# Version 3.5.21

### Bug Fixes

- Removed Windows credentials option from Microsoft SQL Server and MySQL Datasources (which was erroneously shown in UI).
- Fixed Sharepoint upload error (Error 12030 calling WINHTTP_CALLBACK_STATUS_REQUEST_ERROR).

### Improvements

- Access token for Sharepoint Upload Action is now automatically refreshed (should no longer be necessary to re-authenticate every e.g. 90 days).
- Added Save Content To Download Cache Action and Download API method.
- Added optimizations for data table extractions.
- Improved logging for CSRF token issues.
- Updated various libraries.

### Known Issues

- If upgrading to this version for a version below 3.5x, the Datasources that were defined to use Custom Windows Account are set to Service Account after the upgrade. Please set it back to Custom Windows Account manually.
- There is a timeout with the Vizlib Pivot Table as Chart element when using it together with Qlik Sense November 2023 Patch 2 and higher and having more than 10 Vizlib charts in the same report.
- Need to manually restart Mail & Deploy if you set a custom callback URL for the Azure AD User Directory.
- M&D doesn't support html code in the Vizlib Pivot and Vizlib Table headers. It does support html code in the data values.
- The filters are not enforced when using the action Activate Datasource Book, which apply filters, and Filter Datasource Field. To enforce the filters, use only the action Filter Datasource Field.
