v4.2.0-beta4

Hopefully last beta of this series! I know it's a beta and I shouldn't be pushing new big features, but... 👼 I had this in my sleeve for some time and I wanted to field-test it: the conversations list has been ported to RecyclerView, with all the improvements that it brings: improved performance, smoother change transitions, nice animations and an overall better user interface. I hope you like it 🎉
