I use Coda from Panic Inc for my coding. I just coded a regular HTML form using HTML5. At the top I have my doctype declared (ofcourse!) like this:

<!DOCTYPE html>

It is completely fine according to the W3 validator

But if I use the validator in Coda I get this message:

This interface to HTML5 document checking is obsolete. Use an interface to https://validator.w3.org/nu/ instead.

The method you used to check this document relies on an obsolete interface that will become permanently unavailable in the near future.

Now I am wondering what this means as I have not found much info on this. Anyone an idea of how or why this message is there? As far as I know doctype is still required to create a reliable webpage.

Thanks for any input!

It's not about the doctype, but about the validator.

The validator Coda is connecting to, validate.w3.org, has been deprecated in favour of validator.w3.org/nu/.
