This release adds support for HTTP proxy in communication with license servers available as a service. The release also improves log statements and addresses a few production issues.

The detailed list of changes introduced in this release follows.
New Features
  • Added support for HTTP proxy in communication with license servers available as a service.
Fixed Problems
  • Do not send any outstanding audio data, including final message, if recognition is already completed.
  • Keep tracking of received messages from the service in order to determine a missing speech.phrase message and complete recognition with an error. The problem with missing speech phrase has been resolved by Microsoft in the meantime.
