+Enable Vercel Speed Insights and Vercel Web Analytics individually.
+Deprecates the `analytics` property in `astro.config.mjs` in favor of `speedInsights` and `webAnalytics`.
+
+If you're using the `analytics` property, you'll need to update your config to use the new properties:
+
+```diff
+// astro.config.mjs
+export default defineConfig({
+ adapter: vercel({
+- analytics: true,
++ webAnalytics: {
++ enabled: true
++ },
++ speedInsights: {
++ enabled: true
++ }
+ })
+});
+```
+
+Allow configuration of Web Analytics with all available configuration options.
+Bumps @vercel/analytics package to the latest version.
