Recently Apple released the Apple iOS 10.3 and Watch OS 3.2 to public.
Now the company is releasing new beta builds of iOS, TV OS and watch OS. The beta builds coming are of developer branch which is obvious. The company has now started rolling out first beta builds of iOS 10.3.2 , TV OS 10.2.1 and Watch OS 3.2.2 to developers. The update can be downloaded by registered developers from the Apple download centre or it can be downloaded via OTA also with proper configuration. The iOS 10.3.2 beta 1 has a size of 534MB and need to download over WiFi network.
The company hasn’t provided any detailed Changelog or release note about these updates. We can assume it to be just migration builds from previous public builds. Some major changes include security fixes and bug fixes throughout the system .
