A quiet day in the Pydantic repo: one theoretical breaking change to model_config worth reading the blogpost for, and a handful of CI and docs cleanups.
Do not mutate `model_config` attribute pydantic/pydantic
Pydantic no longer mutates the model_config attribute you define on a model, so anything that read back the resolved config off the class will now see only what you wrote. The PR flags this as a theoretical breaking change and calls for a blogpost entry to document it.
Remove Mkdocs `social` plugin pydantic/pydantic
The Mkdocs social plugin is gone from the docs build, pulled because font fetches in CI had become flaky.
Fix PyPy 8.0.0 test failure (#13863) pydantic/pydantic
A test failure under PyPy 8.0.0 was fixed, keeping that interpreter combination on the supported matrix.
Drop the dead plugin-usage admonition from the plugin module doc (#13829) pydantic/pydantic
The plugin module docs lost a dead plugin-usage admonition, so the module reference no longer promises usage guidance it doesn't give.
Remove Mkdocs `social` plugin (#13865) pydantic/pydantic
The social plugin removal landed on main as well, completing the cleanup.
