Changelog

2006-06-02:
- initial release of version 0.1

2006-06-05:
- changed behaviour of PostgreSQL function to return NULL in case of

- improved efficiency of PostgreSQL function (no transformation to C string
  is done)

2006-06-20:
- added -fpic compiler flag in Makefile
- fixed bug in the C code for the ruby library (usage of non-existent
  function)

Release of version 0.2

2006-07-18:
- changed normalization from NFC to NFKC for postgresql unifold function

2006-08-04:
- added support to mark the beginning of a grapheme cluster with 0xFF
  (option: CHARBOUND)
- added the ruby method String#chars, which is returning an array of UTF-8
  encoded grapheme clusters
- added NLF2LF transformation in postgresql unifold function
- added the DECOMPOSE option, if you neither use COMPOSE or DECOMPOSE, no
  normalization will be performed (different from previous versions)
- using integer constants rather than C-strings for character properties
- fixed (hopefully) a problem with the ruby library on Mac OS X, which
  occured when compiler optimization was switched on

2006-09-17:
- added the LUMP option, which lumps certain characters together
  (see lump.txt) (also used for the PostgreSQL "unifold" function)

  (or marks of composed characters)
