Because the release was probably rejected due some really painful bugs. System was barely responding and so on. I really had fun with it - updated with CyanDelta - and thought: Jesus - something really messed up my system. Now I'm back to the Nightly from March 17th.

That's interesting - I'm running the nightly from the 19th, updated with CyanDelta and all seems to be running fine.

@vedko: I also noticed this weird behavior in my thread @android-hilfe. Some have it, some not. I really don't know why. I thought, this maybe is from using Hulk-Kernel, but since others are running the update from 19th & also using the same version of Hulk, I gave up to find the problem. All I know: I'll wait until an official update gets released.

By dirty flash do you mean wiping only system or nothing at all?

Also, and sorry if I should be asking in a different thread, is anyone using a custom kernel with this new version?

    CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.0.2 (Lollipop), which is designed to increase performance and reliability over stock Android for your device.​

    CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    We have de-unified the Galaxy S4 line. Too many issues with having them all in one and a maintainer's nightmare. Look for jfltexx builds now as opposed to the jflte builds you previously used.

    The CyanogenMod team would like to thank everyone involved in helping with testing, coding, debugging & documenting! Enjoy!

    This is not the place to talk about custom kernels, don't report bugs/errors if you use one.

    I know that me and @alucard_24 work together on our custom ROM but this is official CM.

    Original Alucard kernel isn't updated with new stuff, this means broken sensors etc. Only Alucard in our CM custom builds is updated for now (we had to test it, that's why you still don't have an update available)

    GPE system size is being fixed in upcoming build

    For those having a greenish screen on latest nightly:
    Go to Settings -> Display & LED -> LiveDisplay -> Color calibration and set all sliders to about 50% (I have red=50%, green=47%, blue=51%)
    Then press OK, switch off the screen (power button) and switch on again -> voilà, natural colors!
    Till 1st lollipop snapshot is released :D:D
