Trace Explorer Release notes

Version 1.5.0 - Oct 13th, 2026

Compatible with DSS 13 and above.

New feature: Per-user trace storage

Traces are no longer shared across app users. Each user now has a dedicated subfolder in the storage folder and only sees their own traces.

Note

Previously saved traces will no longer be visible to all users. They are retained in the subfolder of the user who ran the application backend when they were created.

This feature does not restrict direct access to the underlying storage folder; users with folder permissions can still view all stored traces.

Trace management

  • Users can now import a trace directly from a JSON or TXT file and export a trace as a JSON file afterward.

  • Users can now rename traces that they imported into Trace Explorer.

Trace viewing

  • Improved display of node insights, including duration and estimated costs.

  • The JSON key-value viewer has been replaced by the raw JSON viewer wherever it was available to improve readability.

Trace processing

  • Traces containing nodes without begin, end, or timestamp values are now processed and imported correctly.

Miscellaneous

  • Links in Markdown components now open in a new tab.

  • Minor UI updates were made to elements, icons, spacing, and fonts.

Bug Fix

  • Improved traces browsing:

    • The trace list is now scrollable

    • The traces view has been updated with a tabbed layout for a more organized, user-friendly experience

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.

Bug Fix

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.
