To initiate a new Studio without installing the CLI globally:

npx create-sanity@latest

To upgrade a v3 Studio:

npm install sanity@latest

This is an internal change, but if you have RxJS as a dependency in your Studio project you should make sure to upgrade to v7 of RxJS in your package.json. Otherwise you may get build errors due to changes in the Observable interface between v6 and v7 (note: this is a type change only, and should not affect the runtime behavior of your studio).

If you get a build error saying something similar to:

TS2322: Type 'Observable<…>' is not assignable to type 'ObservableInput<any>'. 
  Type 'Observable<…>' is not assignable to type 'Observable<any>'. 
  The types of 'source.operator.call' are incompatible between these types. 
…

Then the solution is to upgrade the version of RxJS used in your project or library to 7.x. See the full list of breaking changes in RxJS 7

This is an internal change, but theoretically there might be small changes to how assets are handled between v3 and v4. If you're using custom Vite plugins or you are loading CSS or other files, please make sure they still work after the upgrade.
