CHANGELOG.md

@@ -27,6 +27,7 @@ The supported method of passing ClickHouse server settings is to prefix such arg
 - Fixed issue with JSON key dot escaping. Closes [#571](https://github.com/ClickHouse/clickhouse-connect/issues/571)
 
 ### Improvements
+- Added Python 3.14 and PyPy 3.11 build support
 - Added `utc_tz_aware` parameter to client and query methods to opt in to returning timezone-aware UTC objects for DateTime/DateTime64 columns. Default behavior remains the same and returns tz naive objects for backward compatibility. Note: this parameter will likely be removed and only return tz-aware dts in some future release. Closes [#566](https://github.com/ClickHouse/clickhouse-connect/issues/566)
