UPDATE: It seems like the official Android 5.0 Lollipop roll out for Nexus 4 and Nexus 5 devices has been delayed with a week due to a Wi-Fi Battery drain bug. Now the roll out should take place next week on November the 12th after the bug will be completely fixed and when Google is sure that the new Android 5.0 Lollipop OS will run smoothly for all devices.
Google has launched the final repositories from Android 5.0 Lollipop for AOSP development for the Nexus 4, Nexus 5 and Nexus 6 smartphones. All the custom ROM developers can start cheering as they will be able to work with these new Lollipop features before the final Android 5.0 Lollipop upgrade is released.
Starting today we will see the official Android 5.0 Lollipop on the Nexus 6 and Nexus 9 devices, while the rest of the Nexus are still waiting for Google to release the updates or the Android 5.0 factory images. This new update from Google is probably the biggest overhaul ever released for Android devices.
With the Android 5.0 Lollipop released for AOSP we can expect developers to start work on releasing custom Lollipop ROMs before the end of this month. This means that CyanogenMod, Paranoid Android, AOKP and all the other major custom ROM developing teams should post soon enough details about their Android 5.0 future plans.
Android 5.0 Lollipop comes with tons of great new features and improvements such as the Material Design UI, Notifications overhaul, new quick settings support, wallpapers, full Android Runtime support and more. However, all the Lollipop interface elements and features should be adapted by all the custom ROM developers as they wish, so we should be in for multiple Android 5.0 releases that are very differently looking one from another. Tell us in comments what you hope to see in these custom ROMs and which is the one custom ROM developing team that you think it will integrate Android 5.0 the fastest.
The Nexus 6 repositories website can be found here. In case you want to develop custom ROMs and other customizations based on Android 5.0 Lollipop for the older Google smartphone models then you can find the repositories here for Nexus 5 and here for Nexus 4. Now that these Android 5.0 files for AOSP are out there and ready for download we can start hoping that the final Lollipop updates isn't too far away for all Nexus devices.
