I'm in the middle of putting together a changelog for the upcoming 3.1 release.

Just in case anyone needs to do this in the future, I've put together a quick script that interacts with the bitbucket REST API to generate a summary of all merged pull requests since the release of yt 3.0 on August 4th.

The script is here: https://bpaste.net/show/f86b1b4c0326

My plan now is to use the output of this script to manually create a changelog for the docs and release announcement.

Hope that's helpful,
