    Feel like a dummy for asking, but I havent found an answer yet. When looking to download the latest JUNOS for any EX or SRX device, for example say for a EX4300, 
    they list it like this  , EX4300 Latest 20.4R3-Sx/21.2R3-Sx 2 Jun 2022. 

    Is it an either or pick, 20.4R3-Sx or 21.2R3-Sx, or any version in between that will fill the recommended need?  Sorry if I missed the explaination somewhere on the Support site.

    Yes, use the S2 version in the main Junos chain that you have deployed for the features.  Both 20.4 and 21.2 are recommended at that specific patch level.
