Apple Lossless Audio CODEC (ALAC), you want all your users to be protected at all times in the face of any threat or vulnerability that may affect its ecosystem, be it mobile or desktop and is continually releasing updates, sometimes outside of its roadmap when serious security problems are detected.
To do this, every time you launch a new version of iOS, shortly after it stops signing the previous version, that is, we can no longer restore our device to a version that is no longer valid at that time if we are forced to restore our terminal. With the release of iOS 12.3, Apple has stopped signing iOS 12.2.
Apple launched just over a week ago, the final version of iOS 12.3, a version that after quit signing iOS 12.2 becomes the only version to which we can restore our device in case you have to, something that only happens if your terminal is presenting different problems of operation, battery consumption ...
The latest version of iOS and which is currently the only one available on Apple's servers, iOS 12.3, offers us as the main novelty Apple TV Channels, although it is only available in the United States, an application through which Apple wants to become a service broker that allows us to contract different streaming video services such as HBO, ShowTime, CBS ... and be able to enjoy its content without having to use its application.
Currently, Apple is working has already launched the second beta of iOS 12.4, version that is already in the hands of the developers. At the moment, it seems that no important news, something logical if we consider that the official presentation of iOS 13 is just around the corner, during the presentation event of the WWDC 2019, which will take place on June 3.
