[richardlau]

Serve .lib files with application/octet-stream content-type.

Was going to ask if the exe needed to be added, but looks like it's part of the default set https://github.com/nginx/nginx/blob/master/conf/mime.types

The only other one that might be missing is https://www.iana.org/assignments/media-types/text/tab-separated-values for the .tab files. Don't think that has any functional change like this change actually does

Forgot to mention that I have already deployed the change in this PR on our two servers.

I'm inclined for now to leave that unless someone runs into a problem with the .tab files.
