 # Changelog
 
+## [0.12.0] - 2026-05-28
+
+- ✨ Features
+
+  - Introduce the `Redactor` trait as the primary interface for redaction, replacing direct use of `RedactionEngine` in trait signatures.
+  - `RedactionEngine` now implements the `Redactor` trait.
+  - `RedactedDebug::fmt` and `RedactedDisplay::fmt` now accept `&dyn Redactor` instead of `&RedactionEngine`.
+  - `RedactedToString::to_redacted_string` now accepts `&dyn Redactor` instead of `&RedactionEngine`.
+  - Rename `would_redact` into `redacts` and implement it for all redactors.
+  - Move core types and traits (`Classified`, `DataClass`, `IntoDataClass`, `RedactedDebug`, `RedactedDisplay`, `RedactedToString`, `Redactor`) to the new `data_privacy_core` crate, re-exported from `data_privacy`.
+
