What's the road to v1.0

[bajtos]

I love the idea of running Jest tests directly in Node.js environment with no virtualisation 👏🏻

However, I am reluctant to depend on projects that haven't reached 1.0 version.

What are your criteria for the 1.0 milestone? Are there specific features that need to be implemented, bugs to be fixed, APIs to be stabilised?

Since Babel and Prettier are already using this project "in production", maybe it's already time to bump the version to 1.0?
