Is Blender still free?

I'm curious, is Blender still a free and open-source software program? I remember using it years ago for some 3D modeling and animation projects and was impressed with its capabilities. However, with the passage of time, I'm wondering if the software has changed its licensing model or if there are now any costs associated with using it. Could you please clarify the current status of Blender's availability and whether it remains accessible to users without any financial obligation?
