Thanks for this! But, the naming of the artifacts is different than it was, and is a bit confusing - it's not so clear which are master and which are 4.4.3 builds. For instance, for x86_64, I see these:

It looks like the last commit message - or maybe it's the last PR title - is in the name, instead of a branch name. In this case, I can guess the one where the message was "port_4.4.3_fix" is from 4.4.3 branch, but that won't necessarily always be so obvious.

Oh, those builds should not have been uploaded at all, since I manually ran them with "Publish to FTP: off". How annoying. Anyway, tomorrow there will be normal nightly builds again, but we'll have to delete these bad ones manually.
