Apple has been releasing new beta builds of the iPhone and iPad operating systems regularly since March. On Monday, Apple released the fourth beta for iOS 10.3.2 to registered developers, a week after rolling out the third one and a month after the release of iOS 10.3, which focused on security improvements and included new features such as Find My AirPods and a new Apple file system, among many others.

The fourth beta version is said to primarily focus on fixing bugs and enhancing the software. According to technology news site Redmond Pie, the improvements that came with the update include fixes for SiriKit car commands, Siri text responses, and third-party VPN apps. However, these updates specified on the release notes are apparently just similar to the fixes made in beta 2 and beta 3, which could disappoint those who have been expecting big changes with the new release. For those who are on the public beta program, the new update may be released within a couple of days.

The fourth beta for iOS 10.3.2 can be downloaded over the air or through Apple's Developer Center. Apple has yet to announce when the official software will arrive for all compatible devices.

In other news, apart from the iOS 10.3.2 beta 4 release, Apple has also released new beta updates for tvOS and watchOS. However, the update process for these is a bit more complex, according to Apple Insider. For the tvOS 10.2 beta testing, developers must have an Apple TV connected to a computer with iTunes, using a USB-C cable. On the other hand, the watchOS 3.2 beta testing involves using the iOS Watch app while charging the Apple Watch with at least 50 percent power. These also have not been distributed for public beta programs.
