Version 1.2.2 - 8-Aug-2014
--------------------------
* Fix an error with duplicates being returned by Timezone#all_country_zones
and Timezone#all_country_zone_identifiers when used with tzinfo-data
v1.2014.6 or later.
* Use the zone1970.tab file for country timezone data if it is found in the
zoneinfo directory (and fallback to zone.tab if not). zone1970.tab was added
in tzdata 2014f. zone.tab is now deprecated.
Version 1.2.1 - 1-Jun-2014
--------------------------
* Support zoneinfo files generated with zic version 2014c and later.
* On platforms that only support positive 32-bit timestamps, ensure that
conversions are accurate from the epoch instead of just from the first
transition after the epoch.
* Minor documentation improvements.
Version 1.2.0 - 26-May-2014
---------------------------
* Raise the minimum supported Ruby version to 1.8.7.
* Support loading system zoneinfo data on FreeBSD, OpenBSD and Solaris.
Resolves#15.
* Add canonical_identifier and canonical_zone methods to Timezone. Resolves#16.
* Add a link to a DataSourceNotFound help page in the TZInfo::DataSourceNotFound
exception message.
* Load iso3166.tab and zone.tab files as UTF-8.
* Fix Timezone#local_to_utc returning local Time instances on systems using UTC
as the local time zone. Resolves#13.
* Fix == methods raising an exception when passed an instance of a different
class by making <=> return nil if passed a non-comparable argument.
* Eliminate "require 'rational'" warnings. Resolves#10.
* Eliminate "assigned but unused variable - info" warnings. Resolves#11.
* Switch to minitest v5 for unit tests. Resolves#18.
Version 1.1.0 - 25-Sep-2013
---------------------------
* TZInfo is now thread safe. ThreadSafe::Cache is now used instead of Hash
to cache Timezone and Country instances returned by Timezone.get and
Country.get. The tzinfo gem now depends on thread_safe ~> 0.1.
* Added a transitions_up_to method to Timezone that returns a list of the times
where the UTC offset of the timezone changes.
* Added an offsets_up_to method to Timezone that returns the set of offsets
that have been observed in a defined timezone.
* Fixed a "can't modify frozen String" error when loading a Timezone from a
zoneinfo file using an identifier String that is both tainted and frozen.
Resolves#3.
* Support TZif3 format zoneinfo files (now produced by zic from tzcode version
2013e onwards).
* Support using YARD to generate documentation (added a .yardopts file).
* Ignore the +VERSION file included in the zoneinfo directory on Mac OS X.
* Added a note to the documentation concerning 32-bit zoneinfo files (as
included with Mac OS X).
Version 1.0.1 - 22-Jun-2013
---------------------------
* Fix a test case failure when tests are run from a directory that contains a
dot in the path (issue #29751).
Version 1.0.0 - 2-Jun-2013
--------------------------
* Allow TZInfo to be used with different data sources instead of just the
built-in Ruby module data files.
* Include a data source that allows TZInfo to load data from the binary
zoneinfo files produced by zic and included with many Linux and Unix-like
distributions.
* Remove the definition and index Ruby modules from TZInfo and move them into
a separate TZInfo::Data library (available as the tzinfo-data gem).
* Default to using the TZInfo::Data library as the data source if it is
installed, otherwise use zoneinfo files instead.
* Preserve the nanoseconds of local timezone Time objects when performing
conversions (issue #29705).
* Don't add the tzinfo lib directory to the search path when requiring 'tzinfo'.
The tzinfo lib directory must now be in the search path before 'tzinfo' is
required.
* Add utc_start_time, utc_end_time, local_start_time and local_end_time instance
methods to TimezonePeriod. These return an identical value as the existing
utc_start, utc_end, local_start and local_end methods, but return Time
instances instead of DateTime.
* Make the start_transition, end_transition and offset properties of
TimezonePeriod protected. To access properties of the period, callers should
use other TimezonePeriod instance methods instead (issue #7655).
