Microsoft has released additional quarterly updates for Lync – these updates are focused on all Lync Server versions and include Lync 2013 mobile and LPE which apply to both Lync 2010 and Lync 2013. Currently there are no known new issues with any of the updates (more below), and the Lync 2013 Mobile clients have received significant feature updates. Personally I use 90% of the time the Windows Phone app and stability and meeting join times have been better and more responsive.
The Lync 2013 client has been updated to a new release version, and while that may sound like a great thing unfortunately the presence issue discussed previouslySeptember 2013 Microsoft Lync Update Presence Gotcha and in KB2883716 is still present. For those that wish to go down the patch of installing the update in my experience it is a one-way street. While it can be “uninstalled” in reality it breaks Lync beyond repair if you do so. Uninstalling Office and re-installing/patching is your worst-case scenario; using a restore point is your best case.
Database updates are not part of this upgrade cycle for Lync. To make sure you have the latest and greatest versions (you can always run the Install-CsDatabase cmdlet and if nothing needs to be done nothing changes) use the Test-CsDatabase cmdlet. Doug Deitterick has a nice blog listing the versions and steps so I will not reiterate them here.
