Looking for a parsec maintainer to assist with GHC 9.14 compatibility (is this package still actively maintained?)

Even though the parsec-3.1.18.0 boot package bundled with GHC 9.14.1 was itself compiled against base-4.22.0.0, the version on Hackage (with an outdated upper bound on base) seems to cause dependency resolution failures for packages that transitively depend on parsec-3.1.18.0 when building with GHC 9.14.1.

This looks like an error in the GHC release process.

GHC mirror of the parsec package

@wz1000 bumped this in the GHC submodules.

I don’t know if there was any communication with the parsec maintainers, but GHC shipping with unreleased boot libs has been a recurring issue.
