Some mimetypes entries are out of date #141018
Description
Feature or enhancement
The reason why .exe & co are mapped to octect-stream is likely for convenience (the IANA type for .exe is https://www.iana.org/assignments/media-types/application/vnd.microsoft.portable-executable)
That seems like a bug, the addition of
.exe(1997) predates the official registration (2015) of theapplication/vnd.microsoft.portable-executablemimetype.
