Trace Explorer Release notes

Version 1.3.0 - Feb 10th 2026

New Features

  • Revamped UI & UX: Cleaner visuals, refined layouts, and smoother interactions across the board for a more intuitive experience.

  • Content-first exploration: The interface now revolves around node content with simplified navigation and clearer visual hierarchy, making it easier to browse and discover nodes.

  • User settings: You can now customize your theme and default views to suit your preferences.

Version 1.2.1 - Oct 17th 2025

Bug Fix

  • Restored scroll bars in JSON view: The scroll bars are now correctly displayed in the exploration panel when viewing in JSON format.

Version 1.2.0 - Oct 14th 2025

New Features

  • Formatted panel in the node explorer: The formatted panel is now the default view. If this panel is empty, the JSON panel will automatically be displayed instead.

  • Markdown & JSON formatting: Inputs and outputs in Markdown and JSON formats are now rendered correctly.

  • Improved tool call display: Tool calls and their corresponding outputs are now displayed in a more readable format, even when streamed.

  • Copy to clipboard: You can now copy the content of any text-based inputs or outputs directly to your clipboard.

  • Collapsible conversations: Individual turns within a conversation trace can now be expanded and collapsed, making it easier to navigate long exchanges.

  • Search in selected nodes: A search bar has been added to the node explorer, allowing you to find specific text within the currently selected node.

  • Quick navigation: When the node explorer is in full-screen mode, you can now use quick navigation tools to help you navigate to the next available non-empty child or parent node.

  • Tokens, cost and time per node: The node explorer now displays key metrics for each node:

    • Time: Duration, and start and end times of the selected node.

    • Token counts: Prompt, completion and total counts.

    • Estimated cost: A cost estimation for the selected node.

  • Accessibility Improvements: To make node types easier to distinguish, the first letter of the node type is now displayed in the tree view and quick navigation menu.

  • Handling of empty nodes: Nodes without any data are now visually distinct. To streamline navigation, these empty nodes no longer open the node explorer, helping you focus on relevant data.

  • Responsive full-screen view: In full-screen mode, the node explorer’s panels are now arranged vertically for a better viewing experience. In the standard view, they are arranged horizontally.

  • Trace detail panel repositioned: The trace detail panel is now displayed on the right by default, preventing it from obscuring underlying graphs.

  • Copy whole trace to clipboard: This feature allows users to copy the currently selected trace to the clipboard.

Version 1.1.0 - Jun 20th 2025

New Features

  • Expand all/collapse: Expand all/collapse call buttons have been added to the trace explorer while in the tree view tab.

  • Reset view button: The reset view button now resets filters as well as the view in both the tree and timeline tabs.

  • New components: The user interface was updated to use components with a similar look and feel as those in Answers and Agent Connect.

Bug Fix

  • Date selection: It was previously possible to have two date ranges selected at the same time in the date range selector. This is no longer possible.

  • Reload button: When reloading the traces list, traces were previously reset in the traces view but not in the trace history list. Both are now reset.

  • Tab selection: The trace history list bars on the left and right appeared black when a tab was selected. They are no longer black.

  • Node panel: Previously, when inspecting a node, the inspect panel would reappear (even after closing) if you went through an “empty view”. This no longer happens.

Version 1.0.5 - Jul 4th 2025

Bug Fix

  • Traces list: Fixed multiple bugs affecting the listing of the traces in the left panel.

Version 1.0.4 - Jun 27th 2025

New Features

  • Explore trace: A trace is now automatically retrieved from local storage when a user is redirected to a trace explorer webapp using the “Explore trace” button.

Bug Fix

  • Misc: Fixed various bugs related to the UI (mostly in the Timeline view).

Version 1.0.3 - Jun 13th 2025

Bug Fix

  • Remove hardcoded ``pandas`` / ``numpy`` versions: To avoid build errors for older code-env configurations, these versions have been removed so DSS can decide which versions to use.

Version 1.0.2 - Jun 9th 2025

New Features

  • Dataset setting is optional: When installing the plugin, choosing a dataset to get traces from is no longer mandatory.

Bug Fix

  • Unique “pasted trace” key: Each Trace Explorer webapp now has its own local storage key to avoid overriding pasted traces from other webapps.

Miscellaneous

  • Code-env core packages.

  • Maintenance: Updated dependency versions to avoid security issues.

  • Build: webaiku dependency has been removed.
