3.4
----------------------
- Add an Array column type which uses database-native array types where possible (ie ARRAY for PostgreSQL).
3.3
-----------------------
- Add support for Python 3.3 and later.
- Modify UUID type to always use the native string type of the current Python version for its values.

-----------------------
- Make Session object easier to use: instead of creating it on initialisation create it immediately, and only configure it during initialisation. This makes it possible to import the Session directly.
