New and changed features in the 0.5 release are:

• Implementations of NFC normalization (toNFC and isNFC functions).
• Addition of a new GRAPHEMES string type. TEXT auto-normalizes to NFC at creation time (this includes the results of operations and built-ins), while GRAPHEMES does perform any automatical normalization. Both GRAPHEMES and TEXT can be used as targets when opening a Unicode-enabled stream.
• Implement loose matching for property names (UNICODE BIF).
• Implement all tests in NormalizationTest.txt, consistency check on ccc and canonical decomposition.
• InspectTokens: add options to select different dialects, specify default in the help display.
• New rxutry.rex utility, a modification of rexxtry.rex with Unicode support.
• Options DefaultString and Options Promote can be set by the caller. Make Options DefaultString TEXT the default.
• Added a new helpfile detailing how to use some of the TUTOR-generated data files from Classic Rexx dialects like Regina.

Bugs fixed:

• Fix bug #6
• RXU: do not translate BIF names after a twiddle.

Documentation additions and enhancements:

• Document the Unicode.Normalization class.
• Document many of the properties currently implemented by the UNICODE BIF.
• Move notes for old releases to separate files in the doc subdirectory.
• Improve the docs for the PersistentStringTable class, and move them to a separate helpfile.
