@blindcat97, actually Physics and Particles in Blender have hardly changed in years, and all the information in this course is still relevant.
The most changes in this area have been with the UI.
We do recommend learning with the version of Blender used in the course to eliminate the frustration of these UI changes to the software.
Remember you are learning 3D/CG, Blender is the software we choose, each version of Blender is a tool to assist in our learning.
Just because v4.x is the latest version of Blender, there is no rule that says you have to use it.
I know of many professional artists still using v3.0 and earlier, because they have no need to change version.
They are obviously comfortable with the version they use, and it does what they need it to do.
The reason the Physics and Particles systems have not changed is because the Blender developers have been working on the new Simulation nodes system.
We do have a new course called Particles: Introduction to Simulation Nodes which you may be interested in.
You may have seen a famous Donut tutorial on YouTube, and the many iterations of it, using each new version of Blender as they are released,
but the result is the same, it’s still a Donut whatever the version.
