# Upgrading to 0.27.0

If you haven't yet upgraded to `0.26.0`, please review the [0.26.0 upgrade
guide](/developer/upgrading/0.26.0) first.

`v0.27.0` of the runtime introduces support for multiple isolated Makeswift-enabled
React regions on a single page.

Since version 0.23, the runtime has included [built-in elements support](/developer/upgrading/0.23.0#built-in-elements),
allowing developers to define editable regions within a page. However, this capability
implicitly required all page regions to exist under a single React root and within
one [`<MakeswiftRuntimeProvider>`](/developer/reference/components/react-runtime-provider#reactruntimeprovider).
This release removes that limitation.

As part of this change,
`ReactRuntime` import for Next.js has been moved from `@makeswift/runtime/react` to `@makeswift/runtime/next`.

Refer to the [official release
notes](https://github.com/makeswift/makeswift/releases/tag/%40makeswift%2Fruntime%400.27.0)
for the full list of changes.

## Breaking Changes

### `ReactRuntime` import

`ReactRuntime` import for Next.js has been moved from `@makeswift/runtime/react` to `@makeswift/runtime/next`:

```diff theme={null}
- import { ReactRuntime } from '@makeswift/runtime/react';
+ import { ReactRuntime } from '@makeswift/runtime/next';

export const runtime = new ReactRuntime();
```

### (internal) `appOrigin` and `apiOrigin` params

Undocumented `appOrigin` and `apiOrigin` params are now passed directly to the `ReactRuntime` constructor.
See [internal apps](https://github.com/makeswift/makeswift/tree/@makeswift/runtime@0.27.0/apps) for details.
