Grok Build 1.0.20

1.0.19→1.0.20·September 4, 2026 at 6:37 PM UTC

Patch release: renames the harness upload wait setting and tightens how turn-end trace uploads are drained, especially for headless runs.

Changelog

  • [changed] Replaced harness.block_for_upload with harness.wait_for_uploads. When enabled, Grok waits for turn-end trace uploads before returning the prompt response. It is off by default.
  • [changed] One-shot headless runs now drain pending turn-end uploads on exit, using a mandatory minimum budget of about 150s (parse window plus one upload attempt). A larger upload_flush_timeout_secs extends that budget.
  • [changed] Config reference docs updated for the new harness upload-wait key and headless drain behavior.
  • [changed] Marketplace plugins pstack and stripe updated to newer upstream revisions.

Under the hood

  • Turn-end upload draining is handled more explicitly so interactive and headless exits can finish pending trace uploads cleanly.
  • Plugin marketplace install path reworked for more reliable plugin installation.
  • OpenTelemetry timeout handling refined.
  • Dock UI module layout reorganized.
  • Added XAI_EXPLORER_SERVICE_URL for explorer service configuration; removed the unused GROK_PLUGIN_DATAN flag.

Upgrade notes

  • If you set harness.block_for_upload in config, switch it to harness.wait_for_uploads. Behavior is opt-in for interactive turns; headless one-shot runs still flush uploads on exit under the timeout rules above.
