What's new?
UAT release
Production release
July 27, 2026
August 10, 2026
We've got a helpful safeguard for you this month: Spark now checks for mapping changes when you upload an updated file, giving you an early heads-up before anything reaches your integrations.
And don't miss our latest customer spotlight and case study with Óptima Mayores, whose two-person IT team runs an entire business on Spark.
This release includes updates available in both UAT and Production.
Mapping differences highlighted on upload
When updating Spark services, Spark will inform you if the uploaded file includes new or removed mappings. This provides an additional check to the user to inform of any consequential changes to their Spark integrations and testing.
Spark will also suggest users to choose a major version update to indicate that there are incompatible API changes. This follows semantic versioning guidelines.
Notable Enhancements
Testing Center testbed results now include expanded tables for CSV downloads.
Coherent Assistant Testbed feature now supports running Xsolve to when making Excel-calculated testbed results. This enables verification between Excel and Spark results that include solve functions.
Service Documentation indicates last modified date including for any service versions that have been edited.
Please review the scheduled updates to the JSON and XML parsing packages. Updates to dependent packages make take place on short notice for any vulnerability fixes.
The commonly used JSONata package in the JSONtransforms will have a major update in the September release.
How a two-person IT team runs an entire business on Spark
Óptima Mayores serves customer projections, partner portals, and internal workflows from models deployed on Spark. Go-live took four days, reporting that used to eat a full day now takes five minutes, and every API call is traceable to the channel that made it.
