Patch Changes

• #​11678 34da907 Thanks @​ematipico! - Fixes a case where omitting a semicolon and line ending with carriage return - CRLF - in the prerender option could throw an error.

• #​11535 932bd2e Thanks @​matthewp! - Encrypt server island props

  Server island props are now encrypted with a key generated at build-time. This is intended to prevent accidentally leaking secrets caused by exposing secrets through prop-passing. This is not intended to allow a server island to be trusted to skip authentication, or to protect against any other vulnerabilities other than secret leakage.

  See the RFC for an explanation: https://github.com/withastro/roadmap/blob/server-islands/proposals/server-islands.md#props-serialization

• #​11655 dc0a297 Thanks @​billy-le! - Fixes Astro Actions input validation when using default values with a form input.

• #​11689 c7bda4c Thanks @​ematipico! - Fixes an issue in the Astro actions, where the size of the generated cookie was exceeding the size permitted by the Set-Cookie header.
