Hi Christopher,
The timeline on new RiR components is subject to the dev priorities/workload, there are weekly fixes and some components being added but the majority of the focus at the moment is on Rhino 8 integration (GH1 components) & stop ship items. Hard for me (and the devs) to say when that will change to allow more work on highly requested Revit API components such as the Analytical, MEP Systems & Curtain Walls.
