Released on February 27, 2014

- Previously the error message was set based on the `tty` value; instead now we
detect `tty` when you try to print the error message. The `msg` property of
the exception is set to a decent value.
- `twilio-python` now uses entirely relative imports, so it may be easier to
include it as a part of another package.

instance classes.
