Yes, in this case, it’s NOS v7.4.1 release since it’s End of Version Maintenance (EOVM) date is May 2023.
Please see the Software Lifecycle Policy document for additional reference.
Since you are on 7.2.0c, if you upgrade to 7.2.0e which will be less disruptive, but it will only be patched till Feb 2021.
Lastly, if you plan to upgrade to 7.4.1 and have 40G optics, I would recommend waiting till 7.4.1a is release first due to the below Field Notice.
