Release Notes

ReactTraining/react-router

### [`v5.2.1`](https://togithub.com/ReactTraining/react-router/releases/v5.2.1) [Compare Source](https://togithub.com/ReactTraining/react-router/compare/v5.2.0...v5.2.1) This release fixes a bug with `` so that, when the `to` location is the same as the current, the history state entry is replaced instead of pushed to the stack. See [https://github.com/remix-run/react-router/issues/5362](https://togithub.com/remix-run/react-router/issues/5362) for details. 🥳 Thanks to [@​guidobouman](https://togithub.com/guidobouman) for the PR and for everyone else who weighed in for the fix!
