This is the module definition for Rawtherapee. It's pretty simple, so there shouldn't need to be many changes. See for the RPMs.

There are two streams: devel and stable. The stable stream tracks upstream releases closely, after some basic testing. We may also include critical security fixes, but again in general we follow an upstream-first model.

The devel stream is less cautious. We may include release candidates, nightly builds, or other experimental / in-development builds.
