We ended up [removing this API](https://github.com/react/react/pull/20037) because of these issues. We are working on a new version for the Interaction Tracing API (tentatively called Transition Tracing because it is initiated via `startTransition`) that solves these problems. diff --git a/src/content/blog/2024/04/25/react-19-upgrade-guide.md b/src/content/blog/2024/04/25/react-19-upgrade-guide.md index 1823ebdfb..6f918a2a9 100644 --- a/src/content/blog/2024/04/25/react-19-upgrade-guide.md +++ b/src/content/blog/2024/04/25/react-19-upgrade-guide.md @@ -24,7 +24,7 @@ To help make the upgrade to React 19 easier, we've published a `react@18.3` rele We recommend upgrading to React 18.3 first to help identify any issues before upgrading to React 19. -For a list of changes in 18.3 see the [Release Notes](https://github.com/facebook/react/blob/main/CHANGELOG.md#1830-april-25-2024). +For a list of changes in 18.3 see the [Release Notes](https://github.com/react/react/blob/main/CHANGELOG.md#1830-april-25-2024). </Note> @@ -38,7 +38,7 @@ In this post, we will guide you through the steps for upgrading to React 19: - [TypeScript changes](#typescript-changes) - [Changelog](#changelog) -If you'd like to help us test React 19, follow the steps in this upgrade guide and [report any issues](https://github.com/facebook/react/issues/new?assignees=&labels=React+19&projects=&template=19.md&title=%5BReact+19%5D) you encounter.

Örneğin, bir kullanıcının zaman çizelgesi başka bir kullanıcının zaman çizelgesinden *farklı içerik*'tir.
