eFa 4.0.3 is now available for both CentOS 7 and 8.
We would also like to thank everyone for their support and contributions to this project. 
Fail2Ban has been added as a default feature. Existing users can optionally enable via the CLI.
Backing up a CentOS 7 eFa and restoring on CentOS 8 is supported using the standard built-in restore utility.
