-2006-06-02:
-- initial release of version 0.1
-
-2006-06-05:
-- changed behaviour of PostgreSQL function to return NULL in case of
-  invalid input, rather than raising an exceptional condition
-- 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
-
-Release of version 0.3
-
-
-2006-09-17:
-- added the LUMP option, which lumps certain characters together
-  (see lump.txt) (also used for the PostgreSQL "unifold" function)
-- added the STRIPMARK option, which strips marking characters
-  (or marks of composed characters)
-- deprecated ruby method String#char_ary in favour of String#utf8chars
-
-Release of version 1.0
-
-
-2006-09-20:
-- included a gem file for the ruby version of the library
-
-Release of version 1.0.1
-
-
-2006-09-21:
-- included a check in Integer#utf8, which raises an exception, if the given
-  code-point is invalid because of being too high (this was missing yet)
-
-2006-12-26:
-- added support for PostgreSQL version 8.2
-
-Release of version 1.0.2
-
-
-2007-03-16:

-  empty string at grapheme cluster boundaries (method String#utf8chars).
-
-Release of version 1.0.3
-
-
-2007-06-25:
-- Added a new PostgreSQL function 'unistrip', which behaves like 'unifold',
-  but also removes all character marks (e.g. accents).
-
-2007-07-22:
-- Changed license from BSD to MIT style.
-- Added a new function 'utf8proc_codepoint_valid' to the C library.

-  included in the distribution.
-
-Release of version 1.1.1
-
-
-2007-07-25:
-- Fixed a serious bug in the data file generator, which caused characters
-  being treated incorrectly, when stripping default ignorable characters or
-  calculating grapheme cluster boundaries.

-Release of version 1.1.2
-
-
-2008-10-04:
-- Added a function utf8proc_version returning a string containing the version
-  number of the library.
