1.0.0

After more than 300 commits and 21 beta releases, pendulum finally reaches its first stable version.

What does that mean? Well, the API is now stable, so no backwards compatibility breaking changes will be introduced in any 1.x releases (pendulum will follow Semantic Versioning).

Changed

• Using PRE_TRANSITION rule no longer produces a time in a DST gap.
• Improved performances when adding time to a Pendulum instance.
• Improved parsing of ISO 8601 strings.
• Removed deprecated methods

0.8.0

Added

• Added on() and at() methods which replace with_date() and with_time().
• Added a strict keyword argument to parse() to get the type matching the parsed string.
• Added the ability to pass an amount to the range() method to control the length of the gap.
• Added a datetime() helper method to the Timezone class.

Changed

• Improved parsing of ISO 8601 strings.

Deprecated

• with_date() and with_time() are deprecated. Use on() and at() instead.
• create_from_date() and create_from_time() are deprecated. Use create() instead.

0.7.0

Added

• Added a Date class.
• Added a Time class.
• Added experimental support for the fold attribute introduced in Python 3.6.
• Added a remaining_days property to the Interval class.
• Added a int_timestamp property to the Pendulum class to retrieve the behavior of the now deprecated timestamp property.
• start_of()/end_of() now supports hour, minute and second units.
• astimezone() now supports timezone strings.
• in_words() now displays subseconds when no other units are available.

Changed

• Period properties (especially years and months) are now accurate.
• Interval.seconds now returns the whole number of remaining seconds, like timedelta, for compatibility. Use remaining_seconds to retrieve the previous behavior.
• Improved parsing performances for common formats.
• The library no longer relies on pytz. It now depends on pytzdata for its timezone database.
• Locale, test instance and formatter are now set gobally at the module level when using the corresponding module methods.

Deprecated

• timestamp should now be used as a method and no longer as a property. It will be a native method in the next major version.
• Interval properties and methods related to years and months are now deprecated.
• Interval.days_exclude_weeks is now deprecated. Use remaining_days instead.

Fixed

• Exception when loading specific timezones has been fixed.
• end_of('day') now properly sets microseconds to 999999.
• Accuracy of Period instances properties has been improved.
• Accuracy for microseconds when initializing a Pendulum instance in some timezones has been fixed.
• Periods are now serializable with pickle.
• Fixed minute_(), second_() and microsecond_() setters changing the hour unit.
• Fixed Windows support.

0.6.6

Fixed

• Fixed a memory leak in C extension. (thanks to ntoll)

0.6.5

Changed

• Adds validation to set_week_starts_at(), set_week_ends_at() and set_weekend_days(). (thanks to kleschenko)
• Updates ukrainian localization. (thanks to kleschenko)

Fixed

• Fixes loading of timezones without transitions.
• Fixes Timezone.utcoffset(). (thanks to regnarock)

0.6.4

Changed

• Adds support for pytz timezones in constructor.

Fixed

• Fixes behavior of add()/subtract() methods for years, months and days when a DST transition occurs.
• Fixes range() behavior.

0.6.3

Changed

• Fixes pickling/unpickling of Pendulum instances with fixed timezone.

0.6.2

Fixed

• Fixes timezones loading on Windows

0.6.1

Changed

Fixed

• Fixes Timezone._convert() method for fixed timezones.

• Fixes comparisons to incompatible objects raising an error.

0.6.0

Added

• Adds an option to control transition normalization behavior.
• Adds a separator keyword argument to Interval.in_words() method.
• Adds an alternative formatter.
• Adds support for pretty much any tzinfo instance in the instance() method.
• Adds an intersect() method to the Period class.

Changed

• Improves meridians formatting by supporting minutes.
• Changes behavior of create*() methods (time now defaults to 00:00:00)

Fixed

• Fixes setters and modifiers (start_of/end_of) to properly apply transitions.
• Fixes issue when compiling on 32 bit systems. (Thanks to guyzmo)
• Fixes NameError Exception on Python 3.2. (Thanks to guyzmo)
