Do not worry, we still have power left for OpenPlotter 4 
As you can read in the docs, we always need a new major version of OpenPlotter when Debian officially releases a new major release and Raspberry OS releases a new major release based on this Debian release. So, we are already there, Raspberry 5 will need a new version of Raspberry OS based on Debian Bookworm and we will release OpenPlotter 4 based on Raspberry OS Bookworm. This time OpenPlotter 4 will work only for 64 bits.
You all are right. OpenPlotter 3 needed a lot of changes because some applications were not even in stable state and some breaking changes were waiting for a major release to be applied. This time OpenPlotter 4 will just need some changes to adapt all the apps to the new OS, not big or breaking changes are waiting. It should be a smooth transition and we will start it when the dust of Raspberry 5 and Raspberry OS Bookworm has settled.
We are considering the changes in MacArthur HAT v.1.1 required to work in Raspberry 5 as well but without having a Raspberry 5 in hand yet we can see only few potential issues easily solved even with the current design. More info soon.
