Apple on Wednesday rolled out iOS 10.3.3 beta 6, an update that’s focused primarily on bug fixes and security enhancements. Both developers and public beta testers can grab the new update as an over-the-air download.

No significant changes have been discovered since Apple released the first beta for iOS 10.3.3. Something still may pop up in the final release, but it’s likely this newest update is meant to optimize the iOS experience.

With iOS 11 on the horizon, the release of iOS 10.3.3 is likely the last release of the iOS 10 era. Apple is expected to launch iOS 11 this fall.

If you want to give iOS 11 a shot and you’re not a developer, Apple opened up a public beta. However, it’s worth noting that using beta software on your main device is not a great idea due to bugs and kinks that need to be ironed out.
