The factory images are up–some of them–so it's time to take a peek under the covers to discover any changes made to the Android Open Source Project for April's security updates. To make this a bit easier, we've generated changelogs based on the commit history that was just posted to AOSP last night.

As you might expect, the majority of the changes are going to be related to the issues set forth in the April Security Bulletin. A few others appear to be relatively small bug fixes, but nothing jumps out at me as a change that will directly affect user experience or any particularly noticeable bugs.

February's batch of factory images started turning up earlier today and Google followed up with a push to AOSP a few hours later. As usual, we've got some changelogs to look over. The focus this month appears to be entirely on sealing any holes that could be used by bad people to do bad things.

Google posted a security bulletin with a list of fixes found in this release, and there are a few pretty big ones this month. Five items have been tagged Critical, including two that allowed for remote code execution without any user interaction, and the remaining three could have been used for privilege escalation.

The monthly security update for January is starting to roll out to Nexus devices. Factory images turned up yesterday morning and now we've got some changelogs from the Android Open Source Project (AOSP) if you're interested in taking a deeper look at exactly how things have been tweaked.

Unlike the 6.0.1 release in December, this month's adjustments appear to be entirely focused on security fixes. Google has a bulletin describing the relevant security issues addressed with this release. There are also a couple of builds specific to the Pixel C, including one that appears quite large. Like some of the previous changelogs, this is merely because it technically starts from a base version (i.e.

The factory images have landed and the OTAs are about to start rolling out shortly. As we already know, there are new emoji to fill out the Unicode 8.0 spec, band 12 support for T-Mobile, "until next alarm" for do not disturb mode, and a shortcut to launch the camera with a double-click of the power button. The December security updates are also an important part of the latest update. Of course, these aren't the only changes that take place, so we generate changelogs from the Android source code to find some of the other things going on with the OS.

Google's monthly security updates are out in the form of factory images, and that means it's time for some new code in AOSP. Since these versions are dedicated to closing security holes, there certainly won't be any new features and the bug fixes probably won't have much effect on battery life or performance, but they will keep the baddies from treating your phone like it runs an old version of Windows.

A number of serious vulnerabilities were fixed in this release, including two critical issues that could be used for remote code execution. Details have been posted on the Nexus Security Bulletin.
