Just to inform you that gramps 4.2.0 is in a "testing stage and state" for the future major release. This will be the first branch started since migration to github (done some months ago).
If your are using Debian, Ubuntu, Mint, etc ...
- a beta1 package is also available for testing.
If you want to help, give a try.
Do not forget to make a backup, first.
And remember that it is not the official release.
So, testing with copy is welcome.
Note, we should be able to test DB upgrade via the "copy" function on DB manager.
