- [#4015](https://github.com/withastro/astro/pull/4015) [`6fd161d76`](https://github.com/withastro/astro/commit/6fd161d7691cbf9d3ffa4646e46059dfd0940010) Thanks [@matthewp](https://github.com/matthewp)! - New `output` configuration option
This change introduces a new "output target" configuration option (`output`). Setting the output target lets you decide the format of your final build, either:
-`"static"` (default): A static site. Your final build will be a collection of static assets (HTML, CSS, JS) that you can deploy to any static site host.
-`"server"`: A dynamic server application. Your final build will be an application that will run in a hosted server environment, generating HTML dynamically for different requests.
If `output` is omitted from your config, the default value `"static"` will be used.
When using the `"server"` output target, you must also include a runtime adapter via the `adapter` configuration. An adapter will _adapt_ your final build to run on the deployed platform of your choice (Netlify, Vercel, Node.js, Deno, etc).
To migrate: No action is required for most users. If you currently define an `adapter`, you will need to also add `output: 'server'` to your config file to make it explicit that you are building a server. Here is an example of what that change would look like for someone deploying to Netlify:
```diff
import { defineConfig } from 'astro/config';
import netlify from '@astrojs/netlify/functions';
export default defineConfig({
adapter: netlify(),
+ output: 'server',
});
```

The new `Astro.clientAddress` property allows you to get the IP address of the requested user.
```astro
<div>Your address { Astro.clientAddress }</div>
```
This property is only available when building for SSR, and only if the adapter you are using supports providing the IP address. If you attempt to access the property in a SSG app it will throw an error.

- [#3216](https://github.com/withastro/astro/pull/3216) [`114bf63e`](https://github.com/withastro/astro/commit/114bf63e11f28299b13178ef1a412eed37ab7909) Thanks [@JuanM04](https://github.com/JuanM04)! - **[BREAKING]** Now with Build Output API (v3)! [See the README to get started](https://github.com/withastro/astro/tree/main/packages/integrations/vercel#readme).
-`trailingSlash` redirects works without a `vercel.json` file: just configure them inside your `astro.config.mjs`
- Multiple deploy targets: `edge`, `serverless` and `static`!
- When building to `serverless`, your code isn't transpiled to CJS anymore.
**Migrate from v0.1**
1. Change the import inside `astro.config.mjs`:
```diff
- import vercel from '@astrojs/vercel';
+ import vercel from '@astrojs/vercel/serverless';
```
2. Rename the `ENABLE_FILE_SYSTEM_API` environment variable to `ENABLE_VC_BUILD`, as Vercel changed it.
3. The output folder changed from `.output` to `.vercel/output` — you may need to update your `.gitignore`.
