This list provides an overview of all changes in version 7.1.7. Version 7.1.7 was released on 2022-03-16.
Changed behavior
| Changelog entry | Changed behavior |
|---|---|
| 14476 | Updated pandas from 0.22 to 1.1.5 |
| 14096 | The Exasol ADO.NET and ODBC driver will not set snapshot transactions by default to "OFF" at connect time. |
| 13863 | ODBC: Truncation of string values follows ODBC standards (SQLGetData, SQLFetch or SQLFetchScroll) |
| 12960 | The HASHTYPE is extended to allow zero hash values (e.g. ‘0000-0000’). During the update to this database version all HASHTYPE columns will be migrated to the new storage format. This migration may take a while, depending on the number of HASHTYPE values. The new format requires an extra byte per row, so will use more memory. |
