  7. There has been a general update to all the pages related to Model Behaviors to bring them in line with the MSFS 2024 standards. It is worth noting that the following pages are either new or have received a complete rewrite:
    1. Important Templates
      Using Model Behaviors
      Model Behaviors Parameters
      Model Behaviors Inputs
      Creating Cockpit Interactions (previously called "Creating Interactions With Input Events")
      Creating Interaction Tooltips
  8. The following parameters across various CFG files have been changed and no longer require a list, and instead take a hash-map: lightdef.N, point.N, interactive_point.N,
