Apple has released the public beta of iOS 16.6, ahead of the upcoming WWDC where iOS 17 is expected to debut. While the update doesn't introduce major new features, it includes a subtle change: users will now see an alert if they've blocked too many contacts, suggesting a system-imposed limit on the blocking function. This feature is designed to combat spam and unwanted messages, but may affect users who aggressively block numbers.

Alongside this change, the update likely includes routine bug fixes and performance improvements, consistent with Apple's typical pre-release cycle. The beta is available for iPhone, iPad, Mac, Apple Watch, and Apple TV through Apple’s public beta program. Users are advised to install beta software only on secondary devices and to back up data first.

The previous iOS 16.5 update brought end-to-end encrypted RCS messaging for cross-platform texting with Android users, as well as ads in the Maps app—changes that drew mixed reactions. The 16.6 beta continues Apple’s pattern of incremental refinements in the months leading up to a major OS launch.
