 ### Breaking Changes
 
+- [17881](https://github.com/apache/superset/pull/17881): Previously simple adhoc filter values on string columns were stripped of enclosing single and double quotes. To fully support literal quotes in filters, both single and double quotes will no longer be removed from filter values.
 - [17984](https://github.com/apache/superset/pull/17984): Default Flask SECRET_KEY has changed for security reasons. You should always override with your own secret. Set `PREVIOUS_SECRET_KEY` (ex: PREVIOUS_SECRET_KEY = "\2\1thisismyscretkey\1\2\\e\\y\\y\\h") with your previous key and use `superset re-encrypt-secrets` to rotate you current secrets
 - [17556](https://github.com/apache/superset/pull/17556): Bumps mysqlclient from v1 to v2
 - [15254](https://github.com/apache/superset/pull/15254): Previously `QUERY_COST_FORMATTERS_BY_ENGINE`, `SQL_VALIDATORS_BY_ENGINE` and `SCHEDULED_QUERIES` were expected to be defined in the feature flag dictionary in the `config.py` file. These should now be defined as a top-level config, with the feature flag dictionary being reserved for boolean only values.
