 ## [Unreleased]
 
+## [0.24.14] - 2025-10-30
+
+### Fixed
+- Declared a dedicated `benchmarks` Cargo feature and disabled the default
+  library benchmark harness so automation can enable Criterion with custom CLI
+  flags, restoring support for `--save-baseline` and other passthrough options
+  in CI.
+- Documented the required feature flag in the README and template to keep local
+  runs aligned with the CI workflow.
