- iOS-OTA-Downgrader will now be able to flash the latest baseband even if the jailbreak option is enabled - idevicerestore is now removed, futurerestore will now always be used - windows support is now removed (now in the "windows" branch and will no longer be updated or supported) - custom ipsw option is now removed - existing custom ipsw's created from previous commits will need to be deleted and re-created to use starting from this commit - custom ipsw's created in the windows version will NOT be compatible with the latest linux/macos versions of ota downgrader
