## [0.9.0] - 2026-06-02

### Added
- `Errata.create/2` macro to create an error of any type while capturing the
  current env, without a separate `require` for each error module. (#4)
- `Errata.to_map/1` to convert any Errata error to a plain, JSON-encodable map
  without needing to know the error's specific module. (#5)
- `Errata.display_message/1` to retrieve the bare, human-readable `:message` of
  an error (without the `:reason` suffix that `Exception.message/1` appends),
  for rendering errors to end users. (#7)

### Changed
- **Breaking:** `new/1`, `create/1`, and `raise/2` now raise an `ArgumentError`
  when given unrecognized param keys instead of silently ignoring them. Only
  `:message`, `:reason`, and `:context` are accepted. Callers that previously
  relied on extra keys being dropped will need to remove them. (#3)

### Fixed
- Serialized error maps (`to_map/1`) and their JSON form no longer leak the
  `Elixir.` prefix on module names: `error_type` and `env.module` are now
  rendered as e.g. `"MyApp.Foo"` (as strings rather than raw atoms), and
  `env.file_line` no longer includes a trailing colon. (#6)
