3.9.0 – October 14, 2026
New Features:
-
CTI: Added Time Overcurrent (TOC) as a valid coordination type for CTI studies
-
T-Line: Added ability to run settings development workflow for zero-length lines
-
T-Line: Added PRC-026 check in Settings Calibration tab for verification of performance during stable power swings
-
WAC: Added ability to run freeform equations study with reference to branch rather than a specific relay
-
Export to RDB: Added ability to select which group to export settings
-
Faults: Added “Remote End” option to simulate the fault as if the local and remote ends of the current branch are flipped
-
Added Auto-Backup for recovery of project and template files in case of crash
Usability/Interface Improvements:
-
T-Line: Improved message for testing points when relays are missing required elements
-
WAC: SARA Dictionary values show on hover in WAC template editor
-
WAC: Improved speed of loading WAC Dashboard
-
WAC: Display list of relays that are omitted from reach comparison studies because they are ‘OFF’
-
WAC: Added error handling when user changes auto-solve .stl link for equations studies
-
WAC: improved speed of generating aggregate report
Bug Fixes:
-
T-Line: Fault overrides were removed if user changed a user variable
-
T-Line: Relay Variables didn’t appear if only used in a flag and not a settings equation
-
T-Line: Changes to CTI configuration didn’t save in T-Line Template
-
T-Line: Deleting relay in the relay manager if a card depended only on that relay caused crash
-
WAC: Slider didn’t match setting if Auto-Solve could not find solution
-
WAC: CTI studies sometimes opened to a blank screen
-
WAC: WAC Dashboard failed to load on cases where all constraints triggered skip conditions
-
WAC: CTI visual still showed violations after all violations were resolved
-
WAC: Auto-Solve could suggest setting outside of valid setting ranges
