See the new [GET](https://elevenlabs.io/docs/api-reference/workspace/dashboard/get) and [PATCH](https://elevenlabs.io/docs/api-reference/workspace/dashboard/update) endpoints for managing dashboard settings.
- **Call History Filtering**: Added the ability to filter the call history by start date using the new `call_start_before_unix` parameter in the [List Conversations](/guides/changelog-api-reference-conversations-list#request.query.call_start_before_unix) endpoint. [Try it here](https://elevenlabs.io/app/agents/history).

- **Transfer to number**: Added call forwarding functionality to support forwarding to operators, see docs [here](/guides/elevenagents-customization-tools-system-tools-transfer-to-number)
- **Language detection**: Fixed an issue where the [language detection system tool](/guides/elevenagents-customization-tools-system-tools-language-detection) would trigger on a user replying yes in non-English language.

### Usage Analytics

- **Custom Aggregation**: Added an optional `aggregation_interval` parameter to the [Get Usage Metrics](https://elevenlabs.io/docs/api-reference/usage/get) endpoint to control the interval over which to aggregate character usage (hour, day, week, month, or cumulative).
- **New Metric Breakdowns**: The Usage Analytics section now supports additional metric breakdowns including `minutes_used`, `request_count`, `ttfb_avg`, and `ttfb_p95`, selectable via the new `metric` parameter in the [Get Usage Metrics](https://elevenlabs.io/docs/api-reference/usage/get) endpoint. Furthermore, you can now get a breakdown and filter by `request_queue`.
