------------------

- The is_dst flag is wrong for Europe/Dublin on some Unix releases.
I changed to another way of determining if DST is in effect or not.

- Added support for Python 3.7 and 3.8. Dropped 3.5 although it still works.

------------------

- No differences since 2.0.0b3

------------------

- 1.5 had a bug that slipped through testing, fixed that,
increased test coverage.

----------------

- No longer treats macOS as special, but as a unix.

- get_windows_info.py is renamed to update_windows_mappings.py

- Windows mappings now also contain mappings from deprecated zoneinfo names.

----------------

- I use MIT on my other projects, so relicensing.

------------------

- Dropping support for Python versions nobody uses (2.5, 3.1, 3.2), adding 3.6
Python 3.1 and 3.2 still works, 2.5 has been broken for some time.

- Ayalash's OS X fix didn't work on Python 2.7, fixed that.
