The changelog can be found in the release section


In Mosby 3.0 we have changed the package name from

(note the 3 at the end). Migrating a Mosby 2.x based app to Mosby 3.0 should be straightforward: Just replace all import statements of your app in android studio with
Edit -> Find -> Replace in Path ...
and set find
import com.hannesdorfmann.mosby
replace with
import com.hannesdorfmann.mosby3
. There were also some minor API changes (see changelog), but most apps should be fine by replacing the import statements.


Mosby has a plugin for Conductor. You can find it here:
