# The POSIXRULES macro controls interpretation of nonstandard and obsolete

-# Nonempty POSIXRULES is obsolete and should not be relied on, because:
+# Any other value for POSIXRULES is obsolete and should not be relied on, as:
# * It does not work correctly in popular implementations such as GNU/Linux.
# * It does not work in the tzdb implementation for timestamps after 2037.
# * It is incompatible with 'zic -b slim' if POSIXRULES specifies transitions
# at standard time or UT rather than at local time.
# In short, software should avoid ruleless settings like TZ='EET-2EEST'
# and so should not depend on the value of POSIXRULES.

+Release 2020b - 2020-10-06 18:35:04 -0700
+
+ Briefly:
+ Revised predictions for Morocco's changes starting in 2023.
+ Canada's Yukon changes to -07 on 2020-11-01, not 2020-03-08.
+ Macquarie Island has stayed in sync with Tasmania since 2011.
+ Casey, Antarctica is at +08 in winter and +11 in summer.
+ zic no longer supports -y, nor the TYPE field of Rules.
+
+ Changes to future timestamps
+
+ Morocco's spring-forward after Ramadan is now predicted to occur
+ no sooner than two days after Ramadan, instead of one day.
+ (Thanks to Milamber.) The first altered prediction is for 2023,
+ now predicted to spring-forward on April 30 instead of April 23.
+
+ Changes to past and future timestamps
+
+ Casey Station, Antarctica has been using +08 in winter and +11 in
+ summer since 2018. The most recent transition from +08 to +11 was
+ 2020-10-04 00:01. Also, Macquarie Island has been staying in
+ sync with Tasmania since 2011. (Thanks to Steffen Thorsen.)
+
+ Changes to past and future time zone abbreviations and DST flags
+
+ Canada's Yukon, represented by America/Whitehorse and
+ America/Dawson, changes its time zone rules from -08/-07 to
+ permanent -07 on 2020-11-01, not on 2020-03-08 as 2020a had it.
+ This change affects only the time zone abbreviation (MST vs PDT)
+ and daylight saving flag for the period between the two dates.
+ (Thanks to Andrew G. Smith.)
+
+ Changes to past timestamps
+
+ Correct several transitions for Hungary for 1918/1983.
+ For example, the 1983-09-25 fall-back was at 01:00, not 03:00.
+ (Thanks to Géza Nyáry.) Also, the 1890 transition to standard
+ time was on 11-01, not 10-01 (thanks to Michael Deckers).
