->withHttpHeader('OpenAI-Beta', 'assistants=v1') to ->withHttpHeader('OpenAI-Beta', 'assistants=v2')

Just a quick fix and my code runs. but there still need to fix migration issues.

You can create client manually with beta header:

$client = OpenAI::factory()
    ->withApiKey($apiKey)
    ->withOrganization($organization)
    ->withHttpHeader('OpenAI-Beta', 'assistants=v2')
    ->make();

but it won't help because the class doesn't match the request/response

@gehrisandro, we are looking forward to its completion :D Is there any platform where we can buy you a coffee?

Do we have any kind of ETA on when these changes might be getting implemented? I'm in the middle of a big upgrade of our AI code and want to utilize this asap. I second @subet request too.
