July's security updates went live a couple of days ago for all of the currently supported Nexus devices. The Pixel C is still unaccounted for, but it's not that unusual for it to lag a few days behind. There were some late-breaking updates for hardware drivers this month, which may also contribute to some delay on the Pixel C. In the meantime, there are plenty of changes to check out this month.

There are eight separate changelogs this month, but some of these are empty, created for Google's internal use. I've marked the ones that simply change a build number. As usual, Google's security bulletin contains explanations for most of the changes, but there are probably a couple of subtle bug fixes too.

  All of the changelogs have been posted

If you're curious about what has changed in the latest round of factory images for the Nexus family, there aren't many better ways to see the bare details than to browse through the changes exactly as they are written in the Android Open Source Project. We've generated changelogs from the available code commits from the latest round of updates. So far, this only includes the MOB30G-MOB30J builds, but the rest should be coming soon.

May's changelogs are pretty brief, owing basically all of their contents to the security-related fixes. In fact, of the currently available changelogs, it's only r40 (MOB30G) that contains anything of substance.
