Version 7.0.4 Release Notes
Please view the list below for an overview of all changes in version 7.0.4. Version 7.0.4 was released on 2020-11-26.
Changed Behavior
| Changelog Entry | Changed Behavior |
|---|---|
| 11058 | Exasol will send the CLOSE control frame after receiving the 'disconnect' command to initiate closing the WebSocket connection. |
| 10950 | If a custom TLS certificate was uploaded in ExaOperation, it will be used for WebSocket database connections instead of an autogenerated self-signed TLS-certificate. This does not affect ODBC, JDBC and ADO.NET, but only WebSocket API (e.g. via pyExasol). Also, if no custom certificate was uploaded, the default autogenerated TLS certificate for the database will be increased from 1024 to 2048 bits. See the issue description for more details. |
| 10899 | Filtering or joining a timestamp or date column with strings that contain invalid values now always throws an exception. |
| 10802 | LISTAGG and new FN_AGG_LISTAGG* capabilities were added to the virtual schema API. LISTAGG no longer uses the GROUP_CONCAT API. |
