+- Fixed `optionsList()` to preserve an explicitly empty string `title` on `oneOf`/`anyOf` options instead of falling back to the option's value, fixing [#4448](https://github.com/rjsf-team/react-jsonschema-form/issues/4448)
 - Updated `types.ts` to add `CyclicSchemaExpandProps` type and `CyclicSchemaExpandTemplate` in the `TemplatesType`
 - Updated `resolveAllReferences()` to add a new `markCycleOnDetection` prop which adds `RJSF_REF_CYCLE_KEY` marker (from `constants.ts`) to a schema that has been detected to have a cycle, partially fixing [#3907](https://github.com/rjsf-team/react-jsonschema-form/issues/3907)
 - Updated `hashForSchema()` to filter keys to remove `RJSF_REF_KEY` prefixed keys before hashing the schema
