“If you are on CM 12.1 YOG4P or CM 12.1 YOG7D releases, we recommend you stay on course with the SNAPSHOT release channel and not jump to nightlies unless you are willing to accept a dip in quality. Our stable branches are vetted, CTS run and (in some cases) shipped on retail devices – which means the quality of those branches is far and above that of nightlies. We’d advise these folks to stay on the SNAPSHOT train, and we’ll have a quality approved SNAPSHOT for CM13 sometime Jan”.
