8.3

• NEW: bre: Add the binary properties Any, Assigned, and ASCII, which UTS #18 requires but the Unicode
  Character Database does not define. ASCII was previously only available as an alias of the Basic_Latin block.
• NEW: bre: Allow an initial Is on General Category values (\p{IsLu} or \p{gc=IsLu}) and on property names
  (\p{IsGC=Lu} or \p{IsAlphabetic=Yes}), as Unicode allows, per UAX #44.
• FIX: bre: Fix the inverse of the No_Block block property (\P{No_Block}) not including the
  Supplementary Private Use Area blocks (U+F0000 to U+10FFFF).
• FIX: bre: Fix negated Unicode properties and POSIX classes (\P{Lu}, \p{^Lu}, [[:^upper:]]) matching
  both cases of the characters in the property when using IGNORECASE. Character sets that contain negated
  properties are now expressed as alternatives ([a\P{Lu}] becomes (?:[a]|[^...])).
• FIX: bre: Fix an error when negating a binary property alias that has a value (\P{Alpha=No}).
