## Body
Browserbase Stagehand releases published stagehand-python@4.2.0a0.dev1556: feat : expose timeout param in ts & protocol ( 3033). This automated release-watch entry was generated from the project's official GitHub release feed and is kept separate from human-reviewed editorial analysis. Release notes: why this PR adds the timeout param to the protocol, & exposes it publicly in ts. the default timeout is 20 seconds what changed added optional timeout settings to all 17 terminal locator methods, including reads. typescript callers can use click({ timeout: 5000 }) , fill("hello", { timeout: 5000 }) , or count({ timeout: 0 }) . started one deadline before frame resolution & passed it through the whole call. frame readiness, element lookup, typing delays, highlight duration, & extension-side upload preparation all share that budget. aligned typescript response waits with the execution timeout plus delivery grace. zero disables that response deadline too. long timeouts avoid the JS timer limit, & timeout errors retain their name & message. made the compatibility facade pass its remaining budget to native locator calls, including zero, instead of dropping timeout options test plan…
