The release provides a few fixes and improvements in the existing functionality.

The detailed list of changes introduced in this release follows.

New Features

• Made HTTP request timeout configurable.
• Allow voice name be also specified via Vendor-Specific-Parameters using the 'voice-name' token.

Fixed Problems

• Fixed a possible memory leak on processing the second and consecutive SPEAK requests in the scope of a single MRCP session.
• Fixed a possible segfault encountered on the MRCP session termination when a response to the ongoing speech synthesis request is delayed.
• Fixed a race condition in processing of the STOP request and the SPECH-COMPLETE event which could possibly cause a license depletion.
• Fixed a possible segfault on processing the header field Logging-Tag having an empty [no] value.

Configuration Parameters

• Added new attributes 'request-timeout' and 'auth-request-timeout' to the element 'synth-settings'. The attributes default to 30 seconds.
