Tonight, when everyone else is sleeping, the folks over at CyanogenMod are hard at work, as always. The team just announced a brand new addition to the slew of CM releases: M-Series. From now on (provided the community approves), the team will begin rolling out builds that are "a bit more stable" at the beginning of every month. Prior to this initial release of CM10-M1, the group did a "soft freeze of the codebase" in an attempt to stabilize the builds, so these should be more reliable than your average release.

Here's the list of devices that builds are currently available for:


  • Galaxy Nexus GSM (maguro)
  • Galaxy Nexus VZW (toro)
  • Galaxy Nexus Sprint (toroplus)
  • Galaxy S2 GT-I9100G (i9100g)
  • Galaxy S (galaxysmtd)
  • Galaxy S B (galaxysbmtd)
  • Captivate (captivatemtd)
  • Galaxy S3 Sprint (d2spr)
  • Galaxy S3 VZW (d2vzw)
  • Galaxy S3 AT&T (d2att)
  • Galaxy S3 TMO (d2tmo)
  • Galaxy S3 US Cellular (d2usc)
  • Nexus S (crespo)
  • Nexus S 4G (crespo4g)
  • Galaxy Note AT&T (quincyatt)
  • Google Nexus 7 (grouper)
  • Sony Xperia Acro S (hikari)
  • Sony Xperia S (nozomi)

As always, nightlies will continue to be available, but for the slightly less adventurous among you, this effort should provide a healthy middle ground between bleeding edge, and waiting on stable RCs for your device. It will also help casual users keep a frame of reference for the progression of everyone's favorite ROM. If you'd like to get in on the action, you can download the M1 builds here.

So, what do you think? Is this is a good move? Or would you rather just stick to nightlies, release candidates, and regular stable releases? As we said before, the CM team is going to decide whether to continue the M-Series project based on community feedback, so feel free to weigh in both here and on the CyanogenMod forums.

    M as in Milestone?

    • Astria

      quoted directly from CM blog

      We aren’t exactly sure what M stands for. “Monthly”, “milestone”, or perhaps “MINE ALL MINE!”.

    More options is rarely ever a bad thing. If I were switching to a new phone I would likely start with one of these M-releases... then go crazy with a nightly shortly thereafter.

    Why no love for GS3 International :(

    • William Curin

      They're waiting on kernel sources from Samsung. As it is right now a bunch of JB features don't work right and there's a pretty horrible memory leak.

  • Tee

    No support for Buffalo routers???

    Seriously, this is a good move. I personally have avoided CM just because of the nightlies and the lack of stable ROMs for my SGS. These M-files are a good compromise to me.

  • VonLaserface

    I'm a little surprised to see the AT&T GNote on that list. I'm curious how much of a difference it will make.

  • John

    I'm a fan & think this is a good move on their part. I flash their nightlies fairly often on my Galaxy Nexus, and I've never had any issues. It's rare that I have to do a clean flash anymore, so it gives me a nice in between build if I ever choose to clean flash again on CM10.

    • fixxmyhead

      dont u get bored flashing on the galaxy nexus? i bought my wife one and the stock rom is fast enough, no problems and have yet to see it strutter. only thing i could think of to be on cm10 would be for like battery mods or toggles

      • John

        naw, not really. i work in IT & like to play with my toys a lot. i use roms mainly b/c of the extra customization options. lockscreen shortcuts & notif. toggles are the biggest ones that i utilize.

      • Sxeptomaniac

        I'm similar, in that I like tinkering, but I also like getting updates ahead of the glacial OTA ones. Being in IT, it sometimes helps to be able to know where the OS is heading before it hits a wider release, since I'm comfortable with it before I start getting calls on how to do things at work and from a few family/friends.

  • David Keith

    lets be honest. I will still continue to flash nightlies so this doesn't matter to me what so ever.

  • Joe

    It's a good move. I will continue to flash nightlys, but those who did shay away because of certain "instabilities" may reconsider now.

  • jammer

    People are reporting that the new M build for d2vzw is very fast compared to the previous nightly and that LTE starts up instantly at first boot. I might have to jump in the game now.

    I like this idea .. Some people are scared of nightlies, but RC's aren't monthly, so having this in-between release is a nice addition. Tho it will add confusion with bug reports : "What version are you on? nightly 20120910/09/08, M 1/2/3, or RC 1/2/3"

  • Jon

    So, why they develop for the way more reduced 9100G and ignore the international best seller Galaxy S2 GT-9100?? I still don´t get it.

    • rskyline

      It isn't about if is the best phone ever or is the best seller because they don't get any money from that right? Even isn't related to number of users. Is related directly to chipset. So your chip is Samsung you have to wait for them to release the sources. We the i9100G are blessed with a TI OMAP chip that isn't as powerful as Exynos but Texas Instruments do it better on Open source collaboration. We have the source for ti omap since the release of JB. You guys have to wait for Samsung..

  • L boogie

    hopefully this should be applied to tablets real soon

    • L boogie

      besides the nexus 7 that is

  • http://twitter.com/danlocker Daniel Locker

    Why the carrier phones first? Give the best sellers a look in.

  • Sxeptomaniac

    Great move! I need my phone somewhat stable for work and whatnot, so I've been monitoring CM and just hoping for an RC, but the M-release is awesome.

    In addition, I wouldn't mind dealing with minor problems and submitting feedback and bug reports, if that helps the CM team.

  • Tim

    Love it. I was on CM9 on my Captivate and was sure about the nightlies. When the M1 came out I gave it a shot. I was worried about performance, but so far, it has been all good.

  • Dimitrij

    I don't like this... The stable/RC's and Nightlies are enough.
