3.5

Fixed

• Incorrect CMake test for Python presence at build time

2.20

Fixed

• Incorrect CMake test for Python presence at buildtime

3.4

Fixed

• Inadvertent pessimization in compare_no_case
• Concepts rejecting Char * as eligible for addition to sys_string

3.3

Fixed

• CMake build now correctly handles when Python detected on the build machine is too old to be used
• Tests now run correctly with PyPy Python installation

2.19

Fixed

• Error on missing std::char_traits<const char> on newer compilers
• CMake build now correctly handles when Python detected on the build machine is too old to be used
• Tests now run correctly with PyPy Python installation

2.18

Fixed

• Unresolved symbols errors with GCC 10.2

3.2

Added

• sys_string can now be normalize()-ed to NFC and NFD.
• It is now possible to use ICU instead of internal data/code for case conversion, grapheme
  iteration and normalization. This makes those operations a tiny bit slower but saves
  ~100kB in a final executable if you use all of them.

Changed

• This library is now header only
• Speed improvements to case conversions, case insensitive comparisons and grapheme iteration.

Fixed

• Addressed some false positive sanitizer warnings.

2.17

Added

• sys_string can now be normalize()-ed to NFC and NFD (back-ported from version 3).

Changed

• Supported Unicode version has been bumped to 16 (back-ported from version 3).
• Speed improvements to case conversions and case insensitive comparisons (back-ported from version 3).

Fixed

• Addressed some false positive sanitizer warnings.

3.1

Added

• grapheme_view and graphemes adapter which provide ability to iterate over grapheme clusters in sys_string and any UTF range.

Changed

• Unicode data has been optimized for better size/speed balance
• sys_string_t::hash_type has been changed from unsigned to size_t on some platforms.

Fixed

• Invalid character access in unicode mappings.
• Crash when sys_string_builder is re-used after build() on Apple and Python platforms.
• utf_ref_view and utf_owning_view now actually work with forward and input underlying ranges
• MSVC warnings when using std::hash<sys_string>

2.16

Fixed

• Crash when sys_string_builder is re-used after build() on Apple and Python platforms.
• MSVC warnings when using std::hash<sys_string>

Changed

• sys_string_t::hash_type has been changed from unsigned to size_t on some platforms.
