**BREAKING CHANGES** in the Registry API.
* Dropped the ``IsoRegistry.items()`` method,
* Started deprecation of the ``IsoRegistry.get_calendar_class`` method.
**New Calendar**
- Added Kenyan calendar, by @KidkArolis (#484)
**Minor fixes**
- Fixed Lithuania calendar to use the core flags for Assumption and All Saints (#468).
- Fixed Malta calendar ; January 1st was already included, no need to add it to the ``FIXED_HOLIDAYS`` property (#469).
- Small refactor in Netherlands calendar to use core constants (#470).
Change:
- Added BrazilBankCalendar to support `include_` flags and make it possible to extend and change these flags to support custom bank calendars (#474).
- Added Israel holidays eves and removed holidays which are not affecting the working days in Israel (#461).
- Fix warning in China's holidays to dynamically read supported years, thx @fredrike (#459).
Expanding @fredrike's idea, I've changed the way this warning message was generated.
Several reasons:
* Depending on your Python version, the message was sometimes a bit awkward, with years being in disorder (e.g.: "year 2019, 2020, 2018"). Dictionaries are strange.
* If we plan for the future, it wouldn't have been readable to have warnings with "2018, 2019, 2020, 2021, 2022, 2023, etc". An interval is more future-proof.
* Added tests, because tests are great ;o)
refs #459
refs #451
* Fix Robert E. Lee's Birthday label rules (renamed as of year 2016 into the neutral "State Holiday")
* (hopefully) Fixed Washington's Birthday observance around Christmas time
* Fix Confederate Memorial Day label rules (renamed as of year 2016 into the neutral "State Holiday")
closes #454
It fixes two things:
* Family Day was introduced in 2013, workalendar was assuming it was there before
* In 2019, Family Day was moved from the 2nd to the 3rd MON of February
- **BREAKING CHANGE** Drop Support for Python 2 - EOL January 1st 2020 (#442).
- Added Ukraine calendar, by @apelloni.
- Small cleanup in the ``.travis.yml`` file, thx to @Natim.
**ISO Registry API Change**
- Changes in the ``registry.items()`` method API.
- This method is aliased to ``get_calendars()``. In a near release, the ``items()`` method will change its purpose.
- The ``get_calendars()`` method accepts an empty/missing ``region_codes`` argument to retrieve the full registry. Please see the [ISO Registry documentation](https://peopledoc.github.io/workalendar/iso-registry.html) for extensive usage docs (#403, #375).
