Microsoft has released an update for Lync 2013 yesterday that corrects multiple issues but most notably it improves sharing performance. The actual increases are still to be determined by myself, but I can also note conversation taskbar icons have changed as well. Before I recommend the latest patch I am going to run with it for a short while. J
One interesting note from the KB article is you may or may not see the correct version number post install. Why? Great question but the note states: “After you install this update, the Lync 2013 version may not be displayed correctly as15.0.4605.1003. Instead, it may be displayed as an earlier version, such as15.0.4605.1000.”
There are four pre-requisites for the Lync patch (this has not recently changed) which include MSO (KB2727096), MSORES (KB2817624), IDCRL (KB2817626), and Lynchelp (KB2817678).

It has been discovered that the latest Apple iOS upgrade 7.1 for iPhone, iTouch, and iPad devices breaks current Lync 2013 functionality. Specifically, it has been found that the update creates interoperability issues which causes voice and video to fail when using these devices. Microsoft is aware of the issue as seen in KB2955745 but there is currently no fix or workaround available.
The current solution? Hold off upgrading your Apple devices until a fix is found or you may be without Lync Audio/Video (I say might as Apple iPad Air and iPad Mini do not appear to exhibit the issue).
UPDATE
An update has been released and availabile in the iTunes store and may be foundhere. This update addresses the Apple flaw.
