What happened to file data analyse?

Can someone explain what happened to file analyze in ChatGTP4-turbo? Until the recent “update” I was able to upload and analyze files, like word, PDFs etc. Now with the new “update” i can only upload images, this is not an update, this is a downgrade. Where is the actual file analyze gone and how do I access it? also the new “update” only outputs one image per prompt via Dalle3, it used to output 4, also a massive downgrade, as is the speed of this new model, its supposed to be faster right? what a joke, it types slower than me sometimes.
