[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)
