Although a large portion of the Nexus tablet line-up was only recently updated to Android 5.1.0 Lollipop, it looks like Google's software engineers are still hard at work providing software updates for Nexus tablets.
Based on Google's previous factory image release patterns, Nexus 7 versions with mobile data radios should also get the Android 5.1.1 factory images in the near future. We're also hearing reports that the Nexus 10 has started receiving the 5.1.1 OTA update, and it's very likely that Google will soon start rolling OTA updates for the other tablets mentioned above as well.
It's very interesting to see that Google is updating the Nexus 10, a tablet launched more than a couple of years ago, to Android 5.1.1 Lollipop, while the both the Wi-Fi only and the LTE versions of the Google Nexus 9, the most recent Nexus tablet, is still running Android 5.0.1 Lollipop.
