Release Notes 2.259.0 (08.07.2026)

This release introduces updates to the embedded Editor, flexible prefill URL options via the API, and several stability fixes across billing and logging workflows.

New Features and Improvements

• Prefilled Viewer URLs via POST Added support for retrieving a Document Viewer URL containing prefill data and reviewer personal data using a POST request.
• GitHub SDK Updates Updated official SDKs and API wrappers across GitHub repositories to align with recent v4 API extensions.
• Form-First Review Enforcement Enhanced the Document Viewer workflow to require users to fill out the data collection form completely before the signing step becomes available.
• Schema Compatibility Fixed Model Context Protocol (MCP) tool schemas by removing empty-string enum values that caused validation failures for specific API clients.
• Core Documentation Added comprehensive details regarding prefill fields to the Store Document API documentation.

Bug Fixes

• Webhook Versioning Fix Fixed an issue where the document webhook response URL returned the initial, unsigned document version instead of the newly updated version after a signing event.
• Subscription Plan Management Resolved policy errors that blocked users from switching from annual to monthly plans, or modifying subscription tiers if an underlying account status change was pending.
• Usage Logging Type Error Fixed a system exception in the background logging system where a null value passed to the usage event tracker caused a type error.
