+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
