Hi @warpcast, I realized your developer preview url for v1 frames changed.
Is this the new url for the developer preview of v1 frames?
https://warpcast.com/~/developers/frames-legacy?url=<my_url_here>

Is it identical to how it was as of last friday or are there any gotchas we should be aware of when using this new url?

Yes, you are right. warpcast.com/~/developers/frames-legacy is the new developer preview for v1 frames. As far as I know nothing in it changed, works just the same way on everything I have tested.
