Changelog

1.0.22

• Move to semantic version numbering, no longer following version
  numbers from the original Perl module. This fixes an issue with
  setuptools (>= 8) and others expecting major.minor.patch format.
  (Move to semantic versioning avian2/unidecode#13)
• Add transliterations for currency signs U+20B0 through U+20BF
  (thanks to Mike Swanson)
• Surround transliterations of vulgar fractions with spaces to avoid
  incorrect combinations with adjacent numerals
  (thanks to Jeffrey Gerard)
