What are the Lyviss end of life dates

Lyviss ended support of the  FCSDK 3.3.X with the release of 3.4.x. 
Lyviss ended Support of the FAS 2.4.x and FAS 2.5.x in June 2023 

As always, there are significant new features, performance improvements, WebRTC standards updates, and enhancements between releases that require the customer to upgrade from one release to another. In turn, our customers tend to stay very current and this is recommended.

So the dates are:

Fusion Application server 2.4.X (EOS - 30/06/2023)

Fusion Application server 2.5.X (EOS - 30/06/2023)
