The CyanogenMod team recognizes that it’s tough to keep up with all of the nightly builds and rapid release of builds. They also understand that if they don’t keep their foot on the gas with new releases, someone else is going to take their code and do it themselves. Unfortunately, this can create a less-than-desired experience and lead to a bad taste for modding. To combat this, the CyanogenMod team has announced M-Series releases.
M-Series builds will be done at the beginning of every month. We did a soft freeze of the codebase for the last week, blocking new features in order to stabilize. Our plan is to continue this (assuming that the response is good) up until stable release, and onward. M-Series builds will be available under the EXPERIMENTAL tag. The filename will include the date stamp as well as the M version. These builds should be stable enough for daily use, and we encourage feedback and bug reports.
It’s not quite clear what the “M” stands for in M-Series, and even the CyanogenMod team doesn’t have a solid answer. So, name it whatever you want, just be sure to look for it at the start of each month. As of today the list of devices supported with an M-Series release is at eighteen models so be sure to check at get.cm!
