So I am deploying Cisco WSA 395 and SMA 395 and I wanted to know stable version for both of these appliance as I am looking to upgrade them first and then start to configure them.
I went on Cisco's download but there was no mark for recommended version.
you can check the compatibility matrix for WSA and SMA from here:
note that you should check the Configuration Master compatibility as well, which in the document you can find it as CM.
the GD versions are Gold deployment
the MD are maintenance deployment
also you can check the release notes before upgrading to see the known bugs and fixed bugs
