Added

• Added Core-Language parameter to the QnABot deployment. This parameter allows the user to select during the deployment a core language which will be used by the OpenSearch language analyzers to look for question and answers. With this update, QnABot can now be deployed natively in 33 Languages with a more syntactical accuracy for matching questions and answers
• Bot routing enhancements including passing initial utterance to specialty bot and receive session attributes from specialty bot (issue #376) - contributed by (@bobpskier)
• Improved error handling. Added custom error handling question to QnaUtility and some errors are appended to chat client message when ENABLE_DEBUG_RESPONSES is set to 'true'
• Added 'PROTECTED_UTTERANCES' setting which allows the user to configure a comma-separated list of utterances that will be ignored by LLM query disambiguation and translation. This fixes a bug where feedback (thumbs up/thumbs down) and language selection would be disambiguated instead of triggering the respective workflow
• Added 'getQuestion' handlebar that returns the original matched question without hard-coding (issue #397)
• Added functional test collection for verifying deployed QnABots
• Added Service API Usage Tracking
• Added deployment parameter to enable selection of opensearch instance type (issue #599)
