Prefect

We have shipped a lot of breaking changes to Prefect 2.0 over the past week. Most importantly, **recent changes to deployments required that schedules for all previously created deployments be turned off**. You can learn more about the changes via the [deployments concept documentation](https://docs.prefect.io/concepts/deployments/), the [tutorial](https://docs.prefect.io/tutorials/deployments/), or the [discourse guide](https://discourse.prefect.io/t/deployments-are-now-simpler-and-declarative/1255).

We're thrilled to announce that, with this release, Prefect 2.0 has exited its public beta! Hopefully, this release comes as no surprise. It is the culmination of nearly a year of building in public and incorporating your feedback. Prefect 2.0 is now the default version of the open source `prefect` framework provided [upon installation](https://docs.prefect.io/getting-started/installation/). We will continue enhancing Prefect 2.0 rapidly, but future breaking changes will be less frequent and more notice will be provided.

Prefect 2.0 documentation is now hosted at [docs.prefect.io](https://docs.prefect.io). Prefect 1.0 documentation is now hosted at [docs-v1.prefect.io](https://docs-v1.prefect.io).
