[0.2.0.0] — July 2025

• Breaking Changes:

  • Complete rewrite of the 'NeedsBuilder'
    • Please refer to the examples to see how to build packed data
  • Dropping support for GHC < 9.10.
    • 'NeedsBuilder' relies on linear types and type inference is broken before that version

• Features:

  • 'PackedReader' has been rewritten, however the API should be retro-compatible
  • The code generator defines pattern synonyms, allowing one to pattern-match on packed data using a native 'case' expression
    • Refer to the examples (e.g. Sum) to see how it works
    • The generated 'case' functions are still generated, but they use these pattern synonyms under the hood
