EPEL Playground was shut down in January 2022
EPEL 8 Playground was a place that developers and maintainers could "play
around" with updated, or changed packages in epel. EPEL Playground never
really worked out and ended up being more of a burden than helpful.
If developers or maintainers want something similar to EPEL Playground we
recommend Fedora COPR, which has availability for EPEL builds.
The epel8-playground dnf repo's are still on the mirrors so we don't break
machines that might have them enabled. They will eventually be archived
and removed. If you know of any machines that might still be getting
updates from epel8-playground, please disable the repo.
