Change Log
The Change Log lists all the updates, additions, fixes and other changes that have happened to MailScanner.
Complete Source
MailScanner on Github contains the complete source for the entire package including package build scripts.
Each of the packages above is a compressed tar file. Download it, unpack it and run the script in it. Warning: Not using the install script will more than likely leave you with an incomplete or broken installation.
Special note for ClamAV on RHEL/CentOS 7
ClamAV 0.100-1 introduced some breaking changes to its own package.  Here’s a little how-to to fix those issues after updating if affected as a courtesy.  New installs are not affected.
Remove/Backup old configs and service entries:

mv /etc/clamd.d/clamd.conf ~/clamd.conf.bak
mv /etc/tmpfiles.d/clamd.conf ~/clamd.conf.tmpfiles.bak
mv /etc/tmpfiles.d/clamd.scan.conf ~/clamd.scan.conf.bak
systemctl disable clam.freshclam.service
mv /usr/lib/systemd/system/clam.freshclam.service ~/clam.freshclam.service.bak
systemctl disable clam.scan.service
mv /usr/lib/systemd/system/clam.scan.service ~/clam.scan.service.bak
