What Changes in React Query v5?

At the time of writing, version 5.0.0-alpha.1 of @tanstack/react-query has just been released. While it might take a couple of weeks for the stable version to be released, when this book is published, it might already be the version that installs by default every time you add React Query to your project.

To make sure you understand the changes that the content of this book may undergo after v5 is released, this bonus chapter was added.

This chapter might also serve as a helper to guide you when migrating from v4 to v5.

Once again, as a disclaimer, the snippets of this chapter were tested on version 5.0.0-alpha.1 of @tanstack/react-query. Some of these things might still change, or some new ones might show up. Either way, the snippets will be kept updated online in the next couple of months until a stable version is released. You can find them on the GitHub repository mentioned in the Technical requirements section.
