Major Changes

#8113 2484dc408 Thanks @Princesseuh! - This import alias is no longer included by default with astro:assets. If you were using this alias with experimental assets, you must convert them to relative file paths, or create your own import aliases.
```
---
// src/pages/posts/post-1.astro
- import rocket from '~/assets/rocket.png'
+ import rocket from '../../assets/rocket.png';
---
```

#7979 dbc97b121 Thanks @bluwy! - Export experimental dev, build, preview, and sync APIs from astro. These APIs allow you to run Astro's commands programmatically, and replaces the previous entry point that runs the Astro CLI.

While these APIs are experimental, the inline config parameter is relatively stable without foreseeable changes. However, the returned results of these APIs are more likely to change in the future.

import { dev, build, preview, sync, type AstroInlineConfig } from 'astro';

// Inline Astro config object.
// Provide a path to a configuration file to load or set options directly inline.
const inlineConfig: AstroInlineConfig = {
  // Inline-specific options...
  configFile: './astro.config.mjs',
  logLevel: 'info',
  // Standard Astro config options...
  site: 'https://example.com',
};

// Start the Astro dev server
const devServer = await dev(inlineConfig);
await devServer.stop();

// Build your Astro project
await build(inlineConfig);

// Preview your built project
const previewServer = await preview(inlineConfig);
await previewServer.stop();

// Generate types for your Astro project
await sync(inlineConfig);

#8085 68efd4a8b Thanks @bluwy! - Remove exports for astro/internal/* and astro/runtime/server/* in favour of astro/runtime/*. Add new astro/compiler-runtime export for compiler-specific runtime code.

These are exports for Astro's internal API and should not affect your project, but if you do use these entrypoints, you can migrate like below:

- import 'astro/internal/index.js';
+ import 'astro/runtime/server/index.js';

- import 'astro/server/index.js';
+ import 'astro/runtime/server/index.js';

import { transform } from '@astrojs/compiler';

const result = await transform(source, {
- internalURL: 'astro/runtime/server/index.js',
+ internalURL: 'astro/compiler-runtime',
  // ...
});

#8030 5208a3c8f Thanks @natemoo-re! - Removed duplicate astro/dist/jsx export. Please use the astro/jsx export instead
#8118 8a5b0c1f3 Thanks @lilnasy! - Astro is smarter about CSS! Small stylesheets are now inlined by default, and no longer incur the cost of additional requests to your server. Your visitors will have to wait less before they see your pages, especially those in remote locations or in a subway.
This may not be news to you if you had opted-in via the build.inlineStylesheets configuration. Stabilized in Astro 2.6 and set to "auto" by default for Starlight, this configuration allows you to reduce the number of requests for stylesheets by inlining them into <style> tags. The new default is "auto", which selects assets smaller than 4kB and includes them in the initial response.
To go back to the previous default behavior, change build.inlineStylesheets to "never".
```
import { defineConfig } from 'astro/config';

export default defineConfig({
  build: {
    inlineStylesheets: 'never',
  },
});
```
#7921 b76c166bd Thanks @Princesseuh! - astro:assets is now enabled by default. If you were previously using the experimental.assets flag, please remove it from your config. Also note that the previous @astrojs/image integration is incompatible, and must be removed.
This also brings two important changes to using images in Astro:
- New ESM shape: importing an image will now return an object with different properties describing the image such as its path, format and dimensions. This is a breaking change and may require you to update your existing images.
- In Markdown, MDX, and Markdoc, the ![]() syntax will now resolve relative images located anywhere in your project in addition to remote images and images stored in the public/ folder. This notably unlocks storing images next to your content.
Please see our existing Assets page in Docs for more information about using astro:assets.

Minor Changes

#8101 ea7ff5177 Thanks @matthewp! - astro:namespace aliases for middleware and components
This adds aliases of astro:middleware and astro:components for the middleware and components modules. This is to make our documentation consistent between are various modules, where some are virtual modules and others are not. Going forward new built-in modules will use this namespace.

Patch Changes

#8128 c2c71d90c Thanks @Princesseuh! - Update error message when Sharp couldn't be found (tends to happen on pnpm notably)
#8092 7177f7579 Thanks @natemoo-re! - Ensure dotfiles are cleaned during static builds
#8070 097a8e4e9 Thanks @lilnasy! - Fix a handful of edge cases with prerendered 404/500 pages
#8078 2540feedb Thanks @alexanderniebuhr! - Reimplement #7509 to correctly emit pre-rendered pages now that build.split is deprecated and this configuration has been moved to functionPerRoute inside the adapter.
#8105 0e0fa605d Thanks @martrapp! - ViewTransition: bug fix for lost scroll position in browser history
#7778 d6b494376 Thanks @y-nk! - Added support for optimizing remote images from authorized sources when using astro:assets. This comes with two new parameters to specify which domains (image.domains) and host patterns (image.remotePatterns) are authorized for remote images.
For example, the following configuration will only allow remote images from astro.build to be optimized:
```
// astro.config.mjs
export default defineConfig({
  image: {
    domains: ['astro.build'],
  },
});
```
The following configuration will only allow remote images from HTTPS hosts:
```
// astro.config.mjs
export default defineConfig({
  image: {
    remotePatterns: [{ protocol: 'https' }],
  },
});
```
#8072 4477bb41c Thanks @matthewp! - Update Astro types to reflect that compress defaults to true
#8130 3e834293d Thanks @Princesseuh! - Add some polyfills for Stackblitz until they support Node 18. Running Astro on Node 16 is still not officially supported, however.
Updated dependencies [3e834293d]:
- @astrojs/telemetry@3.0.0-beta.2
