A minor update for Hops (version 0.11.1) is now available via the package manager.
A small fix was made to the rhino.compute project to change how child processes (ie. compute.geometry.exe) get spawn whenever the rhino.compute.exe is launched. This change was primarily made because of how a production environment handles http requests, but this change also affected how Hops gets launched from Grasshopper. Rhino.compute.exe now has a command line option called --spawn-on-startup whose default value is false. If you include this argument when you launch rhino.compute.exe then it will automatically launch a child process on startup.
Please see this thread for a little more detail on these recent changes.
