The new beta update comes exactly one week after the release of iOS 12.3 dev beta 3. 19659002] We will not know exactly what's in the last beta until we dive into both the beta and release notes. Apart from new features and striking changes, Beta 4 is likely to introduce bug fixes for issues that have occurred in the last three betas. Issues that Apple may not even highlight in the published release notes.
We will also highlight all the new features that Apple includes with this update. While 12.3 was not the most exciting iPhone OS overall, it did introduce us to Apple TV channels in addition to a handful of bug fixes for issues found during this beta cycle.
During the release of Beta 1
- iOS 12.3 Beta 3 can only be installed if you are running iOS 12.3 Beta 2. This issue will be resolved with the next beta release, so you can install it from other versions of iOS as well.
- The Accessibility Events switch has been removed because related aspects of W3C's AOM are no longer applicable. (49784417)
Date and time
- Support for the Reiwa (??) era of the Japanese calendar, which begins on May 1, 2019, is now available. The first year of the Japanese calendar era is called "??" shown. ("Gannen") instead of "1?", Except in the shorter formats in the numeric style, which usually also use the narrow time name; for example: "R1 / 05/01". (27323929)
- If you change the system time before May 1, unexpected behavior may occur when you use a device whose system language and calendar are set to Japanese. (49371044)
