Sorry, I didn't manage to reply sooner. In general, I'd like to support Astro 5 of course. I just need to figure out a way to ensure backwards compatibility. Astro seems to break output directory settings in v5. A proper change would probably need to have separate test projects for v2-4 and v5. If you're still interested in v5 support, I'd be happy to merge a PR with proper tests.
