WebVTT 1.0 is part of the deliverables of the Timed Text WG
The Timed Text WG charter has been updated in March 2014. It includes delivery of a WebVTT 1.0 specification as a W3C Recommendation.
This means, a snapshot of the WebVTT specification has been taken, FSA commitments have been made, and the specification was submitted to the Timed Text WG as input to the standardization process. All features in this snapshot will now be tested across the different implementations, in particular across browsers. Those features that have been implemented interoperably will be taken to Recommendation over the next year.
This Community Group will continue to work on the WebVTT specification to address new features and collaborate with the Timed Text WG on any bugs found with the submitted specification.
