Highlights

As of this release, Pydantic is an optional dependency.

What does that mean?
For you as an end user, not much; It is still supported in the same capacity as before, it's just not required anymore.
We have migrated all of our internals that previously relied on Pydantic (mainly for parsing and validation) to the amazing msgspec library, with Pydantic now being handled by an internal plugin.

The important thing is: Everything that has worked before with Pydantic will continue to work, and if you're not using Pydantic, but instead want to use attrs or pure msgspec, you won't have a required Pydantic dependency anymore.

Pydantic 2 support

Another change related to Pydantic is that this release adds support for Pydantic 2, which offers lots of improvements, new features and performance gains. Pydantic 1 is still fully supported and will be for the foreseeable future.
