On use of the 1st PowerCLI cmdlet, it would be nice if users are reminded that they might be running an old(er) PowerCLI version.
With on average 2 releases/year (and increasing) it might be handy to give a warning when the user's version is older than 1 year.
A link to the compatibility matrix and/or latest Release Notes and/or PowerCLI Changes document in the warning messages might be useful.
