* Improve performance of `clickhouse-client` in interactive mode when Pretty formats are used. In previous versions, significant amount of time can be spent calculating visible width of UTF-8 string. This closes [#11323](https://github.com/ClickHouse/ClickHouse/issues/11323). [#11323](https://github.com/ClickHouse/ClickHouse/pull/11323) ([alexey-milovidov](https://github.com/alexey-milovidov)).

* Make queries with `sum` aggregate function and without GROUP BY keys to run multiple times faster. [#10992](https://github.com/ClickHouse/ClickHouse/pull/10992) ([alexey-milovidov](https://github.com/alexey-milovidov)).
