0.71.x

  7 minute read  

With W&B Server 0.71, Registry is turned on by default for all organizations. For more details about the staged Registry rollout, see the relevant note in Features. This release brings several improvements and fixes to workspaces: Keep media panels with a common step slider in sync, navigate through through full-screen panels more efficiently, and find more details about a run’s total duration and time actively running. in the Run Overview page. Automations have been enhanced, and you can now trigger an automation based on an artifact version’s tags.

Support and end of life

• W&B Server v0.57 and below reached end of life on July 29, 2025.

A W&B Server release is supported for 12 months from its initial release date. As a reminder, customers using Self-managed are responsible to upgrade to a supported release in time to maintain support.

Refer to Release policies and processes. For assistance or questions, contact support.

Upcoming changes

• We’re optimizing our rendering behavior in the workspace to provide faster loading in workspaces with many panels, as well as more responsive and accurate drag-and-drop of panels in workspaces. As part of this, we plan to remove the “Custom grid” layout in workspace sections in the next (0.72) release. Custom grids will remain available in Reports. Reach out to your W&B team or support for any questions or concerns.
• In an upcoming release, we will align multi-run and single-run workspace views, so when you drill into a single run, you’ll see the same layout and configuration of panels as you’ve configured for the multi-run view, including any custom charts, layouts, and settings. The goal is help you stay in context and avoid re-work around configuring your views. However, this will remove the ability to customize unique single-run views, isolated from the rest of the workspace. Reach out to your W&B team or support for any questions about the migration.
• Over the next several releases, we will continue migrating existing team-level Model Registry to W&B Registry, For details and a reminder about the timeline, see the W&B Registry GA announcement below.

Features

• We’re migrating existing team-level Model Registry to W&B Registry in stages over the next several releases. No action is needed on your end; W&B will automatically copy Model Registry assets for each team to a corresponding automatically-created team-level private registry.  Existing references to model collections in your old team-level Model Registry will still work.

  1. In Server v0.71 (this release), Registry is now turned on by default for all organizations.
  2. Server v0.72 (August) will include an opt-out environment variable that will execute this migration automatically during the upgrade. Migration takes between 5 and 30 minutes for most organizations. During the migration, linking artifacts to either the old team’s Model Registry or the new Registry will fail with an error. Artifact logging and retrieval will not be affected.
  3. In Server v0.73 (September), we will remove this flag and migration will happen during the upgrade.

  We’re optimizing for a seamless, minimally-inconveniencing upgrade to a powerful new experience. Reach out to your W&B for any questions about the migration.

• An automation can now be triggered by adding a tag to an artifact. See Artifact events.

• When viewing a panel in full screen, view the next or previous panel in the section using the Previous and Next buttons or the left and right arrow keys.

• When viewing a media panel in full screen, move the step slider with CMD + left or right arrow keys (macOS) or Ctrl + left or right arrow keys (Windows / Linux).

• You can now synchronize media panels with the same step slider key so that when you advance the step slider in one media panel, the step sliders for other panels also advance. Open the workspace or section settings, go to Media, click the Sync tab, then turn on Sync slider by key (Step).

• The Run Comparer includes a new Meta section with metadata about the run, such as the command, Python version, and GPU type.

Weave

• The Trace plots tool allows you to explore, visualize, and debug trace-level metrics like latency, cost, or tokens over time using custom interactive charts. Learn more.
• Online Evaluations: Monitor your traces in Dedicated Cloud by attaching Monitors to your incoming traces. Monitors run in the background as LLM judges and score a subset of calls that you specify. Use Monitors to track production behavior, catch regressions, collect real-world production data, and more. Learn more.
• Added AutoGen and LlamaIndex integrations. AutoGen is a framework from Microsoft for building AI agents and applications, with components for conversational AI, core multi-agent functionalities, and integrations with external services, and tools for no-code agent prototyping. LlamaIndex is a powerful framework for building LLM-driven applications like RAG systems, chatbots, and agents.
• Improved Integrations with OpenAI, LangChain, ChromaDB, Verdict, including:
  • Document view for Langchain and ChromaDB.
  • Chat view rendering for LangChain.
  • A new export format for OpenAI.
• Added new hosted open weight models for W&B Inference:
  • Qwen3-235B-A22B-Thinking-2507
  • Qwen/Qwen3-Coder-480B-A35B-Instruct
  • Qwen/Qwen3-235B-A22B-Instruct-2507
  • Kimi-K2-Instruct
• Added support to the TypeScript SDK for creating and publishing prompts. Learn more.
• The new Content class allows you safely to upload data of any MIME type, with automatic Base-64 encoding, automatic metadata extraction, and more.

Fixes

• A run’s Overview page now displays the run’s uptime and tracked hours. A run’s uptime represents the run’s total duration from start to finish, while the run’s tracked hours represent the duration of time that the run was actively running experiments or computations.
• When you zoom into a line plot, then open it in full screen mode, the full screen plot now correctly maintains the same zoomed-in view.
• Fixed a bug where updating the number of groups shown in a plot did not update the plot.
• When Show Original is selected in line plots, the original unsmoothed line is now dimmer than the smoothed line.
• Full fidelity line plots now show the number of runs in the plot.
• Fixed a bug that could unexpectedly convert a plot that is explicitly set to a line plot to a bar plot when only one value is present per run.
• X-axis expressions now support nested config fields.
• The Registry link has been removed from the sidebar on the Artifacts page. To access Registry, click Home, then click Registry.
• Line plots in a workspace or section can optionally show the bin range in the tooltip when you hover over a point. Open the workspace or section settings, click Line plots, go to the Display preferences tab, then turn on Show bin range in tooltip.
• Fixed a bug when clicking a link in the Registry artifact lineage page would update the URL and parameters in the browser but not update the page contents. The UI now updates when the URL changes.
• Fixed a bug in Registry where collection tables were sorted as strings instead of floats.
• Fixed a bug in Registry where the lineage info drawer would always show the latest version for the selected artifact, even when a different version was selected.
• Fixed a mobile display bug where the panel search bar was missing.
• When you sort the run selector by any attribute with coloring by key on, the top runs in the plot are now colored correctly.
• When using grouped runs, parallel coordinate plots now correctly show the group name.
• State is now correctly shown by default in the Sweeps table.
• Sweeps now show correctly when grouping by custom display names.
• Fixed wrapping of long names for Sweeps and Reports.
• Improved the copy and paste behavior for console logs. Line numbers are no longer copied, and timestamps now appear inline instead of on a new line.
