+Adds a configuration option to disable CLI telemetry for the project
+
+Astro collects optional anonymous telemetry to help us understand how people use the CLI. This change adds a new way to disable telemetry on a per-project basis. Currently you can disable telemetry globally per machine by running `astro telemetry disable` or by setting the environment variable `ASTRO_TELEMETRY_DISABLE`. This change adds a new configuration option to disable telemetry for a specific project, which applies to all users of the project.

+// astro.config.mjs
