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 1.1.2

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.

Version 1.1.1

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.

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)

2006-12-26:

Version 1.0.1

2006-09-20:

• included a gem file for the ruby version of the library

Release of version 1.0.1

Version 1.0

2006-09-17:

• added the LUMP option, which lumps certain characters together (see lump.md) (also used for the 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 occurred when compiler optimization was switched on

Version 0.2

2006-06-05:
