Prefect v2.0.0 Release Notes

  • 🚀 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. 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. Prefect 1.0 documentation is now hosted at docs-v1.prefect.io.

    ⬆️ Upgrading from Prefect 1.0

    🚀 Flows written with Prefect 1.0 will require modifications to run with Prefect 2.0. If you're using Prefect 1.0, please see our guidance on Discourse for explicitly pinning your Prefect version in your package manager and Docker, so that you can make the transition to Prefect 2.0 when the time is right for you. See our migration page to learn more about upgrading.

    ⬆️ Upgrading from earlier versions of Prefect 2.0

    🚀 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, the tutorial, or the discourse guide.
