The detailed list of changes introduced in this release follows.

New Features

• Allow to specify multiple 'deepgram.tag' parameters.
• When 'vad_events' is set to 'true', derive START-OF-INPUT from 'SpeechStarted' event.
• Use 'speech_final' flag as an indication of input completion when 'single-utterance' is set to 'false'.

Fixed Problems

• Skip processing of new messages received from Deepgram when connection is closing.
• Make sure the keep-alive timer is properly stopped when start-of-input is set to internal. This issue could possibly cause a segfault.

Configuration Parameters

• None.

Miscellaneous

• None.
