 #### Bug Fix
 - Fixed an issue where Materialize Views would break with a custom schema.  Thanks to [Rory Sawyer](https://github.com/SoryRawyer)
 for the PR!
-- A few tests with LIMIT clause were broken due to parsing error when having settings in the query ([issue](https://github.com/ClickHouse/dbt-clickhouse/issues/223)). We added a dedicated limit placer, that takes into account the settings section (using a comment flag `-- settings_section` within the query).
