We have a warning filter for our internal tests to ignore warnings that are too noisy or that we haven't removed from our test suite yet: shouldIgnoreConsoleError. Many of our server rendering tests don't use this filter, though, because it has its own special of asserting warnings. So I added the warning filter to the server tests, too.
These are no longer supported in React 18. They are replaced by the `createRoot` API. The warning includes a link to documentation of the new API. Currently it redirects to the corresponding working group post. Here's the PR to set up the redirect: reactjs/react.dev#3730 Many of our tests still use ReactDOM.render. We will need to gradually migrate them over to createRoot. In the meantime, I added the warnings to our internal warning filter.

Maybe use "ReactDOM.render is deprecated in React 18" instead for consistent messaging? "not supported" sounds like it's no longer working. Unless the other deprecation warnings also use "not supported" instead of "deprecated".

* Use existing test warning filter for server tests We have a warning filter for our internal tests to ignore warnings that are too noisy or that we haven't removed from our test suite yet: shouldIgnoreConsoleError. Many of our server rendering tests don't use this filter, though, because it has its own special of asserting warnings. So I added the warning filter to the server tests, too. * Deprecate ReactDOM.render and ReactDOM.hydrate These are no longer supported in React 18. They are replaced by the `createRoot` API.

Is it weird that we say "no longer supported in React 18" as if it was ever supported in React 18?

ReactDOM.hydrate is deprecated in React 18.
