Support and end of life

  • W&B Server v0.67 has reached end of life.

The official list of supported and archived releases is on the docs site: Supported Server releases and Archived Server releases. 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.

Security

  • When creating a service account, you are now automatically guided to create an API key for it.
  • Confirmation is now required to delete a service account or an API key from the W&B App.
  • The backend now escapes column names in filters to help prevent SQL injection.
  • Email addresses that contain diacritical marks are now blocked from user registration or login.

Features

  • Pan and zoom on an image to inspect fine-grained image details directly in W&B's full-screen image modal. Open any image in full-screen, then:

    • Use UI controls or keyboard shortcuts to set your zoom level, reset to 100%, or zoom to fit.
    • Click and drag to pan when zoomed in.

  • For pinned and baseline runs, summary metric deltas show how each run compares to the baseline. To turn on semantic coloring for quick visual reference, you can set the Metric directionality for a column. This feature is now generally available.

  • You can now filter the run selector and Runs list by Git commit.
