- Mongolia will start observing DST again this year, from the last Saturday in March at 02:00 to the last Saturday in September at 00:00.
- Palestine will start DST on March 28, not March 27. Also, correct the fall 2014 transition from September 26 to October 24. Adjust future predictions accordingly.
- The 1982 zone shift in Pacific/Easter has been corrected, fixing a 2015a regression.
- Some more zones have been turned into links, when they differed from existing zones only for older time stamps. As usual, these changes affect UTC offsets in pre-1970 time stamps only. Their old contents have been moved to the 'backzone' file. The affected zones are: America/Antigua, America/Cayman, Pacific/Midway, and Pacific/Saipan.
- Correct the 1992-2010 DST abbreviation in Volgograd from "MSK" to "MSD".
