We did remove the golden label from the GUI to avoid confusion with later versions that are subsequently named golden. Golden refers to the latest recommended version available at the time, which should be the most stable and up to date veresion. Feature releases alternatively offer some features that the golden may not, but it wouldn't be as stable so it isn't recommended unless you're looking for a particular new feature. You can always check what the latest recommendations are here (https://thehivecommunity.aerohive.com/s/question/0D50c00005jmpq9CAA/aerohive-hiveos-access-point-matrix), this page is updated every time we release a new version.
