Apple released the fourth beta version of iOS 8.3, and since then we have been observing what has changed from the previous test compilation.
From "visible", we have this here:
In iOS 8.3 beta 3, we say that the Messages app (Messages) won a new option “Filtered” which separates people who are not on your contact list. Well, in beta 4 Apple changed the term to “Unknown” which makes a lot more sense.
On the Emojis keyboard (we highlight new features in iOS 8.3 beta 2), Apple improved the organization of the images, set the screen of recent items as standard and made changes in the new yellow characters giving them also yellow / golden hair.
Finally, in this compilation, Apple removed the “beta” stamp from the iCloud Photo Library (iCloud Photo Library), separated Apple Pay cards from regular tickets inside Passbook and temporarily disabled, of course wireless support for CarPlay.
Overall, the comments on iOS 8.3 that it is already getting pretty round and fast approaching getting ready for the big audience. But don't be hopeful that this will happen so soon; considering the addition of support for several new languages on Siri (including our Portuguese), it may be that this version is still in testing for at least another 1-2 months.
