New Features

• Added support for an optional language parameter passed to a built-in grammar. Fixed interoperability with Aspect Prophecy. See the Section 4.2 in the Usage Guide.
• Added support for HTTP proxy.
• Set an alarm in the status file if the license server is not reachable for a certain period of time, but the service is not yet affected. Clear the alarm as soon as the license server becomes available. See Section 6.2 in the Usage Guide.

Fixed Problems

• Fixed processing of malformed parameters passed to a built-in grammar.
• If an annual node-bound license is used, the expiration time of the license could be provisioned incorrectly, requiring a restart of the service in order to continue normal operation.
• Make sure START-OF-INPUT is sent before sending RECOGNITION-COMPLETE with a completion cause set to 'no-match' or 'success'. Fixed interoperability with Cisco Broadworks media server.
• When license server is in use, fixed processing of a connection hang-up event occurred when a license refresh request is being sent to the license server. This event could result in a few seconds-long outage of the service.

Configuration Parameters

• Added a new attribute 'http-proxy' to the element 'ws-streaming-recognition'.
• Changed the default value of the attribute 'speech-start-timeout' from 300 ms to 50 ms.

Miscellaneous

• Updated the Usage Guide to reflect the changes introduced in this release.
• Patched the Libevent library to properly support communication via HTTP proxy. The resulted package is based on 2.1.8 and released as 2.1.9.
