Scintilla is a cross-platform source code editing component.
Scintilla 5.6.0 is now available from the scintilla.org web site.
This is a crash fix release.
When the window was sized to be narrower than the margins, an empty text area caused undefined behaviour in a call to std::clamp. This was noticed on Linux using g++ where the UB caused a crash but may have occurred on other systems.
There will be no new release of Lexilla as this crash was specifically in Scintilla.
A signed version of Scintilla.DLL is included in the SciTE Windows executable download that can be used by downstream projects. It is signed "Open Source Developer, Neil Hodgson".
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.
https://www.scintilla.org/ScintillaHistory.html
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.
