Full changelog

What's New

New Tools

browser_find — Search the accessibility snapshot of the current page for text or a regular expression. Returns matching snapshot nodes with a few lines of surrounding context (like search snippets), which is cheaper than capturing the whole snapshot when you only need to locate an element and its ref (#41605, #41654)

Tool Improvements

Less verbose snapshots — Accessibility snapshots are distilled to reduce noise and token usage (#41604)
Mobile & device emulation — New --mobile flag and --device option to emulate mobile devices from the CLI (#41657)
Navigation status — browser_navigate now surfaces non-2xx navigation status codes (#41589)

Bug Fixes

browser_navigate no longer crashes the response when navigation closes the last tab (e.g. privileged pages like chrome://) (#41675)
Await page initialization before taking a screenshot immediately after opening (#41646)
Enable the chromium sandbox for the default browser (#41652)
Preserve the configured output directory for additional tab videos (#41680)
Always pass noDefaults for CDP connections so attaching no longer applies unwanted default context options (#41676)
Close the isolated HTTP client context on disconnect (#41560)
Wait for the client event stream before sending server→client requests (#41559)
