+## [3.0.1] - 2023-09-13
+
+### Added
+
+- In WordPressCS 3.0.0, the functionality of the `WordPress.Security.EscapeOutput` sniff was updated to report unescaped message parameters passed to exceptions created in `throw` statements. This specific violation now has a separate error code: `ExceptionNotEscaped`. This will allow users to ignore or exclude that specific error code. Props [@anomiex].
+    The error code(s) for other escaping issues flagged by the sniff remain unchanged.
+
+### Changed
+
+- Updated the CI workflow to test the example ruleset for issues.
+- Funding files and updates in the Readme about funding the project.
+
+### Fixed
+
+- Fixed a sniff name in the `phpcs.xml.dist.sample` file (case-sensitive sniff name). Props [@dawidurbanski].
