Apple has released iOS 6 beta 3, which includes some new Maps settings and Mail icons, among other things.

As noted by MacRumors, the release comes about three weeks after the last beta version. In the brief release notes, Apple said only that beta 3 includes "bug fixes and improvements," but MacRumors set up a thread to chart add-ons as they are discovered.

That thread revealed that iOS 6 beta 3 improvements include auto brightness that increases gradually instead of instantly and pictures next to privacy settings. There are also new Maps settings that allow for volume, distance, and label customisation, while the Mail app has new icons for junk, trash, and archive.

The iOS 6 beta 2 update did not appear to include any new features. When updating to the new version, however, the icon was animated with spinning gears.

Apple unveiled iOS 6 at its Worldwide Developer Conference (WWDC) in June. It will include a revamped Maps app, Siri on the iPad, as well as Facebook integration, and FaceTime video chat over cellular networks.

That revamped Maps app ditches Google Maps in favour of an in-house offering developed by Cupertino and using TomTom map data.

Apple's iOS 6 is expected in the autumn, likely with the release of the next-gen iPhone. The last version, iOS 5, came out in October alongside iCloud.
