# v2.0.0

* Breaking: prefer programatic (user-supplied) credentials over bluemix-provided ones (VCAP_SERVICES)

## Breaking Changes for v1.0

Several breaking changes were introduced with the v1.0.0 release:

  * Experimental and Beta services now require the appropriate tag to be added to their version:
    * Concept Expansion `v1` is now `v1-beta`
    * Question and Answer `v1` is now `v1-beta`
    * Relationship Extraction `v1` is now `v1-beta`
    * Tone Analyzer `v3` is now `v3` (latest) or `v3-beta` (compatibility with old Beta plan)
    * Visual Insights `v1` is now `v1-experimental`
    * Visual Recognition `v1` is now `v1-beta`
  * Speech to Text gained a new `createRecognizeStream()` method replacing the existing live streaming methods with a simpler Read/Write stream.
    The older methods are still available in v1.0 but each log a deprecation warning (unless `{silent: true}` is passed in) and will be removed from a future release.
    The affected methods are:
    * `recognizeLive()`
    * `observeResult()`
    * `getRecognizeStatus()`
  * The Document Conversion API has been reduced to a single `convert()` method; it no longer offers batch conversion or cloud storage of files.
  * Several deprecated services have been removed:
    * Message Resonance
    * Tone Analyzer v1 and v2 (replaced by v3)
    * Search (replaced by Retrieve and Rank)
  * Dropped support for node.js v0.10.x (For reference: the WDC Node.js SDK now officially support the latest 0.12, LTS, and Stable releases of Node.js.)
