Apple today seeded the fifth beta of iOS 16.1 and the sixth beta of iPadOS 16.1 updates to developers. (The two betas are on different release schedules.)
The developer beta builds are available to developers through the Apple Developer Center or over the air on devices with the proper configuration installed.
Public builds of iOS 16.1 and iPadOS 16.1 can be downloaded via the Apple Beta Software Program website by users signed up to take part in the testing program. If you’re interested in trying out the betas of the upcoming operating systems you can sign up for the program by clicking the same link.
The iOS 16.1 beta 5 Release Notes are as follows:
Home
Known issues
- You might receive an alert to turn on Wi-Fi when pairing a Matter accessory. (98460235)
Workaround: Ensure your device is connected to your Wi-Fi network.
- Adjusting the color or color temperature might result in an unexpected color set on a Matter accessory. (98578966)
- Accessory details might not open if a Matter accessory is unreachable. (99232316)
- The device that initiates the pairing needs to use the same iCloud account as the home hub. Only the owner of a home, not an invited user, can pair Matter accessories. (76012945)
Memory Allocation
Known Issues
- The system memory allocator
freeoperation zeroes out all deallocated blocks in iOS 16.1 beta or later. Invalid accesses to free memory might result in new crashes or corruption, including:
- Read-after-free bugs that previously observed the old contents of a block may now observe zeroes instead
- Write-after-free bugs may now cause subsequent calls to
callocto return non-zero memoryTo debug these issues, use Address Sanitizer and Guard Malloc (see
libgmalloc(3)). (97449075)
As usual, MacTrast and Apple both warn users to not install any betas on their daily driver iPhone or iPad. Instead, only install betas on a device set aside for testing purposes.
