Thanks from me too. I'm running 14.01 (stable) under the wine Windows emulator on Linux - and getting a crash, which I trace back to Cura/gui/util/webcam.py/vidcap.pyd in the backtrace. Cura is able to detect my controller (ttyUSB0) but seems to not play well with the Linux webcam under wine's emulation.
I was hoping the stable release would avoid other problems - now it looks like I'll have to grab it as soon as it is out.
