  * Suppresses some spurious log lines when tests are run

### v3.2.0 (2016-05-23)

  * Updates the `_makeAPICall` method to make the optional API args param optional to pass in, so the third param to this function can be either an opts object or a cb. This is to allow us to add optional arguments to API methods without it being a breaking change.

  * New methods are added to various facets:
    - [`files.revokePublicURL`](/lib/clients/web/facets/files.js)

  * Fixes the way `getAPICallArgs` works, to correctly pull data out of the `opts` arg

### v2.1.0 (2016-03-05)

  * Updates the way that API requests are throttled to:
    * avoid a condition where the request queue callback could be called multiple times, causing a crash
    * refactor the logic in `_callTransport` into multiple functions to make it easier to follow
  * Updates dev dependencies:
    * eslint
    * nock

  Refactors the library to javascript, adds a lot of tests and restructures it to improve maintainability and extend functionality.

    - Web; provideas a callback interface to all of Slack's Web API endpoints

  * Uncouples the model objects from the clients; model functions to send messages to channels etc are now accessed via the web and RTM client
