Navmesh updates look good, a step in the right direction, hopefully more to come. Niagara as well. Very interested in the Networking Insights.
Seeing a lot of “updates” in general in this release, rather than new features, yay, good stuff!
Perhaps this means a focus primarily on bug fixing and stability this time around? Maybe? Hopefully? Yes? PLEASE? 
Looks great. Really hoping the “Fixed in 4.25” list grows exponentially over the coming weeks.
