nodeMiddleware experimental feature

[markdemich-fl]

Summary

I upgraded from NextJS 14 to 15 in hopes of enabling the feature to run middleware in nodejs. I'm not deploying to vercel so I don't think it should be a problem not use edge. This way I can have better support for logging libraries in my middleware. However, when I attempted to use it, it throws the following exception.

[CanaryOnlyError: The experimental feature "experimental.nodeMiddleware" can only be enabled when using the latest canary version of Next.js.]

I don't want to run the Canary version. I want to run the latest official version. Does anyone know when this will become a non-experimental feature. Is there any override to allow it to run in a non-canary version.
