🍿 Minor Changes

• #12039 710a1a1 Thanks @ematipico! - Adds a markdown.shikiConfig.langAlias option that allows aliasing a non-supported code language to a known language. This is useful when the language of your code samples is not a built-in Shiki language, but you want your Markdown source to contain an accurate language while also displaying syntax highlighting.

  The following example configures Shiki to highlight cjs code blocks using the javascript syntax highlighter:

  import { defineConfig } from 'astro/config';
  
  export default defineConfig({
    markdown: {
      shikiConfig: {
        langAlias: {
          cjs: 'javascript',
        },
      },
    },
  });

  Then in your Markdown, you can use the alias as the language for a code block for syntax highlighting:

  ```cjs
  'use strict';
  
  function commonJs() {
    return 'I am a commonjs file';
  }
  ```

• #11984 3ac2263 Thanks @chaegumi! - Adds a new build.concurreny configuration option to specify the number of pages to build in parallel

  In most cases, you should not change the default value of 1.

  Use this option only when other attempts to reduce the overall rendering time (e.g. batch or cache long running tasks like fetch calls or data access) are not possible or are insufficient.

  Use this option only if the refactors are not possible. If the number is set too high, the page rendering may slow down due to insufficient memory resources and because JS is single-threaded.

  [!WARNING] This feature is stable and is not considered experimental. However, this feature is only intended to address difficult performance issues, and breaking changes may occur in a minor release to keep this option as performant as possible.

  import { defineConfig } from 'astro';
  
  export default defineConfig({
    build: {
      concurrency: 2,
    },
  });

🐞 Patch Changes

• #12160 c6fd1df Thanks @louisescher! - Fixes a bug where astro.config.mts and astro.config.cts weren’t reloading the dev server upon modifications.

• #12130 e96bcae Thanks @thehansys! - Fixes a bug in the parsing of x-forwarded-\* Request headers, where multiple values assigned to those headers were not correctly parsed.

  Now, headers like x-forwarded-proto: https,http are correctly parsed.

• #12147 9db755a Thanks @ascorbic! - Skips setting statusMessage header for HTTP/2 response

  HTTP/2 doesn’t support status message, so setting this was logging a warning.

• #12151 bb6d37f Thanks @ematipico! - Fixes an issue where Astro.currentLocale wasn’t incorrectly computed when the defaultLocale belonged to a custom locale path.
