Project scale and scope. edX does most of its development in public repos. Not all of the features and functionality are used by every open source user. The scale of edX’s user base is so much larger than others’ that edX finds issues well before other users. Also, by the time a formal Open edX release is announced, edX has run the code for weeks or months.
