Haskell Packages
All these packages are tested to work on GHC 8.6.5–9.10.1 without generating any warnings, and some are still tested to work as far back as 8.0.2. I follow the PVP, so you can rely on that for setting upper bounds on compatible versions. Additionally, any changes in the fourth decimal place of the version numbers is just a packaging thing, no real effects on code.
