 ### Added
 - _Nothing yet._
 
+## [0.6.0] - 2025-10-06
+
+### Added
+- Enabled the derive and template parser to understand the new formatter
+  specifier, keeping runtime rendering and compile-time diagnostics aligned with
+  `thiserror` while exposing the helper through `TemplateFormatterKind`.
+
+### Tests
+- Expanded the runtime formatter assertions and `trybuild` fixtures to cover the
+  new formatter branch, guarding both successful usage and descriptive error
+  messages.
+
+### Documentation
+- Documented the formatter addition across README variants and crate docs,
+  including updates to the formatter reference table and usage guidance.
