When I use the command "title" or the command "testfor", it doesn't work(in MC 1.8.8 it work) and when i use something in the secondary hands for destroy, it doesn't work.
(Sorry for my bad english, I'm italian.)

To the second point, that is MC-83460
In the first snapshot i can, with the second hand, place and destroy blocks, at the snapshot 15w35e it isn't possible.
Destroying is only posible with the main hand...
1. don't submit multiple bugs in one report
2. you now require quotes at all json keys/values
3. the off hand cannot attack/mine, that's intended, only the main hand can attack/mine
