Update: Note that the [Quaternions.jl](https://github.com/JuliaGeometry/Quaternions.jl) package is now actively maintained, and Rotations.jl depends on Quaternions.jl ([Rotations.jl#175](https://github.com/JuliaGeometry/Rotations.jl/pull/175)).  
See [[ANN] Quaternions.jl v0.7.0](https://discourse.julialang.org/t/ann-quaternions-jl-v0-7-0/91368) for more information.

> I’ve been trying to use `Makie.Quaternion` with `ReferenceFrameRotations.Quaternion` and I am beaten.

- Makie.jl should now use `Quaternions.Quaternion` ([Makie.jl/src/utilities  
/quaternions.jl](https://github.com/MakieOrg/Makie.jl/blob/f2970dcd77bc16f311f8bb3226ef7d716395b369/src/utilities/quaternions.jl#L1-L5)).
- There was an issue in ReferenceFrameRotations.jl. to be compatible with Quaternions.jl ([ReferenceFrameRotations.jl#25](https://github.com/JuliaSpace/ReferenceFrameRotations.jl/issues/25)).
