Hello  
I’m still using the Legacy Twitch API v5 for extension chat API. It’s due for shutdown on Feb 28th but I just started getting 404 “This API does not exist”.  
The reason I’m still using the deprecated API is due to the fact that Twitch4j is still using it.  
The Twitch4j team is working on bumping up the version but there’s no release yet.  
Will it please be possible to keep support for the extension chat API till Feb 28?

Thank you
