Version 4.3.2

Released on 2020-11-25.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 4.3.2.

We recommend that you upgrade to the latest 4.2 release before moving to 4.3.2.

A rolling upgrade from 4.2.6+ to 4.3.2 is supported.

Before upgrading, you should back up your data.

Fixes

• Fixed an issue that could cause browsers to prompt for a client certificate if SSL is enabled on the server side, even if no cert authentication method is configured.
• Fixed a regression introduced in CrateDB 4.1 resulting in duplicated recovery file chunk responses sent. This causes log entries of Transport handler not found ....
• Fixed an issue that resulted in records in pg_catalog.pg_proc which wouldn’t be joined with pg_catalog.pg_type. Clients like npgsql use this information and without it, the users received an error like The CLR array type System.Int32[] isn't supported by Npgsql or your PostgreSQL if using array types.
• Fixed an issue that could lead to stuck INSERT INTO .. RETURNING queries.
• Fixed a regression introduced in CrateDB >= 4.3 which prevents using regexp_matches() wrapped inside a subscript expression from being used as a GROUP BY expression.

This fixed the broken AdminUI->Montoring tab as it uses such a statement. - Fixed validation of GROUP BY expressions if an alias is used. The validation was by passed and resulted in an execution exception instead of an user friendly validation exception. - Fixed an issue that caused IS NULL and IS NOT NULL operators on columns of type OBJECT with the column policy IGNORED to match incorrect records. - Fixed an issue that led to an error like UnsupportedOperationException: Can't handle Symbol [ParameterSymbol: $1] if using INSERT INTO with a query that contains parameter place holders and a LIMIT clause. - Fixed an issue that led to an error when nesting multiple table functions.
