Which release version is actually the final version of cannon.js...?

[KLA6]

I was struggling with beginContact and collide events, because none of them was triggered in cannon.js v0.6.2.

And when I tried the cannon-es v0.20.0, I could see beginContact happens.

After that I had tried to check the codes of cannon.js v0.6.2, and I've realized that it doesn't have collision detection event patching.

But, I've seen Mr. Schteppe mentioned beginContact and collide on some issues on this repository.

So, I'm curious whether cannon.js v0.6.2 is not actually the final version of cannon.js...?

Or cannon.js needs additional codes for detecting collisions?

Thank you for reading my question.
