One day after releasing the second beta of iOS 11, Apple on Thursday began rolling out the fourth beta for iOS 10.3.3.

As far as we know, the release is primarily focused on squashing bugs and enhancing the software—no major changes have been discovered since the first beta of iOS 10.3.3 was released. However, if you own a 12.9-inch iPad Pro, you will find new wallpapers.

As we power through summer and head toward the fall months, this will likely be Apple’s final consumer release before iOS 11 is officially released to consumers.

If anything significant pops up in the the latest beta for iOS 10.3.3, we’ll be sure to let you know.
