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.
