# Release 2.6.2

Fixes an issue where `keras`, `tensorflow_estimator` and `tensorboard` were
missing proper upper bounds and resulted in broken installs after TF 2.7 release

# Release 2.6.1

This release introduces several vulnerability fixes:

*   Fixes a code injection issue in `saved_model_cli`

        session.release();

        session.release();
        assertFalse(session.isInUse(), "Session should not be in use after all releases");

        // Test multiple releases (should not throw)

## 0.112.4

This release is mainly a big internal refactor to enable adding support for Pydantic models for `Form` fields, but that feature comes in the next release.

This release shouldn't affect apps using FastAPI in any way. You don't even have to upgrade to this version yet. It's just a checkpoint. 🤓
