Yesterday, Apple has released iOs 8.3 (beta 4, build reference '12F5061'), the fourth for developers and second for public testers.
This beta is now out for both testers after Apple seeded the third iOS 8.3 beta two weeks ago and more than a month and a half after the first iOS 8.3 beta, Mac Rumors reported.
According to GSM Arena., the file size may vary, but it would certainly be above 100MB as it was shown on a screen captured photo released from Apple.
As for the iOs 8.3 beta 4 for developers, the "beta" tag from iCloud Photo Library has been removed, while the message filtering feature has been improved adding a new category "Unknown Senders" on the iMessages sent by people who aren't registered in users' contacts.
9to5Mac added that the CarPlay settings menu has disappeared in beta 4, though the Apple iOS 8.3 is expected to bring wireless support for CarPlay.
The beta also brings the new Apple Watch app that arrived with iOS 8.2, better support for two-form authentication for Google apps like Gmail, upgraded keyboard for changes in Emoji, links to the Mayo Clinic in the Health app and Apple Pay support for China on the UnionPay network, Gotta Be Mobile. reported.
"Other iOS 8.3 features include new language support for Siri including support for Danish, Dutch, Portuguese, Russian, Swedish, Thai, Turkish, and English for Indian users. It should should also bring some improvements to Siri's voice and a new Hey Siri feature that allows users to easily switch to speakerphone. It's shaping up to a large update and with a beta 4 now out, iPhone and iPad users should start keeping tabs on its progress," Gotta Be Mobile continued.
Apple has not revealed the iOs 8.3 release date, but BGR assumed that it might roll out within the next two months since Apple is set to introduce iOS 9 update at WWDC 2015 in June.
