utf8proc release history

Version 1.3

2015-07-06:

Updated for Unicode 8.0 (#45).
New utf8proc_tolower and utf8proc_toupper functions, portable replacements for towlower and towupper in the C library ([#40]).
Don't treat Unicode "non-characters" as invalid, and improved validity checking in general ([#35]).
Prefix all typedefs with utf8proc_, e.g. utf8proc_int32_t, to avoid collisions with other libraries ([#32]).
Rename DLLEXPORT to UTF8PROC_DLLEXPORT to prevent collisions.
Fix build breakage in the benchmark routines.
More fine-grained Makefile variables (PICFLAG etcetera), so that compilation flags can be selectively overridden, and in particular so that CFLAGS can be changed without accidentally eliminating necessary flags like -fPIC and -std=c99 (#43).
Updated character-width tables based on Unifont 8.0.01 (#51) and the Unicode 8 character categories (#47).

Version 1.2

2015-03-28:

Updated for Unicode 7.0 (#6).
New function utf8proc_grapheme_break(c1,c2) that returns whether there is a grapheme break between c1 and c2 (#20).
New function utf8proc_charwidth(c) that returns the number of column-positions that should be required for c; essentially a portable replacment for wcwidth(c) (#27).
New function utf8proc_category(c) that returns the Unicode category of c (as one of the constants UTF8PROC_CATEGORY_xx). Also, a function utf8proc_category_string(c) that returns the Unicode category of c as a two-character string.
cmake script CMakeLists.txt, in addition to Makefile, for easier compilation on Windows (#28).
Various Makefile improvements: a make check target to perform tests (#13), make install, a rule to automate updating the Unicode tables, etcetera.
The shared library is now versioned (e.g. has a soname on GNU/Linux) (#24).
C++/MSVC compatibility (#17).
Most #defined constants are now enums (#29).
New preprocessor constants UTF8PROC_VERSION_MAJOR, UTF8PROC_VERSION_MINOR, and UTF8PROC_VERSION_PATCH for compile-time detection of the API version.
Doxygen-formatted documentation (#29).
The Ruby and PostgreSQL plugins have been removed due to lack of testing (#22).

Version 1.0.3

2007-03-16:

Fixed a bug in the ruby library, which caused an error, when splitting an empty string at grapheme cluster boundaries (method String#utf8chars).

Version 1.0.2

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)

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 occurred when compiler optimization was switched on

Version 0.2

2006-06-05:

changed behaviour of PostgreSQL function to return NULL in case of invalid input, rather than raising an exceptional condition
