Google began pushing the Android 4.2.2 code to the Android Open Source Project (AOSP) a short while back, however as of today it looks like that roll-out has been completed. Simply put, this means you will be able to grab builds for all the current generation Nexus devices. What we are looking at is Android 4.2.2 with build number JDQ39.
Specifically this includes the Nexus 10 and Nexus 7 tablets as well as the Nexus 4, Galaxy Nexus (GSM/HSPA+) and Galaxy Nexus (Verizon Wireless) smartphone. Still missing however are some of the older devices including the Nexus S and Nexus S 4G smartphones along with the Motorola Xoom tablet.
The details of this update were posted by Jean-Baptiste Queru and interestingly enough, this marks the "first time that any device has all its binaries available for AOSP." This is in regards to this AOSP release including the full set of proprietary binaries for all variants of the Nexus 7 as well as the Nexus 4.
Otherwise, many of the older binaries remain available. Also worth noting, Queru has said that they also tweaked the Froyo, Gingerbread and ICS-mr1 branches so they can now be compiled on Ubuntu 12.04. Bottom line here, if you have been looking for any Nexus related binaries - follow the link at the bottom of this post.
