Version 3.5.21

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).

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.

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.
