Rocky Linux is here and more importantly, Rocky Linux 8.4 is just released.  According the Rocky Linux forums, this may be another release candidate as this was posted on May 28, 2021, “.he plan now is to get a 8.4 RC out there and then push that to a GA release. We learned a lot from our 8.3 RC, and we’re excited to apply that to 8.4.”

After downloading it, the first attempt to install failed with this message. ERROR Verification failed: (0x1A) Security Violation.  Pressing OK didn’t do any good.  It turned out to be the Boot Option of EFI.

After changing to BIOS, all went well. Note that the PRE-RELEASE TESTING is removed from the screen as seen here.  Could this be a release?

At first boot. No mention of PRE-PRODUCTION.
