Sourced fromtzinfo's releases.

v2.0.5

• ChangedDateTime results to always use the proleptic Gregorian calendar. This affectsDateTime results prior to 1582-10-15 and any arithmetic performed on the results that would produce a secondary result prior to 1582-10-15.
• Added support for eager loading all the time zone and country data by calling eitherTZInfo::DataSource#eager_load! orTZInfo.eager_load!. Compatible with Ruby On Rails'eager_load_namespaces.#129.
• Ignore the SECURITY file from Arch Linux's tzdata package.#134.

TZInfo v2.0.5 on RubyGems.org

v2.0.4

• Fixed an incorrectInvalidTimezoneIdentifier exception raised when loading a zoneinfo file that includes rules specifying an additional transition to the final defined offset (for example, Africa/Casablanca in version 2018e of the Time Zone Database).#123.

TZInfo v2.0.4 on RubyGems.org

v2.0.3

• Added support for handling "slim" format zoneinfo files that are produced by default by zic version 2020b and later. The POSIX-style TZ string is now used calculate DST transition times after the final defined transition in the file.#120.
• FixedTimeWithOffset#getlocal returning aTimeWithOffset with thetimezone_offset still assigned when called with an offset argument on JRuby 9.3.
• Rubinius is no longer supported.

TZInfo v2.0.3 on RubyGems.org

v2.0.2

• Fixed 'wrong number of arguments' errors when running on JRuby 9.0.#114.
• Fixed warnings when running on Ruby 2.8.#113.

TZInfo v2.0.2 on RubyGems.org

v2.0.1

• Fixed "SecurityError: Insecure operation - require" exceptions when loading data with recent Ruby releases in safe mode.#100.
• Fixed warnings when running on Ruby 2.7.#109.
• Added aTZInfo::Timezone#=~ method that performs a regex match on the time zone identifier.#99.
• Added aTZInfo::Country#=~ method that performs a regex match on the country code.

TZInfo v2.0.1 on RubyGems.org

v2.0.0

Added

• to_local andperiod_for instance methods have been added toTZInfo::Timezone. These are similar toutc_to_local andperiod_for_utc, but take the UTC offset of the given time into account.
• abbreviation,dst?,base_utc_offset andobserved_utc_offset instance methods have been added toTZInfo::Timezone, returning the abbreviation, whether daylight savings time is in effect and the UTC offset of the time zone at a specified time.
• ATZInfo::Timestamp class has been added. It can be used withTZInfo::Timezone in place of aTime orDateTime.
• local_time,local_datetime andlocal_timestamp instance methods have been added toTZInfo::Timezone. These methods construct localTime,DateTime andTZInfo::Timestamp instances with the correct UTC offset and abbreviation for the time zone.
• Support for a (yet to be released) version 2 of tzinfo-data has been added, in addition to support for version 1. The new version will remove the (no longer needed)DateTime parameters from transition times, reduce memory consumption and improve the efficiency of loading timezone and country indexes.
• ATZInfo::VERSION constant has been added, indicating the TZInfo version number.

Changed

• The minimum supported Ruby versions are now Ruby MRI 1.9.3, JRuby 1.7 (in 1.9 or later mode) and Rubinius 3.
• Local times are now returned using the correct UTC offset (instead of using UTC).#49 and#52.
• Local times are returned as instances ofTimeWithOffset,DateTimeWithOffset orTZInfo::TimestampWithOffset. These classes subclassTime,DateTime andTZInfo::Timestamp respectively. They override the default behaviour of the base classes to return information about the observed offset at the indicated time. For example, the zone abbreviation is returned when using the%Z directive withstrftime.
• Thetransitions_up_to,offsets_up_to andstrftime instance methods ofTZInfo::Timezone now take the UTC offsets of given times into account (instead of ignoring them as was previously the case).
• TheTZInfo::TimezonePeriod class has been split into two subclasses:TZInfo::OffsetTimezonePeriod andTZInfo::TransitionsTimezonePeriod.TZInfo::OffsetTimezonePeriod is returned for time zones that only have a single offset.TZInfo::TransitionsTimezonePeriod is returned for periods that start or end with a transition.
