vector-0.11 changed the fundamental representation of streams, so updating Repa to work with it could be a hassle. I still need to do a proper triage.

I went through an excessively busy period last year and didn’t have time to work on it. Google groups also stopped sending me mails, so I didn’t see this message until now. “if an email falls in the forest and no one sees it.. yada yada”

There is also Repa 4 in Github now, but it needs more bake before it’s in a releasable state.

Is there a timeline for vector-0.12 support?

There was a PR a few weeks ago, but it didn’t pass all the tests. Requires investigation.

Repa really needs some love from someone actively using it. I’m happy to add maintainers if you want to work on it directly. I’ve mostly moved onto successor systems, but they’re not ready for production use yet.
