## 0.68.2

This release has **no breaking changes**. 🎉

It upgrades the version ranges of sub-dependencies to allow applications using FastAPI to easily upgrade them.

Soon there will be a new FastAPI release upgrading Starlette to take advantage of recent improvements, but as that has a higher chance of having breaking changes, it will be in a separate release.
