# 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]).
|
||
|
|
|
||
