 * 1.2.next in progress
   * Fix #194 by throwing an exception if a table or column name used with the friendly SQL functions (or the SQL builder functions behind them) contains a "suspicious" character (currently, that's just `;`).
   * Update several test dependencies (incl. log4j2).
-  * Update `build-clj` to v0.6.1.
+  * Update `build-clj` to v0.6.3.
 
 * 1.2.753 -- 2021-11-17
   * Address #187 by adding `clj-kondo.exports` for future expansion (`with-transaction` is already built into `clj-kondo`).
