2026-09-21-openhands-v1-15-0-removes-the-pdf-preview-sandbox-tagged
v1.15.0 removes the PDF preview sandbox (tagged). The iframe for PDF preview in Files/Preview lost sandbox="allow-same-origin", because Chromium’s built-in PDF viewer will not run in a sandboxed frame. PDFs render now. The frame that shows files from the agent workspace is no longer sandboxed.
Channel: tagged-release (was main-unreleased in the parent). Half: both. Date: 2026-08-21.
Operator consequence: On v1.15.0 and later, treat opening a file the agent produced in preview as opening it in your browser. For untrusted repos, download and inspect the file instead of previewing it in Canvas.
