 ### Changed
 - Update dependency to Clojure 1.7. [#59](https://github.com/apa512/clj-rethinkdb/pull/59)
 - The query parts of this library have been converted to use Clojure 1.7 Reader Conditionals. This means that you can generate queries in ClojureScript and run them on the server (be very careful with this!). [#59](https://github.com/apa512/clj-rethinkdb/pull/59)
