In a blog post, Beom Soo Park, Skype's beta program manager, called the release "a hotfix for Skype 4.1." It features fixes for a series of issues in audio and video, which were widely reported by users accessing the service on iPhone 5 devices, or anything else running iOS 6.
Specifically, fixes were provided for a UI freezing problem that surfaced when placing audio and video calls in iPhone 5, and an intermittent audio and video calling issue on iOS 6.
"Thank you for all your valuable feedback which has enabled us to address the issues quickly," wrote Park. "We recommend that everyone upgrade to the newly released Skype for iPhone and Skype for iPad applications from the Apple App Store."
Other improvements have been made in addition to the patch. There is no longer a limit on the size of photos users want to send, loading times are quicker, the Bluetooth experience has been enhanced and the new service as a whole should consume less battery power than its predecessors.
Skype 4.1.1 is compatible with devices running iOS 4.3 and above.
Park concluded that any further advice from consumers would be greatly appreciated, and should be directed to the Skype Support Network.
