• Added support for defining flow measuring devices as prescribed in FDS 6.7.8 and beyond.
• Added support for custom 2D and 3D Slice IDs.

General Changes

• Fixed a bug that allowed users to apply the PERIODIC FLOW ONLY Surface to Obstructions.
• Replaced the Orientation field with Normal of Solid for Solid-Phase devices in Tool Properties.
• Fixed a bug where root nodes in the navigation tree could be renamed.

Changes to Results

• Added a display of the selected occupant ID in the information bar when selecting occupants in Results.
• Added the Find Occupant by ID dialog to find occupants in Results.
• Updated the skybox dialog to make live updates to the scene. The skybox toolbar button now opens the dialog instead of showing/hiding the skybox.

NOTE: This is a patch release to fix a significant bug found in the 2022.3.1207 build that was removed from this site.
The bug was to click the Orbit or Roam tool and then single left-click in the modeling window, and PyroSim would crash. We released this patch release the following day to eliminate frustration, and potential data loss, with a bug that would likely be experienced frequently.
