I just want to take a moment to brag that I'm GMing my first D&D group in years and it's going really well, five sessions in. It's a wonderful feeling to be actively looking forward to the next session again, and I've really missed this.

The campaign I'm running is Pathfinder. I know basically nothing about Pathfinder 2.0 but I'm aware it's a thing. What's it meant to do, and when's its expected release?
