I need to run the new security patches on Magento Open Source 2.4.3 - 2.4.3-p1 but Adobe don't actually elaborate on how to choose the correct version. My guess would be the COMPOSER version, but I would like to understand this, so could someone please explain how you know which one to use?

My open source instance was originally from an archive.
