Version 0.2.1 of TZInfo has been released (based on version 2006d of the
underlying tz data).

Gem, zip and tar.gz files can be found at
http://rubyforge.org/frs/?group_id=894. You can use 'gem update' to
upgrade if you already have the tzinfo gem installed.


Changes in this release:

* Fix a performance issue caused in 0.2.0 with Timezone.local_to_utc. 
Conversions performed on TimeOrDateTime instances passed to <=> are now 
cached as originally intended. Thanks to Michael Smedberg for spotting this.

* Fix a performance issue with the local_to_utc period search algorithm 
originally implemented in 0.1.0. The condition that was supposed to 
cause the search to terminate when enough periods had been found was 
only being evaluated in a small subset of cases. Thanks to Michael 
Smedberg and Jamis Buck for reporting this.

* Added abbreviation as an alias for TimezonePeriod.zone_identifier.

* Updated to tzdata version 2006d 
(http://article.gmane.org/gmane.comp.time.tz/936).

* Ignore any offset in DateTimes passed in (as is already done for 
Times). All of the following now refer to the same UTC time (15:40 on 17 
April 2006). Previously, the DateTime in the second line would have been 
interpreted as 20:40.

   tz.utc_to_local(DateTime.new(2006, 4, 17, 15, 40, 0))
   tz.utc_to_local(
     DateTime.new(2006, 4, 17, 15, 40, 0).new_offset(Rational(5, 24)))
   tz.utc_to_local(Time.utc(2006, 4, 17, 15, 40, 0))
   tz.utc_to_local(Time.local(2006, 4, 17, 15, 40, 0))
