## Executive Summary (TL;DR)
Astro astro@6.2.0. Source highlight: Adds a `waitUntil` option to the `RenderOptions` so that adapters can forward runtime background-task hooks to Astro.

## New Features
- Adds a `waitUntil` option to the `RenderOptions` so that adapters can forward runtime background-task hooks to Astro.
