- updated to version 1.0.0
* 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).
