 * Настройка `enable_optimize_predicate_expression` выключена по-умолчанию.
+
+### Улучшения:
+* Файлы *-preprocessed.xml записываются в директорию с данными (/var/lib/clickhouse/preprocessed_configs). Для /etc/clickhouse-server больше не нужен +w для пользователя clickhouse. Для удобства создан симлинк /var/lib/clickhouse/preprocessed_configs -> /etc/clickhouse-server/preprocessed
