Release Candidate v0.3.0-rc.0 is published!

[brainlid]

There are some breaking changes around how callbacks work. See the CHANGELOG for details and migration steps.

Another breaking change is with ChatGoogleAI where the version field was renamed to api_version.

With the callback changes, now we have the ability to get API response headers with rate limits information. We also get token usage information!

Please try it out and open issues with any problems you encounter. Thank you for using the library and contributing to our growing little band. 🙂

I have been running 0.3.0-rc.0 for a couple weeks now and no issues to report. I am using the token_usage callback and it also seems to be working. I also checked the OpenAI billing dashboard to compare and it all seemed to match perfectly.

@brainlid what do you think of expanding documentation in this direction main...tubedude:langchain:docs
In this specific case I wanted to highlight required and optional parameters.

What to think of an AI library without AI generated documention? :)

Ha! I kinda like it. It feels like there's a few issues though. Like the documentation is indented by 2 spaces which it shouldn't be.

While handy, my main hesitance in creating a lot of doc text is that I didn't write it but have to maintain it. 😄 But having docs is good too. Feeling a little conflicted.
