External Email - Use Caution

Hi, I have a question about the FreeSurfer 7.4.1 release. A couple weeks ago I added 7.4.1 along with its sha256 checksum to spack (which uses the centos7 binaries atm) after checking the md5 hash that is provided on the downloads page. The sha256 was independently confirmed by a spack maintainer so I believe that the checksums I had were correct at the time. This week, while trying to install 7.4.1 from spack, the sha256 checksum failed so I checked the md5sum against the one published in the downloads again and it matched. Has the tarball for 7.4.1 been switched intentionally without notice?
