This is a a small but important update; package details now show the minimum base requirement. Usually this is a version of SkySpark, and it quickly lets you know if the package is compatible with your system.
The same information is listed on a package's Versions page allowing users of older systems to quickly identify compatible packages.
If you're a SkySpark OEM and would like your product to be listed as a requirement for StackHub packages, then ping me an email! (See footer for address.)
Thanks go to BASSG and Anka Labs for the suggestion.
