1.9 release notes

Before attempting to upgrade to Document Engine 1.9, first upgrade to Document Engine 1.8 if you haven’t already, and make sure your application still runs as expected. Refer to our upgrade guide for more information.

Highlights

GdPicture update

This version ships with GdPicture 14.3.7. This is an upgrade that mainly brings fixes and rendering improvements to Microsoft Office documents.

Document listing

A new document listing endpoint has been added to the Document Engine API.

The document listing API allows you to query and retrieve a list of documents in your Document Engine instance. You can filter documents by metadata such as creation date and document title. This endpoint makes it easier to build document management interfaces, implement search functionality, and integrate with the new bulk deletion feature for comprehensive document management.

See the list documents with pagination guide for more information.

Bulk document deletion

This version introduces support for bulk document deletion.

Document Engine’s bulk deletion API enhances its document management capabilities by allowing you to delete multiple documents at once. You can specify multiple document IDs or filter by creation date range or title in a single request. This streamlines cleanup operations and archiving workflows, significantly improving efficiency for document management tasks.

OCR extensions

OCR capabilities in Document Engine have been revamped in this version.

  • The OCR engine now ships with support for more than 100 new languages (three-letter ISO 639-2 codes; see the Document Engine API for the full list of supported languages).
  • It’s now possible to specify multiple languages for OCR operations to improve accuracy for documents with mixed languages.

See the OCR server supported languages guide for more information.

Support for comments in Instant JSON

Instant JSON serialization format now supports comments for both import and export.

Breaking changes

LibreOffice conversion engine

The LibreOffice document conversion engine was deprecated in previous versions and is no longer available in Document Engine starting from version 1.9.0.

Upstream API

Use of JWT tokens in the upstream API is no longer possible. We have to rethink this part before reintroducing it.

Database migrations

This release doesn’t include any database migration.
