# 6.164.0
June 25, 2026
## **What's New? 💡**
### **Data Studio**
* Labeling Agent — Added a reset action in the Review extension that allows reviewers, supervisors, and admins to clear a labeling agent’s work for a selected document and row range.
* Multi-channel Audio Labeling — When a timestamp label with overlapping timestamps across channels is selected and played on the main audio track, all corresponding timestamp labels are now highlighted across every channel.
* Actions — Added the ability to configure a separate External Object Storage (EOS) bucket as the output destination for action results, so actions can run even when the input bucket is read-only. The "result folder" field has also been renamed for clarity.
* Custom Report Builder — Introduced a new Cost group table in the Custom Report Builder, enabling workspaces to track AI inference costs incurred through Labeling Agent and ML-assisted labeling from LLM Labs. Users can now generate reports showing total inference cost (USD), average cost per label, and average cost per row, with breakdowns by date, member, project, project role, and document.
### **LLM Labs**
* Model Selection — Deprecated the Claude Sonnet 4 model and added the latest Claude model as a selectable option.
* File Sync — Added periodic sync support (hourly, daily, and custom schedules) for URL-based files, so their content is automatically reprocessed when it changes.
## **Bug Fixes 🐞**
### **Data Studio**
* Fixed an issue in Audio Labeling where timestamp labels disappeared after turning off the timestamp drawing button while drawing timestamps during audio playback.
* Fixed an issue in Span+Line Labeling where the "Answer matching lines" button in the Search extension was not centered.
* Fixed an issue on the Actions page where labeler and reviewer count showed incorrect pluralization (e.g. "1 Labelers" instead of "1 Labeler").
* Fixed an issue in Span Labeling where the Analytics extension did not count labels accepted by consensus toward a workspace member's “Accepted labels.”
* Fixed an issue in Span Labeling where the Analytics extension showed “Missed labels” as 0 when a reviewer manually applied a label.
### **LLM Labs**
* Fixed an issue in External Object Storage settings where the "Test Connection" action failed with an error for Google Drive, Azure, and SharePoint connections.
