In brief

Show & tell

  • explainable-predicates by Chris Smith

    The explainable-predicates package provides a Predicate a type, which is esssntially “a -> Bool that can explain itself.”

  • GHCup version 0.1.17 by Julian Ospald

  • merge, cropty, trust-chain by Samuel Schlesinger

    Figured I should post these new ones here, as they might actually be useful for someone else.

  • random version 1.2.1 by Alexey Kuleshevich

    First release since the rewrite a year ago. This release mostly takes care of some technical debt, performance regression on ghc-9, support for ghc-9.2 and other minor fixups.

  • Reactive Banana version by Ollie Charles

    Reactive Banana is a library for functional reactive programming. This release is mostly a maintenance one, though there a few new goodies.
