I would like to start using C++20 in SciTE as it is mostly well supported now on current platforms. While there are no major benefits available from C++20, there are plenty of minor improvements.
The biggest C++20 feature, modules, is still poorly and unevenly supported across platforms so probably cannot be used.
Windows XP is currently built with some archaic tools and I don't think these will work with C++20 so Windows XP will not be supported. Mainstream support for Windows XP ended in 2009 and extended support ended in 2014. It may still be possible to use gcc for Windows XP but I won't be distributing executables.

The current 5.4.3 release will remain available and linked from the download page.

The question of 32-bit support has also been discussed but I don't think it's time yet to drop 32-bit builds.

I'm curious, which C++20 features would you like to use?

Csaba:

Initially, I expect to use std::span to remove some raw pointers, additional constexpr and similar for constraining code behaviour. Later, ranges and concepts. Eventually, modules when they're ready

I'm a C++ developer and I agree with this message.

The makefiles and projects have been changed to specify c++20 with this commit.
A single use of a C++20 API (starts_with) was included in FilePath.cxx with this commit.
This change should produce a diagnostic if any makefile, project or similar doesn't specify c++20.
It showed diagnostics on Win32, macOS, and Linux when the previous build files were executed.
