Looks really good to me! I'm just made a couple of very minor comments inline at: ​https://github.com/django/django/pull/58/files

As a general comment, I think it might be worth adding a small paragraph at the beginning of that page explaining how the deprecation process works in Django (e.g. what the word "deprecation" means in this context; quiet vs. loud deprecation warnings, etc.). What do you think?

Looks great, thanks for your work on this! I also reviewed and made some inline comments on the pull request.

Julien, I think that more general information about the deprecation process is already present in the release-process documentation, and that's linked from the top of the deprecation timeline. Seems adequate that way to me?

[Preston Holmes]

updated pull request with inline comments, thanks guys.

RE deprecation process, I think only thing missing is a short mention that the process will be accelerated in rare cases, or for security reasons, but such clarification is not critical.

ready for additional review or checkin

[Carl Meyer]

Added three or four more minor notes, but this is almost ready IMO.
