AFAIK there's no plan for a new stable release right now—at least nothing that's been announced. It’s a bit of a shame, really. The compiler has seen loads of improvements over the years, but without regular releases, it’s easy for people to assume the project isn’t moving forward.
If you check the official site, the last release is from 2021, and the latest news item is about Niklaus Wirth’s passing. That doesn’t exactly give off an active or thriving vibe, and it might even make people think Pascal is dead.
I totally get that the devs are working on this in their spare time and out of passion, and I really respect that. But more frequent releases would help a lot. It’d show the project’s alive and well, attract more users, and maybe even bring in some backing to keep things going strong.
