It's actually running really really well! Posting this from the 1130 build now! One thing that did work on FML and just refuses to on cm12 is getting the APN to stick, it says "APN settings aren't available for this user" (which I think it also said in FML but still stuck after it was saved), otherwise everything else has been mentioned in the op as far as quirks are concerned

I'm getting much worse battery life than with the last CM11 nightly. Overnight battery drain was 3.7%/hour, compared to around 1%/hour with CM11. According to GSAM, the main issue was system(mediaserver) at about 94% of battery usage. No media was being served, so far as I can tell. EDIT: battery life often improves for me a day or two after installing a new generation, so I'll see if it gets better today.

I notice that the google bar at the top of the page always has: Say "OK Google." My Nexus 5 running stock doesn't have this.

It's also much laggier than CM11.

Video works with NuPlayer unchecked in Developer Options. Specifically, I could play video with MX player.

Possibly related to camera not working, the flashlight doesn't work. I only tried turning it on with quick settings.

No crashed so far and no app problems other than camera.

Tap and Go setup (against my N5), worked properly. It didn't work on FML.

I'm testing without a SIM at the moment, just wifi.

Thank you Ziyan

I had my SIM fried somehow after i flashed the rom yesterday, I had to replace the sim card today with a new one, the old one is toast.
It happened during "cellular network setup", it wanted my pin number, as soon as i entered it it was asking for my puk number.
Typed it in, things finished but without network connectivity, had the no sim card sign on the statusbar.
Could it be something connected to the rom or it was just my sim card time to go?

Cheers

Just want to say thanks!

Don't have enough posts to be allowed to post on the CM11 thread, so doing it here.

Ziyan,
Thank you so much for your work on this and I am looking forward to the first monthly CM12!

Try turning off ok google detection from the launcher settings - also, if you use the default launcher, set the app drawer animation to "none", because CM forgot to update that part of launcher to lollipop - they left in the animation from 4.4, so it's laggy and ugly. I just submitted the patch set to fix that, they merged it already so the next build will have this set by default.
Also, if you manage to break camera or video playback, I noticed it tends to leave the video processing part of the CPU active all the time until you reboot, so try that out too :)
As for the lag, it should improve over time.

There's no way a ROM could to that :eek:

I rebooted and recharged about two hours ago and battery is draining at 1.7%/hour (including listening to music, not just on idle). While it's usually a mistake to rely on short time periods, the prior drain could well have been due to breaking camera and video playback. I'll continue to monitor.

I'm using the google now launcher and like ok google detection. If I get down to similar idle battery drain as on CM11, I'll leave detection on, otherwise I'll test with it off.

I'd hope lag would improve as we go beyond early testing :p

Thanks

EDIT: battery drain on idle is going down a bit, suggesting your diagnosis of broken video leaving the CPU active was correct.

Same bug with PUK

Ok, I don't know which information matters but:
I'm in Germany.
Steps before flashing new ROM from the 30th:
-> wipe cache
-> wipe system
-> wipe dalvic
-> flash rom (everything from cwm)
While trying to flash gapps i got error code 6 (Which i found out later was a buggy version of CWM (6.0.4.7)) but I didn't care and rebooted.
Everything seemed to work, but a few seconds later he asked for the PIN (like always).
Typed PIN correctly, after the FIRST try, the phone asked for the PUK.
Now, after flashing a newer CWM and the most recent cm-11 nightly + gapps ... at least everything works again, except for the SIM cause i can't find my PUK ... well, gonna buy a new prepaid tomorrow. Still an interesting bug ... does anybody know how this could happen? Would be nice to use Lollipop, even if it's bugged as hell ^^

edit: Without SIM, the ROM looked awesome. I had no lag and any app worked. BUT the home button did not. ^^

    After countless unofficial builds and hours spent with this, I am happy to announce that maguro is now considered stable enough to get official CM12.1 nightlies :) moving on to CM13 after I find some time, which will hopefully become a nightly soon as well, since the hard part of the work is now done ;) updated the OP accordingly (the builds in the downloads section will stay up for a couple days, just in case there's a problem we need to compare with an older build).

    Sorry for not being active lately guys, I was busy, as my new semester just started :( but don't worry, I didn't forget my plans for this, I'll release a new build soon :)

    New build up. Changes:
    - reclaimed ~6 megabytes of userspace RAM
    - enabled video stabilization, exposure and whitebalance lock in the camera HAL (our ducati supports these, but it's not advertising it! what a *****...)
    - disabled dex2oat watchdog (this should make the optimizing apps dialog on every boot disappear, and hopefully fixes installing large apps)
    - synced with CM repos (01/01)

    I also switched back the default I/O scheduler to BFQ - I hope that the lockups some of you experienced were caused by an older CM bug (they made some BFQ-related platform changes).
    If anyone encounters another one, and wants to switch back, simply change sys.io.scheduler to cfq in /system/build.prop. Alternatively, use your favorite kernel settings app to change to CFQ on boot (but I'd recommend changing build.prop instead - I think Kernel Adiutor has a nice interface for editing it). And remember: if it locks up again, no need to remove the battery: just hold down the power button for at least 10 seconds, and the device will turn itself off.

    will 13 come :fingers-crossed:
    As soon as I'm satisfied with the results (currently, I'm not - looking at you, memory management).

    The folks over at the S3 camp are enjoying a nearly bugfree CM13 with 3.0 kernel. Funny if you look back at codewokx swearing while getting CM9 to work (camera was a pain).
    Facts:
    - they received official KitKat update with proper drivers and stuff, tuna only got 4.3 (Samsung updated their EGL blobs for KitKat, meaning they didn't have to port over to a new kernel like we did, and didn't have to switch to a newer camera and domx hal)
    - there's at least 10 people actively maintaining it over CM
    - their user and developer community is at least 10x bigger

    I can't express how hard and time-consuming it is to maintain tuna with only two active developers :(

    Just a heads up, the flashlight toggle has been fixed, but CM's ffmpeg **** broke the domx, so video playback is now gone, I already have the fix composed in my mind (lol), just need to test it... my finals are here, so I'm pretty busy now, but I'll try to fix and upload a new build in the next few days :)
