Microsoft has released CU April 2014 for Lync Edition Phones

New Lync Phone Edition (LPE) firmware has been released for all phones. Keeping the phones up-to-date with current firmware is imperative – too often I run into Lync certificate updates where the phones do not have a current root certificate for newly issued public certs and everything comes to a screeching halt. As a side, my basic work around for this is to setup an SE server with an internally accessible CA (read http is in the CRL and AIA), update it to the latest firmware, and then use on the phone on production. A pain, yes, but sometimes needed even if you are diligent as it is not uncommon to receive new phones with old firmware.

Microsoft has released a March 2014 update for Lync 2013 to address a memory leak

Microsoft has released an update for Lync 2013 that is focused on correcting a single issue – memory leaks during a video call on hardware that has an accelerated H.264 chipset KB2933495. The patch will be offered to all computers via Windows Update and if the situation never applies to you – oh well, just be content to know you are on the latest version of Lync post SP1. There have been issues reported regarding the Gallery View within Lync not working correctly since SP1, but this hotfix does not address that issue. There are two known issues – Persistent Chat file transfers may fail and screen readers may not be able to read the Lync keystrokes.

There are now 4 pre-requisites for the Lync patch which include MSO (KB2727096), MSORES (KB2817624), IDCRL (KB2817626), and Lynchelp (KB2817678).
