v0.2.0

Added

• source option for :union, :list, and :tuple types.
• validate functions can now return :ok, :error, or {:error, reason} in addition to true/false. {:error, reason} allows custom error reasons; :ok/:error mirror true/false.

Changed

• Dynamic maps (keys/values) now collect all entry errors instead of stopping at the first one, consistent with how fields behave.

Documentation

• New guide: using Mold with HTTP clients.
• New guide: formatting errors.
• Trace examples in README and parse!/2 docstring now use atoms instead of strings.
