Sound advice is to pull code from the stable branch if you're concerned about stability and issues, it's exactly why we created it:

PEQ and EZ clear the master branch and usually KLS and I will discuss if master should be pushed over to the stable branch after PEQ or EZ have been running on it for a week. Lately it has been KLS and PEQ making these judgment calls as I've not been aggressive with code updates or any projects for that matter this summer
