v2.0.0

Compare Source

2025-06-19

Breaking:

• In order to implement UAX#44
  (see below) we had to change code generated by unicode_names2_generator in a way that
  was not compatible with unicode_names2 v1.3.0 (and vice-versa), forcing us to bump
  unicode_names2_generator to v2.0.0. In order to keep them in sync, unicode_names2
  is bumped accordingly.
  Additionally, implementing UAX#44 might break code if it relies on this crate for some
  sort of validation.

Feature:

• Implement UAX#44
  to make name matching less strict. (#​46)

Internal:

• Remove unused dependencies (#​42)

We probably need to bump to unicode 2 first. We should align it with the most recent supported Python version and whatever unicode standard that version uses
