News for the tz database
+Release 2015d - 2015-04-24 08:09:46 -0700
+
+ Changes affecting future time stamps
+
+ Egypt will not observe DST in 2015 and will consider canceling it
+ permanently. For now, assume no DST indefinitely.
+ (Thanks to Ahmed Nazmy and Tim Parenti.)
+
+ Changes affecting past time stamps
+
+ America/Whitehorse switched from UTC-9 to UTC-8 on 1967-05-28, not
+ 1966-07-01. Also, Yukon's time zone history is documented better.
+ (Thanks to Brian Inglis and Dennis Ferguson.)
+
+ Change affecting past and future time zone abbreviations
+
+ The abbreviations for Hawaii-Aleutian standard and daylight times
+ have been changed from HAST/HADT to HST/HDT, as per US Government
+ Printing Office style. This affects only America/Adak since 1983,
+ as America/Honolulu was already using the new style.
+
+ Changes affecting code
+
+ zic has some minor performance improvements.
+
+
+Release 2015c - 2015-04-11 08:55:55 -0700
+
+ Changes affecting future time stamps
+
+ Egypt's spring-forward transition is at 24:00 on April's last Thursday,
+ not 00:00 on April's last Friday. 2015's transition will therefore be on
+ Thursday, April 30 at 24:00, not Friday, April 24 at 00:00. Similar fixes
+ apply to 2026, 2037, 2043, etc. (Thanks to Steffen Thorsen.)
+
+ Changes affecting past time stamps
+
+ The following changes affect some pre-1991 Chile-related time stamps
+ in America/Santiago, Antarctica/Palmer, and Pacific/Easter.
+
+ The 1910 transition was January 10, not January 1.
+
+ The 1918 transition was September 10, not September 1.
+
+ The UTC-4 time observed from 1932 to 1942 is now considered to be
+ standard time, not year-round DST.
+
+ Santiago observed DST (UTC-3) from 1946-07-15 through 1946-08-31,
+ then reverted to standard time, then switched its time zone to
+ UTC-5 on 1947-04-01.
+
+ Assume transitions before 1968 were at 00:00, since we have no data
+ saying otherwise.
+
+ The spring 1988 transition was 1988-10-09, not 1988-10-02.
+ The fall 1990 transition was 1990-03-11, not 1990-03-18.
+
+ Assume no UTC offset change for Pacific/Easter on 1890-01-01,
+ and omit all transitions on Pacific/Easter from 1942 through 1946
+ since we have no data suggesting that they existed.
+
+ One more zone has been turned into a link, as it differed
+ from an existing zone only for older time stamps. As usual,
+ this change affects UTC offsets in pre-1970 time stamps only.
+ The zone's old contents have been moved to the 'backzone' file.
+ The affected zone is America/Montreal.
+
+ Changes affecting commentary
+
+ Mention the TZUpdater tool.
+
+ Mention "The Time Now". (Thanks to Brandon Ramsey.)
+
+
