# Changelog

## v0.2.0

- Automatic literal type coercion in comparisons. When a literal is compared
  against a typed field (e.g., `performed_on >= "2026-05-20"` where
  `performed_on` is a `:date`), the literal is now wrapped with `type/2` so
  Ecto and the database driver cast it to the column's type. Previously this
  could fail in PostgreSQL with errors like `operator does not exist: date >= text`.
- Coercion sources its type information from the schema (`__schema__(:type, _)`),
  from the keyword form of `:allowed_fields`, and by walking association paths
  to the leaf field. Works for `==`, `!=`, `>=`, `<=`, and `includes` in both
  operand orders.
- Coercion is skipped when the literal's natural type already matches the field
  (e.g., string-vs-string, integer-vs-integer), so existing queries are not
  affected.
