• #​15213 c775fce Thanks @​florian-lefebvre! - BREAKING CHANGE to the experimental Fonts API only

  Updates how the local provider must be used when using the experimental Fonts API

  Previously, there were 2 kinds of font providers: remote and local.

  Font providers are now unified. If you are using the local provider, the process for configuring local fonts must be updated:

  -import { defineConfig } from "astro/config";
  +import { defineConfig, fontProviders } from "astro/config";
  
  export default defineConfig({
      experimental: {
          fonts: [{
              name: "Custom",
              cssVariable: "--font-custom",
  -            provider: "local",
  +            provider: fontProviders.local(),
  +            options: {
              variants: [
                  {
                      weight: 400,
                      style: "normal",
                      src: ["./src/assets/fonts/custom-400.woff2"]
                  },
                  {
                      weight: 700,
                      style: "normal",
                      src: ["./src/assets/fonts/custom-700.woff2"]
                  }
                  // ...
              ]
  +            }
          }]
      }
  });

  Once configured, there is no change to using local fonts in your project. However, you should inspect your deployed site to confirm that your new font configuration is being applied.

  See the experimental Fonts API docs for more information.

• #​15213 c775fce Thanks @​florian-lefebvre! - Exposes root on FontProvider init() context

  When building a custom FontProvider for the experimental Fonts API, the init() method receives a context. This context now exposes a root URL, useful for resolving local files:

  import type { FontProvider } from "astro";
  
  export function registryFontProvider(): FontProvider {
    return {
      // ...
  -    init: async ({ storage }) => {
  +    init: async ({ storage, root }) => {
          // ...
      },
    };
  }

• #​15185 edabeaa Thanks @​EricGrill! - Add .vercel to .gitignore when adding the Vercel adapter via astro add vercel
