Congrats on the new release. Got one question, regarding production.

Can you give an estimate of when AU2 will be production-ready? I want to create a UI builder in Aurelia, but not sure when AU2 will be ready for production. This will be a visual website builder, so I don’t want any major issues preventing me from releasing it. I’m planning on starting work early next year.

We’ll likely be in RC stream after only few more betas maximum (I hope), there’s nothing blocking us anymore, and the new generated code for decorator seems to be doing fine.

For your business, I don’t think it’ll be greatly be affected by even beta version, we are actually quite stable now.
