Apple has seeded the upcoming iOS 7.1 update to developers this week, which only has minor changes but has a number of known issues.
The first beta of iOS 7.1 is labelled as build number 11D5099e, and closely follows the public release of iOS 7.0.4.
In the release notes for the beta, Apple doesn't reveal any new features or significant changes, but there are reportedly a number of known issues. These issues include problems with Bluetooth, iTunes Match and developer tools.
It's likely, then, that Apple will seed more builds of the update to developers for testing, before the final version is released to the public.
In addition to the iOS 7.1 update, Apple has also released a new beta for Apple TV version 6.1.
