Trigger Enter Event no longer works after update?

You will need to re-enable 2D and/or 3D Physics support using the new Welcome Window. We used to require that automatically and you had to disable it if not installed by manually entering compile time symbols to even get it to compile. Which was a bad experience.

The welcome window would have popped up automatically when you installed the update. If you told it to not auto-display, it will not come back automatically. Here's the documentation on the welcome window.

The release notes did mention this, and I make them very short so hopefully it doesn't take long to read them.

There's also a note at the top of the Event Sounds script documentation page that tells you this.

You just have to click the green question mark icon to get there from the Inspector

Thank you,
