If you are part of Apple’s public beta then you should take note that there is a new version available.
The beta will include a number of features that were released in the fourth developer beta on August 1st, however, not all, given that this version is available to the public. Some of those new features include new emoji, new keyboard sounds and much more.
However, as Apple do not state what is included in the beta, we don’t know for sure.
If you are part of Apple’s Public Beta you can download the new version by tapping Settings > General > Software Update on iOS, or by heading to the update segment of the Mac App Store on MacOS.
You should note that beta releases are in no way stable, and you should not expect them to work efficiently, or even at all, so if you care about your main device, install it on another.
The final consumer version of MacOS Sierra is expected to be released later this year, and iOS 10 is expected for this autumn.
