Minor Changes

• #​8808 2993055be Thanks @​delucis! - Adds support for an --outDir CLI flag to astro build

• #​8502 c4270e476 Thanks @​bluwy! - Updates the internal shiki syntax highlighter to shikiji, an ESM-focused alternative that simplifies bundling and maintenance.

  There are no new options and no changes to how you author code blocks and syntax highlighting.

  Potentially breaking change: While this refactor should be transparent for most projects, the transition to shikiji now produces a smaller HTML markup by attaching a fallback color style to the pre or code element, instead of to the line span directly. For example:

  Before:

  <code class="astro-code" style="background-color: #&#8203;24292e">
    <pre>
      <span class="line" style="color: #e1e4e8">my code</span>
    </pre>
  </code>

  After:

  <code class="astro-code" style="background-color: #&#8203;24292e; color: #e1e4e8">
    <pre>
      <span class="line">my code<span>
    </pre>
  </code>

  This does not affect the colors as the span will inherit the color from the parent, but if you're relying on a specific HTML markup, please check your site carefully after upgrading to verify the styles.

• #​8798 f369fa250 Thanks @​Princesseuh! - Fixed tsconfig.json's new array format for extends not working. This was done by migrating Astro to use tsconfck instead of tsconfig-resolver to find and parse tsconfig.json files.

• #​8620 b2ae9ee0c Thanks @​Princesseuh! - Adds experimental support for generating srcset attributes and a new <Picture /> component.
