## Metabase 0.63.0

- `metabase.driver.sql-jdbc.execute/cancelation-poisons-connection?` `[driver]` -- whether canceling a `Statement`
leaves the `Connection` unfit for the next query, so that it must be discarded rather than returned to the
connection pool. The query processor cancels a `Statement` whenever reduction stops before the `ResultSet` runs out
of rows, which abandons a result set the server is still producing. Defaults to `false`, because most drivers
recover on their own; `:sqlserver` overrides it to `true`.

- `metabase.driver/validate-impersonated-query` `[driver query]` now has a `:sql-jdbc` implementation that
enforces, for every JDBC driver, that a connection-impersonated native query is a single statement.
