As agreed upon in #1085 (comment).

I adapted things from a015a68 (the 0.14.0 one).

I concur, it's a bit of work to create the CHANGELOG.

We've merged 26 PRs since v0.14, of which 14 are currently mentioned in the changelog:

We don't need to mention all of these (e.g., typo fixes and minor internal changes unlikely to cause breakage), and there's a few items currently in the changelog that I think could be elided, but a few unmentioned PRs stand out to me as warranting mention:

Can you move the 'Breaking' section before 'Changed'?

Generally speaking, I don't think we should bother including documentation improvements in the changelog, unless the change is semantic, e.g., guaranteeing that a function never panics. In those cases, the bullet point should be quite specific about the new guarantee provided.

The role of the changelog is mostly for answering the question "my code broke when I updated, what might be the culprit".

@jswrenn I hope I got all of them.

Nice command line btw - maybe we should add it to the repo for next time?

I always leaned towards including also minor PRs (to give the authors credit), but I'm fine with restricting it.
