Apple Seeds iOS 5.1 Beta To Developers

Apple has given developers a new version of iOS 5 to test out ahead of a release to the public. The new version, named 5.1 represents the first significant update to iOS 5 since its release in mid-October. A supplementary software update that went out earlier this month fixed a number of bugs and security holes, as well as promised to fix poor battery life experienced by some users.

Today BGR posted the full release notes of the software, which developers must sign a nondisclosure agreement to use. The notes do not suggest any major new features in the build, despite anticipation otherwise. A report from German Mac site Macerkopf.de earlier this month suggested that 5.1 would bring extra features to Siri in the form of hardware controls, letting users adjust things like Wi-Fi and Bluetooth radios through the iPhone 4S voice assistant. As with other pre-release versions of iOS, expect this one to get another beta or two ahead of a public release, though Apple has a history of releasing these minor updates in quick succession.

Last year’s iOS 4.1 update came in September and introduced HD video uploading over Wi-Fi, TV show rentals on iTunes, GameCenter, and the capability to shoot high dynamic range photos on the iPhone’s built-in camera application. That update also addressed a proximity sensor issue, and overall system speed issues for iPhone 3G users.
