Help writing release notes

[Aaron Meurer]

If anyone is free for the winter break and wants to help out, I could
really use some help getting together the release notes for the next
release https://github.com/sympy/sympy/wiki/Release-Notes-for-1.1.
Feel free to just edit that page.

We only need to list significant changes. Listing backwards compatible
changes and major changes is the most important. It's not a big deal
if the notes miss some minor changes.

The git command

git log --oneline 1.0..master --grep="Merge pull request"

will show all pull requests that have been merged since the release.
You can also get (roughly) the same thing here
https://github.com/sympy/sympy/pulls?utf8=%E2%9C%93&q=merged%3A%3E%3D2016-02-19%20is%3Apr%20
