[drakew...@gmail.com]

I'm pleased to announce the official release of Drake version 1.0.0. This release includes easy out-of-the-box installation, as well as a commemorative logo upgrade to call out version 1.0.0. 

Many thanks to @amalloy for his ownership, guidance and leadership with Drake's core codebase since he started at Factual.

Many thanks to @mavericklou for taking ownership of specific bugs & features and owning release management. Mav notably added a shiny new install/upgrade script, which makes it dead simple for Linux users to install and upgrade Drake.

And as always, thanks to everyone who ever contributed comments, suggestions, questions, tickets, and especially Pull Requests to the project!

Sincerely,

Aaron
