+# New Features & Enhancements
+
+1. **Enhanced Call [`Artifacts`](https://api.vapi.ai/api#:~:text=Artifact)**: You can now store detailed information about call workflows and outcomes using [`Artifact`](https://api.vapi.ai/api#:~:text=Artifact) objects. Key properties include:
+    - `nodes`: History of workflow nodes executed during the call.
+    - `messages`: All messages spoken during the call.
+    - `logUrl`: **New!** Direct URL to detailed call logs for debugging.
+    - `pcapUrl`: Packet capture URL for phone calls (provider: `vapi` or `byo-phone-number`).
+    - `recording`: Recording URL (requires `assistant.artifactPlan.recordingEnabled`).
+    - `transcript`: Convenient full call transcript.
+    - `variableValues`: Final workflow variable states.
+    - `messagesOpenAIFormatted`: Spoken messages, formatted for OpenAI.
+
+<Warning>
+    `recordingUrl`, `videoRecordingUrl`, `stereoRecordingUrl`, and `videoRecordingStartDelaySeconds` are now deprecated in favor of the new `recording` and related properties within the `Artifact` object.
+</Warning>
+
+2. **Improved Azure Speech Segmentation Tuning**: You can now fine-tune speech segmentation in your [`Azure Speech Transcriber`](https://api.vapi.ai/api#:~:text=AzureSpeechTranscriber) using `segmentationStrategy`, `segmentationMaximumTimeMs`, and `segmentationSilenceTimeoutMs` properties for better transcription control. This applies to both [`Azure Speech Transcriber`](https://api.vapi.ai/api#:~:text=AzureSpeechTranscriber) and [`Fallback Azure Speech Transcriber`](https://api.vapi.ai/api#:~:text=FallbackAzureSpeechTranscriber).
+
+<Warning>
+    The `segmentationMaxTimeMs` property in [`AzureSpeechTranscriber`](https://api.vapi.ai/api#:~:text=AzureSpeechTranscriber) has been replaced by `segmentationMaximumTimeMs` for consistency.
+</Warning>

+#### 🎤 New Gladia Transcription Provider Support
+1. **Custom vocabulary support**: Enable a custom vocabulary with [`Gladia`](https://api.vapi.ai/api#:~:text=GladiaTranscriber) using `Assistant.transcriber[provider="GladiaTranscriber"].customVocabularyEnabled`. You can also specify simple strings or detailed objects with fields for value, language, intensity, and alternative pronunciations using `Assistant.transcriber[provider="GladiaTranscriber"].customVocabularyConfig` - letting you fine-tune recognition of domain-specific terms.
+
+2. **Endpointing & Speech Threshold**: Configure endpointing time (wait time before considering speech ended) and speech sensitivity, enabling more accurate and responsive transcription with `Assistant.transcriber[provider="GladiaTranscriber"].endpointing` and `Assistant.transcriber[provider="GladiaTranscriber"].speechThreshold`.
+
+3. **Prosody & Audio Enhancer**: Optionally enable prosody (for transcribing non-verbal cues like laughter) and audio enhancement for improved accuracy with `Assistant.transcriber[provider="GladiaTranscriber"].prosodyEnabled` and `Assistant.transcriber[provider="GladiaTranscriber"].audioEnhancerEnabled`.
+
+4. **Flexible Language Detection**: Choose between manual and automatic language detection modes with `Assistant.transcriber[provider="GladiaTranscriber"].languageDetectionMode`.
+
+5. **Confidence Thresholds & Hints**: Discard low-confidence transcripts and provide context hints for improved accuracy with `Assistant.transcriber[provider="GladiaTranscriber"].confidenceThreshold` and `Assistant.transcriber[provider="GladiaTranscriber"].hints`.
