Scintilla 5.5.8 released

[Neil Hodgson]

Scintilla is a cross-platform source code editing component.

Scintilla 5.5.8 is now available from the scintilla.org web site.

This is a feature and fix release.

Format for SCI_GETSELECTIONSERIALIZED changed. This format was documented as "may change" and it may change further.

Update display after undo when restoring selection.

Update case folding and character categorization data to Unicode 16.

Fix a bug when indenting a rectangular selection.

A C++17 compiler is required to build Scintilla. Microsoft Visual C++ 2022, GCC 9.0, Clang 9.0, Xcode 14 Clang or newer will work. Some slightly older compilers may still work.

A list of changes is available on the history page.

hg clone http://hg.code.sf.net/p/scintilla/code scintilla

Thanks to the contributors of code and documentation and to the testers.
