What is the difference between Isaac Sim 4.0.0 and Isaac Sim 4.1.0?

Hey, guys:

I have 3 questions about developing standalone programs with Isaac Sim. They are as follows:

  1. What is the difference between Isaac Sim 4.0.0 and Isaac Sim 4.1.0?
  2. Where is the path to libomni.kit.converter.hoops?
  3. If I want to use a standalone program to convert CAD files (e.g., *.iges, *.ige), what is the recommended approach?

BR.
