Summary & Key Takeaways ​

• Server functions now have configurable bodySizeLimit and maxArguments to prevent oversized payloads.
• Error stack disclosure can be explicitly controlled with serializeErrorStacks regardless of NODE_ENV.
• The selectedcontent HTML element is added to JSX intrinsic element types.
• Redirect and revalidate helpers now enforce Location and X-Revalidate header bounds at the transport edge.

Our Commentary ​

SolidJS continues to refine its server-side story, and these RC updates are all about robustness and security. I'm particularly glad to see the explicit control over error stack serialization; that's a common footgun. The argument limits for server functions are also a smart move to prevent abuse or accidental resource exhaustion. It's all about making the framework more resilient in production.
