• Various build and portability improvements.

Version 2.6.1

2020-12-15

• No longer report zero width for category Sk (#167).

• cmake support improvements (#173).

Version 2.4

2019-05-10

Version 2.3

2019-03-30

• Unicode 12 support (#148).

• New function utf8proc_unicode_version to return the supported Unicode version (#151).

• Simpler character-width computation that no longer uses GNU Unifont metrics: East-Asian wide characters have width 2, and all other printable characters have width 1 (#150).

• Fix CHARBOUND option for utf8proc_map to preserve U+FFFE and U+FFFF non-characters (#149).

• Various build-system improvements (#141, #142, #147).

Version 2.2

2018-07-24

• Unicode 11 support (#132 and #140).

• utf8proc_NFKC_Casefold convenience function for NFKC_Casefold normalization (#133).

• UTF8PROC_STRIPNA option to strip unassigned codepoints (#133).

• Support building static libraries on Windows (callers need to #define UTF8PROC_STATIC) (#123).

• cmake fix to avoid defining UTF8PROC_EXPORTS globally (#121).

• toupper of ß (U+00df) now yields ẞ (U+1E9E) (#134), similar to musl; case-folding still yields the standard "ss" mapping.

Version 2.1.1

2018-04-27

• Fixed composition bug (#128).

• Minor build fixes (#94, #99, #113, #125).

Version 2.1

2016-12-26:

• New functions utf8proc_map_custom and utf8proc_decompose_custom to allow user-supplied transformations of codepoints, in conjunction with other transformations (#89).

• New function utf8proc_normalize_utf32 to apply normalizations directly to UTF-32 data (not just UTF-8) (#88).

• Fixed stack overflow that could occur due to incorrect definition of UINT16_MAX with some compilers (#84).

• Fixed conflict with stdbool.h in Visual Studio (#90).

• Updated font metrics to use Unifont 9.0.04.

Version 2.0.2

2016-07-27:

• Move -Wmissing-prototypes warning flag from Makefile to .travis.yml since MSVC does not understand this flag and it is occasionally useful to build using MSVC through the Makefile (#79).

• Use a different variable name for a nested loop in bench/bench.c, and declare it in a C89 way rather than inside the for to avoid "error: 'for' loop initial declarations are only allowed in C99 mode" (#80).

Version 2.0.1

2016-07-13:

• Bug fix in utf8proc_grapheme_break_stateful (#77).

• Tests now use versioned Unicode files, so they will no longer break when a new version of Unicode is released (#78).

Version 2.0

2016-07-13:

• Updated for Unicode 9.0 (#70).

• New utf8proc_grapheme_break_stateful to handle the complicated grapheme-breaking rules in Unicode 9. The old utf8proc_grapheme_break is still provided, but may incorrectly identify grapheme breaks in some Unicode-9 sequences.

• Smaller Unicode tables (#62, #68). This required changes in the utf8proc_property_t structure, which breaks backward compatibility if you access this struct directly. The functions in the API remain backward-compatible, however.

• Buffer overrun fix (#66).

Version 1.3.1

2015-11-02:

• Do not export symbol for internal function unsafe_encode_char() (#55).

• Install relative symbolic links for shared libraries (#58).

• Enable and fix compiler warnings (#55, #58).

• Add missing files to make clean (#58).

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).
