+# 1.50.0
+
+After Metabase 0.50.0, a new naming convention exists for the driver's releases. The new one is intended to reflect the Metabase version the driver is supposed to run on. For example, the driver version 1.50.0 means that it should be used with Metabase v0.50.x or Metabase EE 1.50.x _only_, and it is _not guaranteed_ that this particular version of the driver can work with the previous or the following versions of Metabase.
+
+### New features
+
+* Added Metabase 0.50.x support.
+
+### Improvements
+
+* Bumped the JDBC driver to [0.6.1](https://github.com/ClickHouse/clickhouse-java/releases/tag/v0.6.1).
+
+### Bug fixes
+
+* Fixed the issue where the connection impersonation feature support could be incorrectly reported as disabled.
+
+### Other
+
+* The new ClickHouse analyzer, [which is enabled by default in 24.3+](https://clickhouse.com/blog/clickhouse-release-24-03#analyzer-enabled-by-default), is disabled for the queries executed by the driver, as it shows some compatibilities with the queries generated by Metabase (see [this issue](https://github.com/ClickHouse/ClickHouse/issues/64487) for more details).
+* The `:window-functions/offset` Metabase feature is currently disabled, as the default implementation generates queries incompatible with ClickHouse. See [this issue](https://github.com/ClickHouse/metabase-clickhouse-driver/issues/245) for tracking.
