"Improved AI tools" and returned web builds since UE 4.24 I really wanted in the same sentence
It’s official: 5.9 is happening and it's coming in Preview next week.
It’ll include improved AI workflows, web as a target platform, rendering and animation updates, plus more.
We’re making a few changes in 5.9 branch over on GitHub, and more will come in over the next few days. More details coming soon!
