With the first release of an update for Skype for Business Server 2015, it is a good opportunity to publish a list of Cumulative Updates. We will try to keep it updated as soon as a new Cumulative Update is released.
Like in the previous versions, this list will include the version for the Core Components. This is because not all components are updated when we apply a Cumulative Update.
The previous lists for the Lync Server can be found in the following links:
Lync Server 2010 Cumulative Update List
Lync Server 2013 Cumulative Update List
We already made a post on how to check the component version using PowerShell:
