Scintilla 5.5.7 released

[Neil Hodgson]

Scintilla is a cross-platform source code editing component.

Scintilla 5.5.7 is now available from the scintilla.org web site.

This is a feature and fix release.

SCI_SCROLLVERTICAL added to set view position and maintain it while performing line wrapping. Platform layers should be updated to call Editor::SetVerticalScrollPos from their override.

Storing scroll position in undo selection history can be controlled with SC_UNDO_SELECTION_HISTORY_SCROLL. Since this changes default to not saving, application may need to be updated to maintain current behaviour.

SC_MARK_BAR made slightly wider in many cases.

Images in autocompletion lists may be scaled to match high DPI on GTK and Qt with SCI_AUTOCSETIMAGESCALE.

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.

Scintilla uses Mercurial (Hg) for source code control. The repository can be cloned with
hg clone http://hg.code.sf.net/p/scintilla/code scintilla

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