This release supports FDS 6.8.0, adds rich support for HVAC systems in Results, makes UI and performance improvements, and fixes some bugs.
Improved FDS Support
This release prepares PyroSim for upcoming FDS features included in FDS 6.8 and 7.0.
These features include:
Problematic void pressure zone identification and filling
Multiple simple chemistry reactions
HVAC waypoints
HVAC visualization in Results
A new surface type for the 3D heat transfer feature in FDS
A redesigned FDS species library interface to accommodate an increase from 30 to roughly 350 species

Increased Interface Consistency
PyroSim, Pathfinder, and Results will all look and feel more similar to each other in 2023.1.
For the upcoming release, we have prioritized resolving many differences between these applications and how users interact with them.
Switching between the various interfaces should now feel more familiar.
Among the changes included are geometry render options selection (wireframe, solid, realistic, etc.), orthographic camera view selection, floor selection, and various action naming changes for consistency.
