UAT release	Production release
27 October 2025	10 November 2025

We've been hard at work this month making useful improvements! We have a new data retention feature that automatically removes older log data from Spark systems.

New: Data retention policies for API Call History and Event Log

At Coherent, your data matters to us and we want to give you more control over how it’s managed on our platform. Spark already lets you upload, download, and delete key data assets.

With this release, we’re introducing data retention settings for API Call History and Event Logs. We can now help you to configure how long these records are kept. After the retention period, entries will be automatically removed from Spark’s databases.

This helps your organization stay aligned with internal data policies and security requirements, while keeping your workspace clean and efficient.

Want to enable this feature for your Spark tenant? Just reach out to your Customer Success representative.

Notable enhancements

🧮 Testing Center

• Download testbed results faster with the new Excel (fast) download. This is a beta feature made available to all users that enables downloading large testbed results much faster.

• Improved terminology in the Testing Center to be more consistent across the user experience.

🐚 Spark Shell updates

• Spark Shell can be configured to display the call_id after a successful submission.

😎 User interface improvements

• Updated list view across the homepage, folder overview, and testbed screens to be more intuitive to use.

• Improved handling of downloaded documents. If the file was generated but you missed the download, the download can be accessed from the Background activity menu within 15 minutes without having to regenerate the entire file.

• Setting permissions should be much faster for folders with many services and/or users.

• The Service Documentation screens have some updates to improve usability.

🧠 Neuron and Xcall improvements

• Neuron compiler enhancements, updates and fixes across a number of Excel functions including better performance for Lambda functions.

• Improved handling of Xcall request meta fields.

• Services that use Xcall can now return the proper call_id reference from the downstream API call. This allows better management and fetching of data from downstream API calls.

• Xcall can now be debugged using the new API request parameter debug_xcall. When this is used, the API response will include a trace of the Xcalls made during the execution of the API call. Learn more in the API documentation.

📤 Transform updates

There is a change to the JSONtransforms which will return the Content-Type header properly as application/json rather than text/plain. This may potentially impact current integrations that check the Content-Type field.

• The newest version of the JSONata (2.1.0) package is available in JSONtransforms_v1.0.0 and Nodejs22_v1.0.0.
