New in 0.9.8:
* The data tables and line breaking algorithm have been updated to Unicode
version 9.0.0.
* In the include file unigbrk.h, the function uc_grapheme_breaks has
been added to accommodate the new UAX#29 rules involving 3 or more
consecutive characters.
New in 0.9.7:
* The license has changed from LGPLv3+ to "LGPLv3+ or GPLv2"
New in 0.9.6:
* The data tables and line breaking algorithm have been updated to Unicode
version 8.0.0.
New in 0.9.5:
* The data tables and line breaking algorithm have been updated to Unicode
version 7.0.0.
* In the include file uniname.h, the function unicode_name_character
has been extended to look for name aliases.
New in 0.9.4:
* The data tables and line breaking algorithm have been updated to Unicode
version 6.0.0.
* A new include file unigbrk.h is provided. It declares functions for
grapheme cluster breaking, that is, determining the boundaries between
graphemes. See the documentation chapter "Grapheme cluster breaks in strings"
for details.
* In the include file unictype.h, constants are defined for the group of
general categories LC ("Cased Letter").
* In the include file unictype.h, functions for associating canonical
combining classes with names have been added:
uc_combining_class_name
uc_combining_class_long_name
uc_combining_class_byname
* In the include file unictype.h, functions for the Arabic joining type and
the Arabic joining group have been added:
uc_joining_type_name
uc_joining_type_long_name
uc_joining_type_byname
uc_joining_type
uc_joining_group_name
uc_joining_group_byname
uc_joining_group
* In the include file unictype.h, functions for new predefined properties
have been added:
uc_is_property_cased
uc_is_property_case_ignorable
uc_is_property_changes_when_lowercased
uc_is_property_changes_when_uppercased
uc_is_property_changes_when_titlecased
uc_is_property_changes_when_casefolded
uc_is_property_changes_when_casemapped
But it's recommended to use the case mapping functions from unicase.h
instead.
* In the include file unictype.h, the functions for bidi class, formerly known
as bidirectional category, have been renamed:
uc_bidi_category_name -> uc_bidi_class_name
uc_bidi_category_byname -> uc_bidi_class_byname
uc_bidi_category -> uc_bidi_class
uc_is_bidi_category -> uc_is_bidi_class
The old function names still exist, but are obsolete.
* In the include file unictype.h, functions for returning long names of
property values have been added:
uc_general_category_long_name
uc_bidi_class_long_name
The functions
uc_general_category_byname
uc_bidi_class_byname
have been extended to recognize long names as well as short names.
* It is now easier to detect the subminor version: The value of the variable
_libunistring_version and of the macro _LIBUNISTRING_VERSION now includes
also the subminor version.
* The functions u8_mbtouc and u8_mbtouc_unsafe now handle ill-formed UTF-8
input in a better way, that is more compliant with W3C recommendations.
* The functions u8_strcoll, u16_strcoll, u32_strcoll now produce results that
are less dependent on the iconv implementation in use.
* The functions u8_strstr, u16_strstr, u32_strstr now perform in O(n) time
worst-case, where n is the sum of the lengths of the argument strings.
New in 0.9.3:
* Bug fixes in unistr.h functions:
- The functions u16_to_u32, u16_to_u8, u8_to_u32, u8_to_u16 now fail when
the argument is not valid. Previously, they returned a converted string
where invalid parts were each replaced with U+FFFD.
- The function u8_mbsnlen now counts an incomplete character at the end
of the argument string as 1 character. Previously, it could count as 2
or 3 characters.
- The return value of the u8_stpncpy, u16_stpncpy, u32_stpncpy functions
was incorrect.
- The u8_strcoll, u16_strcoll, u32_strcoll now try harder to give a non-zero
return value.
* Portability to MacOS X 10.6 and Cygwin 1.7.
New in 0.9.2:
* The function uc_locale_language now uses the locale of the current thread,
if a thread-specific locale has been set.
New in 0.9.1:
* In the include file unicase.h, functions for case mapping of substrings have
been added.
New in 0.9:
* The new include file unicase.h implements case folding.
* The new include file uninorm.h implements normalization.
* The new include file uniwbrk.h implements word break determination.
* The library source code is now part of gnulib.
