It must be noted that the second CyanogenMod “M Series” build which was originally due to be released this week clashed with the 4.1.2 release, so Cyanogen himself decided to postpone the M Series build for another week at the minimum in order to consolidate the remainder of the changes. This should not be too much of an issue, as good things always come to those who wait, although it must be noted that some folks do want to switch over to M Series builds which are touted to be more stable instead of relying on nightlies.
