Hello, Can somebody explain how to resolve a problem with the resolver, specifically, my package (mathlist) appears on the Stackage page, but with the message "This package is not in any snapshots." I tried resolver: lts-20.21 (in stack.yaml), then changed this to resolver: ghc-9.4.5, but this doesn't make any difference. The page recommends adding the package to Stackage Nightly, and I guess I could try the third option, resolver: nightly-2023-05-19, but this seems odd. Why would I release a package with a particular hard-coded date for nightly? Shouldn't it just be "nightly" or something like this? Thanks, Dominick
