Don't Install iPadOS 13.4 If You're Jailbroken
If your tablet is currently jailbroken or you think you might want to jailbreak it in the future, you should probably avoid iPadOS 13.4 for now.
Jailbreak developers have released a tool for newer version of iOS 13 and iPadOS 13 though it's not compatible with iPad Air 2, iPad 5th Gen, or iPad Pro 1st Gen.
If you own one of those devices you'll need to stay put on older software for now.
You can follow the latest jailbreak developments right here. We should see some additional news emerge in the weeks ahead.
