Release Notes
April 2026
We now allow you to update the primary key column after the initial sync when using the Upsert file using custom primary key option.
We have added a new toggle, Allow inconsistent row lengths, to the connection setup forms to support syncing rows in CSV files with inconsistent lengths for the following connectors:
- Amazon S3
- Azure Blob Storage
- Box
- Dropbox
- FTP
- Google Cloud Storage
- Google Drive
- SharePoint
- SFTP
- S3-Compatible Storage
This feature is available only to all new connections created after 13 April, 2026. We are gradually rolling out this feature to all existing connections. For more information, see our documentation.
