I've posted an update to the Extreme Hardware/Software Compatibility and Recommendation Matrices, dated August 5, 2016. The document contains a new section with release recommendations for EOS-based systems (K-Series, S-Series, and 7100-Series). There are also updates for new optical devices that are supported with Extreme hardware.
Here's a link to the document:
