Grok Build 1.0.38

1.0.37→1.0.38·September 19, 2026 at 1:36 AM UTC

Patch release 1.0.38: more reliable image chips in the composer, and enforced hooks from signed deployment requirements.toml.

Changelog

  • [fix] Image chips in the prompt buffer stay attached when [Image #N] comes back as plain text (for example via Ctrl+K then Ctrl+Y, undo, or a plain-text paste), as long as the composer still holds the image. If the image is gone, the placeholder is sent as text and a toast explains why.
  • [changed] Hooks from the signed $GROK_HOME/requirements.toml written by deployment sync are enforced the same way as root-owned system layers: they cannot be turned off from the hooks modal, enable/disable APIs, or disabled-hooks, and a lower-layer copy cannot take over their provenance while the file still matches the server-signed envelope. An edited copy, or one whose signature is missing or unreadable, is treated as the user’s own file again (requirements/user:); an unreadable requirements.toml contributes no hooks. Pairing this with fail_closed = true refuses the session on tampering (an unreadable file is still a read error and does not block startup).
  • [changed] Keyboard-shortcuts docs updated to describe the image-chip re-attach and toast behavior.

Under the hood

  • Prompt-widget image state handling tightened so chip re-attachment and missing-image placeholders behave consistently.
  • Worktree seed support extended in the shell layer.
  • Startup telemetry refined with finer spans for frame gaps, slow phases, and token accounting.

Upgrade notes

  • Deployments that ship a signed $GROK_HOME/requirements.toml should keep the signature file readable alongside it. With fail_closed = true, editing the signed file or dropping its signature will refuse the session until the signed envelope is restored.
