 # Changes
 
 * 2.6.next in progress
-  * Fix [#528](https://github.com/seancorfield/honeysql/issues/528) by preventing the `?` -> `??` escaping in SQL keywords just for operators.
   * Address [#527](https://github.com/seancorfield/honeysql/issues/527) by adding tests and more documentation for `:composite`.
   * Update Clojure versions (to 1.11.2 and 1.12.0-alpha9).
