Ever since the unc0ver jailbreak added support for iOS & iPadOS 14.0-14.3, the tool has received a steady stream of updates from lead developer Pwn20wnd with various bug fixes and performance improvements to improve the performance and stability of the jailbreak experience overall.
While unc0ver v6.1.0 was recently released to resolve all known issues with its iOS & iPadOS 14.0-14.3 support, it seems that more room for improvement was discovered following that release, as the tool was just updated again to version 6.1.1 this afternoon.
