Today, Apple has seen fit to release iOS 14.5, iPadOS 14.5, tvOS 14.5, and watchOS 7.4 to developers for testing purposes. If you're a developer, you can download the latest beta builds from Apple's Developer website right now. The new beta builds arrive a week after Apple publicly released iOS 14.4, iPadOS 14.4, tvOS 14.4, and watchOS 7.3. The update is sure to feature bug fixes and performance enhancements. Let's dive in to see what else has Apple added to the mix of updates.

Starting with iOS 14.5 and iPadOS 14.5 beta 1, you can download the build through the Apple Developer Center or via an over-the-air mechanism. Take note that you require an appropriate configuration profile from the Developer Center in order to install the latest beta. In terms of features, iOS 14.5 will bring forth Apple's App Tracking Transparency privacy feature. This will require the developers to ask for user consent via permission in order to access their random advertising identifier or IDFA that allows them to track user activity across apps and websites. While this is a major addition, there's no word as of now that details what else has Apple added in beta 1 of iOS 14.5.
