New version of Tmux (2.2) breaking vim tmux plugins (like vim-tmux-runner)

Is anyone having trouble with the latest version of tmux?

Both vim-tmux-runner and vimux / vroom seem to have stopped working.

Not sure why.

Anyone else have this problem?

I’m still on older tmux myself, but I’ve not heard of this issue. Would you mind creating an issue on vim-tmux-runner and I can take a look?
