Scheduled Patch Contents for Validation 26.3.6

We will be moving forward with the scheduled patch for Validation 26.3.6 which will be available in the Staging environment on Tuesday, July 28, 2026 and Production environment on Tuesday, August 4, 2026. The key resolved bugs include the following:

Spotfire:

• Workflow calculations and decimal precision settings were not applied correctly after a previous upgrade. Users who experienced unexpected rounding or missing decimal places in workflow results will see this corrected.
• Curve-fit overlay visuals and graphs were not rendering in the Calculation Explorer. Users can now view curve-fit graphical overlays as expected.

Attention Signals One Customers: Spotfire Server will be unavailable for approximately 3 hours while maintenance is performed to address the resolved issues listed above. During this time, users will be unable to start new Spotfire sessions, and any active sessions will be interrupted. Please save any work before the maintenance window begins, as unsaved changes will be lost. Service will be restored immediately following completion of the maintenance window.

Note: Signals Notebook functionality on the Signals platform will remain available and is not affected by this maintenance.

Tables Templates:

• An issue where the system incorrectly prompted users with an "Update visualization configuration" message even when no changes had been made to Table Template visualization settings.

Microsoft Office online integration:

• The "Edit in PowerPoint for the Web" feature no longer loses its connection after approximately 25 minutes of use. The session timeout has extended to 1 hour and users will see a warning 10 minutes before the session expires. 
• The "Edit in Excel for the Web" feature no longer expires silently after 20 minutes. The session timeout has extended to 1 hour and users will see a warning 10 minutes before the session expires. 

The defects listed here represent our current assessment of customer-reported critical issues as of Monday, July 20, 2026. This list is preliminary and subject to change prior to the Staging deployment based on ongoing technical evaluation and prioritization. The final Patch Summary Report to be provided upon release will contain the authoritative list of all defect resolutions included in this patch.
