OK, that's cool. Haven't yet got into testing it anyway.
1. This is too late for 4.8 release.
2. I'm on four week leave starting from week after next week but before
I go to my leave I will apply these commits to my master branch so that
they get exposure.
3. I try to do testing for my part before going to the leave.
