# utf8proc release history # ## 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 1.1.6 ## 2013-11-27: - PostgreSQL 9.2 and 9.3 compatibility (lowercase `c` language name) ## Version 1.1.5 ## 2009-08-20: - Use `RSTRING_PTR()` and `RSTRING_LEN()` instead of `RSTRING()->ptr` and `RSTRING()->len` for ruby1.9 compatibility (and `#define` them, if not existent) 2009-10-02: - Patches for compatibility with Microsoft Visual Studio 2009-10-08: - Fixes to make utf8proc usable in C++ programs 2009-10-16: ## Version 1.1.4 ## 2009-06-14: - replaced C++ style comments for compatibility reasons - added typecasts to suppress compiler warnings - removed redundant source files for ruby-gemfile generation 2009-08-19: - Changed copyright notice for Public Software Group e. V. - Minor changes in the `README` file ## Version 1.1.3 ## 2008-10-04: - Added a function `utf8proc_version` returning a string containing the version number of the library. - Included a target `libutf8proc.dylib` for MacOSX. 2009-05-01: - PostgreSQL 8.3 compatibility (use of `SET_VARSIZE` macro) ## 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. - Added a new function `utf8proc_codepoint_valid` to the C library. - Changed compiler flags in `Makefile` from `-g -O0` to `-O2` - The ruby script, which was used to build the `utf8proc_data.c` file, is now included in the distribution. ## 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: - added support for PostgreSQL version 8.2 ## 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) - added the `STRIPMARK` option, which strips marking characters (or marks of composed characters) - deprecated ruby method `String#char_ary` in favour of `String#utf8chars` ## Version 0.3 ## 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 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 - 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) ## Version 0.1 ## 2006-06-02: initial release of version 0.1 [#6]: https://github.com/JuliaLang/utf8proc/issues/6 [#13]: https://github.com/JuliaLang/utf8proc/issues/13 [#17]: https://github.com/JuliaLang/utf8proc/issues/17 [#20]: https://github.com/JuliaLang/utf8proc/issues/20 [#22]: https://github.com/JuliaLang/utf8proc/issues/22 [#24]: https://github.com/JuliaLang/utf8proc/issues/24 [#27]: https://github.com/JuliaLang/utf8proc/issues/27 [#28]: https://github.com/JuliaLang/utf8proc/issues/28 [#29]: https://github.com/JuliaLang/utf8proc/issues/29
