I run 1.9.4 and have been quite happy with what it does.
I upgraded to 1.9.6; I understand the big changes happened in 1.9.5 though.
My main issue with this is that there is no longer any possibility to modify the appearance of the text in the admin panel (modify the css). Apparently one now has to do that directly in a file.
I do not want to (nor am I technically proficient enough) to go manipulating the files directly.
So now I no longer have any possibility to modify the text's appearance. I find that a pity and hope that you will reintroduce the possibility to modify the css in the admin panel. (Or even better: have some more user-friendly way to change the look/size of the text.)
For this reason (and for this reason only) I reverted back to 1.9.4.
