Metabase 0.49.14+ only.
Bug fixes
- Fixed the issue where the Metabase instance could end up broken if the ClickHouse instance was stopped during the upgrade to 1.5.0. (#242)
- Fixed variables substitution with Nullable Date, Date32, DateTime, and DateTime64 columns, where the generated query could fail with NULL values in the database due to an incorrect cast call. (#243)
