Leapwork Go 2026.12 introduces a more unified authentication model across multiple request protocols, including new support for WebSocket and Server-Sent Events (SSE). This release also enhances the authoring experience with integrated contextual help for scripts and protects the integrity of preview runs by preventing conflicting edits during execution. Together with improved regional job reliability and reporting accuracy, these updates provide a more stable and efficient environment for performance and API testing.
What’s new
Unified Auth Script header replacement
Auth Scripts can now return host-specific header values that automatically replace matching request headers before a connection starts. This functionality has been extended to support HTTP, WebSocket, and Server-Sent Events (SSE) requests, ensuring that each endpoint receives the correct authentication values without requiring manual header updates across different protocols.
Contextual help for Script and Auth Script
A new side-panel help experience is now available directly within the Script and Auth Script data item editors. This integrated documentation covers supported methods, placeholders, return values, and important execution limits, allowing users to understand and author complex scripts without leaving their current workflow.
Preview run edit protection
To ensure the stability of execution results and prevent state conflicts, sequence and step editing is now automatically disabled while a preview run is in progress. Editing controls are restored once the preview completes or is stopped, making the preview behavior clearer and more predictable.
What’s updated
Reporting and statistics consistency
Scheduled run result metrics have been synchronized to ensure that statistics displayed in the UI summary match those sent in notification emails. Additionally, the calculation of average bandwidth in PDF and HTML reports has been refined to accurately reflect the measurement intervals used during execution.
Bugs and Improvements
This release includes the following fixes to improve stability and reliability:
-
Preview Run Stability: Resolved issues where preview runs would reset prematurely when users interacted with response headers or changed request body types.
-
Reset Action Timing: Fixed a bug where the Reset action appeared prematurely while a preview run was still initializing.
-
Multi-tab Asset Management: Restored soft-deleted assets now open correctly even when multiple browser tabs are active, preventing workspace conflicts.
-
Dictionary Cache Handling: Addressed an issue where deleted parameterized dictionaries could return stale cached values from Redis.
-
Auth Script Documentation: Added the
awaitkeyword to all async methods in the Auth Script help content to ensure code snippets are accurate and functional.
