According to tradition, a few hours after the release of the development version of the new system, the public iOS 13.5.5 / iPadOS 13.5.5 beta was also released to users.
When it comes to changes in the new version of the software for Apple mobile devices, unfortunately there are not many of them. The latest software focuses only on bug fixes, and in particular on blocking Jailbreak, which, as we know, could be done on almost all devices. You can learn more about Jailbreak iOS 11 – iOS 13.5 here. Participation in public tests is possible for free.
To sign up for beta testing of the new iOS you must go to the website beta.apple.com. As for the changes in this version of the system, you will find them here.
