Make `.safe()` the default return value for actions. This means `{ data, error }` will be returned when calling an action directly. If you prefer to get the data while allowing errors to throw, chain the `.orThrow()` modifier.
- Remove `.safe` from existing _safe_ action calls
- Add `.orThrow` to existing _unsafe_ action calls

Updates the Astro Actions fallback to support `action={actions.name}` instead of using `getActionProps().` This will submit a form to the server in zero-JS scenarios using a search parameter:
```astro
---
import { actions } from 'astro:actions';
---
<formaction={actions.logOut}>
<!--output: action="?_astroAction=logOut"-->
<button>Log Out</button>
</form>
```
You may also construct form action URLs using string concatenation, or by using the `URL()` constructor, with the an action's `.queryString` property:
```astro
---
import { actions } from 'astro:actions';
const confirmationUrl = new URL('/confirmation', Astro.url);
`getActionProps()` is now deprecated. To use the new fallback pattern, remove the `getActionProps()` input from your form and pass your action function to the form `action` attribute:

Use this function to manually store renderers inside the instance of your container.
This new function should be preferred when using the Container API in environments like on-demand pages:
```ts
import type { APIRoute } from 'astro';
import { experimental_AstroContainer } from 'astro/container';
import reactRenderer from '@astrojs/react/server.js';
import vueRenderer from '@astrojs/vue/server.js';
import ReactComponent from '../components/button.jsx';
import VueComponent from '../components/button.vue';
// MDX runtime is contained inside the Astro core
import mdxRenderer from 'astro/jsx/server.js';
// In case you need to import a custom renderer

This introduces progressive enhancement when calling an Action with the `withState()` utility.
This example calls a `like` action that accepts a `postId` and returns the number of likes. Pass this action to the `experimental_withState()` function to apply progressive enhancement info, and apply to `useActionState()` to track the result:
```tsx
import { actions } from 'astro:actions';
import { experimental_withState } from '@astrojs/react/actions';
export function Like({ postId }: { postId: string }) {
You can also access the state stored by `useActionState()` from your action `handler`. Call `experimental_getActionState()` with the API context, and optionally apply a type to the result:
```ts
import { defineAction, z } from 'astro:actions';
import { experimental_getActionState } from '@astrojs/react/actions';

Also adds a new view transitions option `transition:persist-props` (default: `false`) to prevent props from updating as needed.
Islands which have the `transition:persist` property to keep their state when using the `<ViewTransitions />` router will now have their props updated upon navigation. This is useful in cases where the component relies on page-specific props, such as the current page title, which should update upon navigation.
For example, the component below is set to persist across navigation. This component receives a `products` props and might have some internal state, such as which filters are applied:
Upon navigation, this component persists, but the desired `products` might change, for example if you are visiting a category of products, or you are performing a search.
Previously the props would not change on navigation, and your island would have to handle updating them externally, such as with API calls.
With this change the props are now updated, while still preserving state.
You can override this new default behavior on a per-component basis using `transition:persist-props=true` to persist both props and state during navigation:

This change introduces a new flag that renderers can add called `supportsAstroStaticSlot`. What this does is let Astro know that the render is sending `<astro-static-slot>` as placeholder values for static (non-hydrated) slots which Astro will then remove.
This change is completely backwards compatible, but fixes bugs caused by combining ssr-only and client-side framework components like so:
```astro
<Component>
<div>
<Componentclient:load>
<span>Nested</span>
</Component>
</div>
</Component>
```
