MD5 Stuff - Executable Release
Some Release-build .exes for the MD5 sample implementations. These are Windows-only and I've only tested them on a single Windows 10 PC, so your mileage may very much vary, but if you're interested, and if they run for you, then you can use them to look at the MD5s from the new Quake reissue.
No support.
This is a techdemo/sample implementation, not a robust production-quality engine release. If it crashes for you, and if you're not prepared or able to roll up your own sleeves and get your own hands dirty with it, then you're probably better off waiting on one of the main Quake source ports to integrate MD5 support.
No Linux builds.
Same reason as "no support", I guess. If you're a Linux user, you might be able to use this code to help you integrate support to a Linux port, but you'd need to do this yourself.
