Log message:
py-idna: updated to 2.10

2.10:
- 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.

Log message:
py-idna: updated to 2.9

2.9:
- Update to Unicode 12.1.0.
- Prohibit A-labels ending with a hyphen.
- 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

Log message:
py-idna: update to 2.8.

2.8 (2018-12-04)
++++++++++++++++

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

Log message:
py-idna: updated to 2.7

2.7:
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.

Log message:
Updated py-idna to 2.6.

2.6 (2017-08-08)
++++++++++++++++

- 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.

Log message:
Updated py-idna to 2.5.

2.5 (2017-03-07)
++++++++++++++++

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

Log message:
Updated py-idna to 2.4.

2.4 (2017-03-01)
++++++++++++++++

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

2.3 (2017-02-28)
++++++++++++++++

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

Log message:
Updated py-idna to 2.2.

2.2 (2016-12-21)
++++++++++++++++

- Made some changes to the UTS 46 data that should allow Jython to get around
  64kb Java class limits. (Thanks, John A. Booth and Marcin Płonka.)
- In Python 2.6, skip two tests that rely on data not present in that
  Python version's unicodedata module.
- Use relative imports to help downstream users.

Log message:
Switch to MASTER_SITES_PYPI.

Log message:
Update py-idna to 2.1.

2.1 (2016-03-20)
++++++++++++++++

- Memory consumption optimizations. The library should consume significantly
  less memory through smarter data structures being used to represent
  relevant Unicode properties. Many thanks to Shivaram Lingamneni for this
  patch.
- Patches to make library work better with Python 2.6. The core library
  currently works however the unit testing does not. (Thanks, Robert
  Buchholz)
- Better affix all Unicode codepoint properties to a specific version.
