I think putting out a 2.5.4 sooner rather than later is good idea.

We can decide afterwards about jline, and whatever outcome can be implemented for 2.5.5, which I imagine will be the last of the 2.5 line.

I will write separately about the jline issues, where I think we stand, and some possibilities for what we can do about it.
