If you've been comparing testbed results, the whole experience just got faster and more customizable — including a new Excel fast export (beta) that handles larger outputs without the wait. ## Updates to testing center comparisons
Our Testing Center enables the application of models against large datasets for testing and modeling purposes. With multiple testbed results, users can compare results to better understand changes in model outputs. We've added new capabilities to testbed comparisons to make it faster and easier to customize the comparison output. * New *Excel fast* (beta) option that writes out larger outputs faster than the *classic Excel* option. * Ability to retain only mismatches in the comparison to more quickly produce a report checking if two results are exactly the same. * Skip downloading of inputs to reduce the size of the report. * Customize the number of records and heading order. ## Notable Enhancements * Selective webhook events! When defining webhooks, you can choose which events should fire a webhook call. This makes the webhook much less chatty and easier to consume. * Further updates to Homepage and Folder overview pagination. * Action items updated in API Call History, Service Library, and Version Overview. * Further improvements to batch throughput. * Faster access to the backend storage of Spark services. * `Xreport` new API option for image border fix. * `Xreport` fix for invalid date format. * Security patch updates to address vulnerabilities, ensuring enhanced protection and stability of our systems. ## Version number `v8.54.1`
