Version 6.1.12

Released May 15, 2026 - Bug fix: project files containing deeply nested state/node graphs now open correctly (previously blocked by a JSON parser depth limit).

Bug fixes

  • Saved project file fails to load with "It looks like the file you are trying to open is not a valid file" when the model contains deeply nested state/node structures (Newtonsoft JSON MaxDepth=64 limit exceeded).
