ksh 93u+m: KornShell lives! | Latest release: https://github.com/ksh93/ksh/releases

Project mention: Faster Shell Startup with Shell Switching | news.ycombinator.com | 2024-01-16

David Korn's ksh93 was passed on to a new set of developers, who attempted to release a new version; AT&T rolled back these changes due to performance problems which raised questions of support status. It does appear that ksh93 development has resumed, and a new version was released late last year.

The independent pdksh spawned mksh, which is the default shell used in Android (as it has a BSD license); mksh appears to be very much active.

OpenBSD also forked oksh from pdksh. This is certainly well-maintained.
