#15192 ada2808 Thanks @gameroman! - Removes support for CommonJS config files - (v6 upgrade guidance)
#15266 f7c9365 Thanks @florian-lefebvre! - Allows Astro.csp and context.csp to be undefined instead of throwing errors when csp: true is not configured
When using the experimental Content Security Policy feature in Astro 5.x, context.csp was always defined but would throw if experimental.csp was not enabled in the Astro config.
For the stable version of this API in Astro 6, context.csp can now be undefined if CSP is not enabled and its methods will never throw.
What should I do?

If you were using experimental CSP runtime utilities, you must now access methods conditionally:
```
-Astro.csp.insertDirective("default-src 'self'");
+Astro.csp?.insertDirective("default-src 'self'");
```

#15208 8dbdd8e Thanks @matthewp! - Makes session.driver optional in config schema, allowing adapters to provide default drivers
Adapters like Cloudflare, Netlify, and Node provide default session drivers, so users can now configure session options (like ttl) without explicitly specifying a driver.
