would either not have a simple name or
not exactly match what was released.
'make set-timestamps' is now simpler and a bit more portable.
