  5 minute read  

W&B v0.73 marks a significant milestone in the migration to W&B Registry from team-level Model Registry; most organizations will be migrated automatically during the upgrade. UI improvements include colorblind-safe run color palettes, continuous color options metric-based run coloring, and smoother panel reorganization. This release also provides service principal authentication for BYOB (Bring Your Own Bucket) setups with CoreWeave AI Object Storage, along with improved console log handling and additional enhancements.

Support and end of life

• W&B Server v0.58 and below reached end of life on September 3, 2025.
• W&B Server v0.60 is scheduled to reach end of life in late September 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

• 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. Server v0.73 (this release) includes an opt-out environment variable that will migrate the team’s Model Registry automatically during the upgrade. Migration takes between 5 and 30 minutes for most organizations. During the migration, linking artifacts to either the old Model Registry or the new Registry will fail with an error. Artifact logging and retrieval will not be affected.
  2. In Server v0.74 (end of September), we will remove the opt-out flag and migration will happen during the upgrade.

  We’re optimizing for a seamless upgrade to a powerful new experience. Contact your W&B account team or support if you have any questions about the migration.

• Added a copy button to the Run Logs console page and improved paste behavior.

• W&B now offers two new colorblind-safe color palettes for runs. Set these in the Runs section of the Workspace settings.

• When coloring runs by metrics or numeric configs, you can now choose from five new continuous color palettes.

• During a W&B run, CoreWeave Mission Control monitors your compute infrastructure. This integration is now available on Dedicated Cloud.

• BYOB with CoreWeave AI Object Storage now supports authentication with service principals in Multi-tenant Cloud, Dedicated Cloud, and Self-Managed deployments. This helps you to avoid using static credentials in your deployment. Learn more at Bring your own bucket (BYOB).

Weave

• You can now group sessions or conversations across multiple traces with Weave Threads.
• The Trace view’s new Graph view visualizes the call tree structure as a graph.
• The Trace view includes new specialized views for documents retrieved with ChromaDB and Langchain improves handling of schemas such as chats. In Trace view, click a document to open its detailed view in a drawer to the right. Learn more at Navigate the trace view.
• You can now attach HTML to a trace as a media type.
• From the Assets tab, you can now create and edit prompts. Click Assets, then in the navigation, click Prompts. Click New prompt or click the name of an existing prompt to view its details. From there, click the pencil icon to edit and republish the prompt.
