• Describe the current behavior:

Now I can track only the dependencies of google-colab by reading history of setup.py. For example, today I know it has updated tornado to 5.1 which resolve problems with many other libraries.

For other libraries, I can manually call !pip freeze to get the current state. But I want to track diffs and history as well.

For example, someone mentions that holoviews is now supported in Colab. I want to be able to track that or any other libraries. Then, I can write an article to promote a new library just available in Colab.

• Describe the expected behavior:

requirements.txt or equivalent information is provided through github as well.
