Scenario File Updates

This page contains information on changes that could potentially break older scenarios, or otherwise cause unexpected behavior for users. In some cases it may be recommended that users not update mid mission, however all efforts will be made to avoid doing this or provide users with the tools to update their scenarios.

8.0 Beta, Build 1754, 2 November 2021

What changed: The way that vapor-pressure and enthalpy of vaporization are calculated by the internal systems simulation. Reference to forum thread: https://www.orbiter-forum.com/threads/v8-release-work-thread.36128/post-587754

User Action: None required.

Effect on Older Scenarios: Upon loading older scenarios the cabin temperature in the LM and CSM will rise sharply, but will return to nominal values within a few minutes. "O2 flow high" C/W alarms typically occur in the CSM too on initial load. Systems will stabilize on new internal states after this brief transition period and further saves in the same mission should not exhibit these transient temperatures and pressures.
