With CM10, the CyanogenMod team started pushing out M-Series releases, which are designed to be a more stable alternative to nightly builds. In fact, CM cites these builds as being "mostly stable and ready for everyday use."
We saw two runs of M builds show up for CM10, which were followed by the stable release a few weeks later. Now, the team has released the first M build of CM10.1 for several devices:
- Samsung Captivate
- Samsung Nexus S (+4G)
- Samsung Galaxy S3 USA models (D2*)
- Samsung Galaxy S (galaxysmtd/galaxysbmtd)
- Google Nexus 7
- Google Galaxy Nexus (all variants)
- Google Nexus 4
- Google Nexus 10
- ODroid U2
- Samsung P3100, P3110
- Samsung P5100, P5110
Of course, this is just a starter list and more devices will be added in the coming days/weeks.
