Warnings:

• The 'description' field should be longer than the 'synopsis' field. It's useful to provide an informative 'description' to allow Haskell programmers who have never heard about your package to understand the purpose of your package. The 'description' field content is typically shown by tooling (e.g. 'cabal info', Haddock, Hackage) below the 'synopsis' which serves as a headline. Please refer to <https://cabal.readthedocs.io/en/stable/cabal-package.html#package-properties> for more details.
• 'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
• These packages miss upper bounds: - aeson - base16-bytestring - bytes - bytestring - containers - cryptonite - memory - scientific - strict - template-haskell - text - time - transformers - unordered-containers - vector - void Please add them, using `cabal gen-bounds` for suggestions.
