I'm thinking of moving my [EcoEvo package](https://github.com/cklausme/EcoEvo) to the [Wolfram Language Paclet Repository](https://resources.wolframcloud.com/PacletRepository). [This page](https://resources.wolframcloud.com/PacletRepository/guidelines) says that Mathematica v13.0 is required for development, but I'm interested in the minimum version for users.  What is the oldest version of Mathematica that WLPR supports for users?
