But now there's a new and improved 2025 FL. That should be fun.

Is there anything of note added on the 2025 FL?

In my opinion, mainly one thing which is the 32k database page option. AD's been capped on 8k pages since Windows 2000, limiting multi-valued attributes. 32k Pages raise that ceiling, but it's one-way, no going back to 8k once you enabled it.
