Apple has released the fourth beta build of its iOS 7 mobile platform for developers.
The update contains a number of bug fixes and feature integrations for the platform, which powers the company's iPhone and iPad devices. Early reports suggest that the update includes fixes for issues in the calendar, iCloud and Safari components for iOS 7 beta 4.
Apple has previously outlined a number of planned features for the platform, including a revamped interface, new search features and better automobile integration.
Designed to allow developers to test out their applications, Apple's beta version of the iOS platform is usually closed off to users who aren't members of the firm's developer programme.
The release, however, signals a step forward by Apple towards the expected general release of the iOS 7 platform, which is expected to arrive in the days immediately prior to the release of the new iPhone model.
While Apple has yet to provide any information on its next iPhone, reports from manufacturers suggest that the update will include hardware updates for the iPhone 5 and possibly the introduction of a lower-priced entry-level model.
The release also comes as Apple looks to recover its developer programme following a takedown due to a security breach. The company said that while no sensitive information was believed to have been breached, attackers may have been able to view basic information such as users' names and addresses.
According to Apple's Developer Center status page, a number of services including videos, technical support and developer forums remained offline at the time of publication.
