v3.1

- Ensure license is included in package (Thanks, Julien Schueller)
- No longer mark wheel has universal (Thanks, Matthieu Darbois)
- Test on PowerPC using Travis CI

v3.0

- Python 2 is no longer supported (the 2.x branch supports Python 2,
  use "idna<3" in your requirements file if you need Python 2 support)
- Support for V2 UTS 46 test vectors.

v2.10

- Update to Unicode 13.0.0.
- Throws a more specific exception if "xn--" is provided as a label.
- This is expected to be the last version that supports Python 2.

v2.9

- Update to Unicode 12.1.0.
- Prohibit A-labels ending with a hyphen (Thanks, Julien Bernard!)
- Future-proofing: Test on Python 3.7 and 3.8, don't immediately
  fail should Python 4 come along.
- Made BSD 3-clause license clearer

v2.8

- Update to Unicode 11.0.0.
- Provide more specific exceptions for some malformed labels.

v2.7

- Update to Unicode 10.0.0.
- No longer accepts dot-prefixed domains (e.g. ".example") as valid.
  This is to be more conformant with the UTS 46 spec. Users should
  strip dot prefixes from domains before processing.

v2.6

- Allows generation of IDNA and UTS 46 table data for different
  versions of Unicode, by deriving properties directly from
  Unicode data.
- Ability to generate RFC 5892/IANA-style table data
- Diagnostic output of IDNA-related Unicode properties and
  derived calculations for a given codepoint
- Support for idna.__version__ to report version
- Support for idna.idnadata.__version__ and
  idna.uts46data.__version__ to report Unicode version of
  underlying IDNA and UTS 46 data respectively.

v2.5

- Fix bug with Katakana middle dot context-rule (Thanks, Greg
  Shikhman.)

v2.4

- Restore IDNAError to be a subclass of UnicodeError, as some users of
  this library are only looking for the latter to catch invalid strings.

v2.3

- Fix bugs relating to deriving IDNAError from UnicodeError.
- More memory footprint improvements (Thanks, Alex Gaynor)
