Pydantic V2 Is Here!

The last few months have involved a whirlwind of work, and we're finally ready to announce to official release of Pydantic V2!

Getting started with Pydantic V2

To get started with Pydantic V2, install it from PyPI:

pip install -U pydantic

Pydantic V2 is compatible with Python 3.8 and above.

See the docs for examples of Pydantic at work.

Pydantic V2 Pre Release

We're excited to announce the first alpha release of Pydantic V2!

This first Pydantic V2 alpha is no April Fool's joke — for a start we missed our April 1st target date 😢. After a year's work, we invite you to explore the improvements we've made and give us your feedback. We look forward to hearing your thoughts and working together to improve the library.

For many of you, Pydantic is already a key part of your Python toolkit and needs no introduction — we hope you'll find the improvements and additions in Pydantic V2 useful.

If you're new to Pydantic: Pydantic is an open-source Python library that provides powerful data parsing and validation — including type coercion and useful error messages when typing issues arise — and settings management capabilities. See the docs for examples of Pydantic at work.

Pydantic V2 Plan

Updated late 10 Jul 2022, see pydantic#4226.

I've spoken to quite a few people about pydantic V2, and mention it in passing even more.

I owe people a proper explanation of the plan for V2:

  • What we will add
  • What we will remove
  • What we will change
  • How I'm intending to go about completing it and getting it released
  • Some idea of timeframe 😨
