Major Changes

• #​15819 cafec4e Thanks @​delucis! - Upgrade to Vite v8

Minor Changes

• #​17093 4585fe5 Thanks @​Princesseuh! - Replaces the import entrypoint of getContainerRenderer()

  A new container-renderer entrypoint exporting getContainerRenderer() has been added to the following integrations: React, Preact, Svelte, SolidJS, Vue, and MDX. This prevents bundlers from trying to bundle unrelated exports from the package root when only the Container API is used.

  If you are using the Container API, update your import statements to use the new entrypoint. The following example updates the getContainerRenderer() import for React:

  - import { getContainerRenderer } from '@​astrojs/react';
  + import { getContainerRenderer } from '@​astrojs/react/container-renderer';

  Importing getContainerRenderer() from the package root still works, but is now deprecated and logs a warning.

• #​17129 ff7b718 Thanks @​Princesseuh! - Adds support for modifying frontmatter programmatically with the default Markdown processor.

  A Sätteri plugin can now read and mutate ctx.data.astro.frontmatter, and Astro uses the result as the page's frontmatter, in both Markdown and MDX.

Patch Changes

• #​17124 7e7ab87 Thanks @​Princesseuh! - Updates satteri to 0.9.0. See the Sätteri changelog for details.

• #​17027 241250b Thanks @​ocavue! - Triggers beta prereleases for packages that are still on alpha
