For me the different versions of 15.2 for PB360 have always worked quite steadily - only a few freezes for the last few months, which is acceptable. I can't imagine a contemporary device that doesn't freeze at all
even if it is created by Steve Jobs. Actually the first freezes came to my PB while on 14.2. Now, as a matter of fact since the official 15.2 release I haven't had any freezes. My fbreader is graynm76_fbreader180 0.9.2.
A small request. Could someone of the devs post the new English language file? Or even better, a file with only the differences from the previous version. There are a few new strings that need to be translated ...
