Cursor 3.5.17 removed Keep/Undo and applies Agent changes directly

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

After updating to Cursor 3.5.17, the Agent now applies changes directly to files without showing the previous review workflow.

Keep / Undo controls are gone.

Settings referenced in Cursor documentation and forum posts (Inline Diffs, Applying Changes, Review Control Location) do not exist in my installation and cannot be found through Settings search.

This change happened immediately after the update and changed my workflow completely.

Steps to Reproduce

  1. Update Cursor to version 3.5.17.
  2. Open any project.
  3. Ask Agent to modify a file.
  4. Agent writes changes directly to the file.
  5. No Keep / Undo review step is shown.
  6. Search Settings for:
    • Inline Diffs
    • Applying Changes
    • Review Control Location
  7. No matching settings are available.

Operating System

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

This issue is still present in Cursor 3.5.17 (2026-05-20).
I do not have Inline Diffs, Applying Changes, Review Control Location, or Keep/Undo available in Settings.
Agent applies file changes directly.

Hey, common question after the update. In the popup it’s called Auto Keep, but in settings it’s Inline Diffs, so that’s where the confusion comes from. If you search in the standard VS Code Settings, you won’t find it. These options are only in Cursor Settings.

What to do:

  • Open Cursor Settings (not VS Code Settings): Ctrl+Shift+J or Cmd+,
  • Go to Agents > Applying Changes
  • Turn on Inline Diffs

If Keep or Undo still don’t show up, turn Inline Diffs off, turn it back on, and restart Cursor.

Let me know if it still doesn’t help.
