3.1.1

* No changes.

3.1.0

* DataSource's sendRequest() argument signature has changed in a

non-backward-compatible way. It now accepts a single object containing

the properties "request", "callback", and "cfg".

* DataSource.Get bug fixed where it was trying to delete the proxy callback

in the wrong location during cleanup.

* Changed from array of proxy callbacks to object with guid keys to support

services that don't properly handle array indexes in the callback

parameter (Twitter)

* Code reorganized (API and functionality unaffected)

3.0.0

* DataSource.IO now passes request value to IO.

* DataSource.Function now catches exception and fires error event.

3.0.0 beta 1
