+# [4.12.0] - 2025-02-26
+
+### Changed
+* Gherkin::VERSION is deprecated and will not be updated, use the composer runtime API if you need to identify the
+  running version. This also changes the value used to namespace cached feature files.
+  by @acoulton in [#279](https://github.com/Behat/Gherkin/pull/279)
+
+### Added
+
+* Provide `CachedArrayKeywords::withDefaultKeywords()` to create an instance without an external dependency on the path
+  to the `i18n.php` file in this repo. **NOTE** that paths to source files will change in the next Gherkin release -
+  use the new constructor to avoid any impact.
