July 2026

5 releases: 0.1.4 → 0.1.8

July brought significant quality-of-life improvements to Browser Harness, including built-in video recording of agent tasks, reduced Chrome permission prompts, and better Windows reliability. The month focused on making the tool faster to start and easier to use repeatedly.

Highlights

Browser Harness can now record agent work into short, verifiable videos with real browser actions and concise subtitles.
Chrome permission popups no longer appear for every task—connections now persist across a session.
Startup is faster by reusing existing tabs instead of opening new ones.
Windows support improved with UTF-8 logging, per-OS Chrome profile discovery, and clearer connection errors.
Telemetry now skips unnecessary pings when disabled and logs browser type for better diagnostics.

New

Video recording of browser tasks that condense hours of work with mistake-and-correction explanations and verified outcomes.
Built-in video creation with no separate skill or installation required.
Chrome permission acceptance persists across a session instead of prompting per task.
Reusable tab attachment (about:blank, New Tab, or existing chrome://inspect tab) for faster startup.
Cloud browser suggestion when no local browser is available.
Per-OS Chrome profile discovery on Windows, including Beta and Dev variants.

Improved

CLI telemetry is more robust: skips daemon ping when telemetry is off and logs browser type.
Recordings are off by default and can be enabled globally or per individual task.
Windows reliability improved with UTF-8 daemon logging and real startup tracebacks.
Remote debugging connection errors are clearer and more actionable.
Chrome://inspect is opened at most once every 3 minutes with guards against stale DevToolsActivePort files.
Only closes chrome://inspect tabs that Browser Harness itself opened, leaving user tabs untouched.
API key stdin example is now copy-pasteable.

Setup and permission errors now provide clearer, actionable guidance.
