  ## langsmith-0.13.39

  * Users can now run experiments without `projects:create`, decoupling experiment execution from project governance controls.
  * Added skeleton loading state when switching between agent chat threads instead of a blank chat input.
  * Improved the Fleet Arcade integrations page to display correct actions and clearer backend states.
  * Arcade gateway installs now automatically sanitize invalid MCP server names before adding them to a workspace.
  * Users can now see assigned reviewers as name chips in the annotation queue list and filter to queues they are assigned to via an "Assigned to me" button.
  * Improved run details hover on the trace tree for less flicker when clicking or moving quickly between rows.
  * Fixed a timeout when generating Insights reports with feedback enabled on high-volume workspaces.
  * Arcade integrations now show a permission error instead of a generic upstream failure when a connected user lacks access to the configured Arcade project.
  * Added a clickable ID badge to the experiment detail page header for easy copying of the experiment ID.
  * LLM auth proxy JWTs now include `organization_name` and `workspace_name` claims.
  * Added dataset split selection to the evaluator playground, allowing users to run evaluator experiments on specific dataset splits.
  * Fixed experiment comparison view showing contradictory improvement arrows and regression cell colors for composite scores.
  * Fixed a bug where deleting traces from pre-compression multipart blob storage objects could corrupt byte ranges for other traces in the same object, causing 416 errors when reading their payloads.
  * Fixed crash when viewing a tool run in an in-progress trace.
  * Lowered Insights job schedule minimum interval from 6 hours to 1 hour, configurable via `CLIO_SCHEDULE_MIN_INTERVAL_SECONDS` environment variable.
  * LLM auth proxy now supports Insights (CLIO) service identity for JWT-based LLM authentication.
  * Fixed subagent files not being deleted from hub repo memory when subagents are removed in the agent editor.
  * Simplified Arcade workspace connection status to show "Workspace configured" instead of the confusing "Connected account" label with a redundant badge.
  * Fixed a bug where expanding a tool call in the run detail view and scrolling away caused it to collapse back when scrolled into view again.
  * Agent file reads (clone, inspect, startup) now correctly use the hub as the source of truth when hub memory is enabled.
  * Fixed custom output rendering (HTML charts via iframe) not working in the redesigned experiment detail panes.
  * Allowed usage of LLM Auth Proxy in self-hosted by default.
  * Sessions facets raw path now returns input/output KV facets when `RUNS_LITE_STATS_TENANTS` is enabled, matching the Python backend behavior.
  * Click-to-copy tooltips (e.g. project ID) now respond to clicks on the tooltip content itself, not just the trigger badge.
  * Improved MCP server authorization enforcement in the platform backend.
  * Added Baseten as a model provider with GLM-5 support.
  * Improved LLM inference efficiency by reducing date precision in system prompts from minute-level to date-only.
  * Fixed Polly losing trace context when a trace page is expanded to full page view.
  * Added a unified files sidebar to Fleet chat, accessible via a "Files" button in the header, to browse, search, create, rename, move, and preview all agent-generated files in one panel.
  * Added `SSRF_ALLOW_PRIVATE_IPS_WEBHOOKS`, `SSRF_ALLOW_PRIVATE_IPS_MCP_SERVERS`, and `SSRF_ALLOW_PRIVATE_IPS_TOOLS` environment variables to allow self-hosted deployments to connect to services on private IP ranges.
  * Added `get_current_time` tool to Polly so relative time expressions in filter queries resolve correctly.
  * Reference outputs are now always visible in the experiment trace detail view, fixing an issue where they were hidden for some organizations.
  * Fixed agent OAuth connections failing with "Unknown provider" errors for non-personal agents.
  * Added Base URL configuration support for Bedrock models in the playground and model configurations, enabling custom endpoint URLs for proxy or gateway deployments.
  * Added sign out button back to the settings page sidebar.
  * The run rules list endpoint now returns `backfill_id` when backfill progress is requested.
  * SSO users can no longer see or accept pending invites to organizations other than their own SSO organization.

  * Pairwise annotation queues now respect `reviewer_access_mode`: completion/archive logic gates on assigned reviewers only, and GET responses include `assigned_reviewers`.
  * Agent chat messages are no longer grouped into a collapsible "Completed N steps" container. A single copy dropdown on the last AI message of each turn lets you copy just the response or all steps including tool outputs.
  * Fixed pagination in the waterfall view for thread traces, where threads with more than 20 turns now load additional traces when scrolling.
  * Fixed "Empty Message" text appearing in the agent editor chat when AI invokes tools without accompanying text.
  * Added Salesforce SOQL query tool to Fleet, enabling agents to query Salesforce data via OAuth.
  * Annotation queue run list items now show reviewer names and avatars when hovering over the review stats badge.
