Minor Changes

• #588 ba9efc5 Thanks @sameelarif! - Added support for offloading agent tasks to the API.

• #600 11e015d Thanks @sameelarif! - Added a stagehand.history array which stores an array of act, extract, observe, and goto calls made. Since this history array is stored on the StagehandPage level, it will capture methods even if indirectly called by an agent.

• #601 1d22604 Thanks @seanmcguire12! - add custom error classes

• #599 75d8fb3 Thanks @miguelg719! - cleaner logging with pino

• #609 c92295d Thanks @kamath! - Removed deprecated fields and methods from Stagehand constructor and added cdpUrl to localBrowserLaunchOptions for custom CDP URLs support.

• #571 73d6736 Thanks @miguelg719! - You can now use Computer Using Agents (CUA) natively in Stagehand for both Anthropic and OpenAI models! This unlocks a brand new frontier of applications for Stagehand users 🤘

• #619 7b0b996 Thanks @sameelarif! - add disablePino flag to stagehand constructor params

• #620 566e587 Thanks @kamath! - You can now pass in an OpenAI instance as an llmClient to the Stagehand constructor! This allows you to use Stagehand with any OpenAI-compatible model, like Ollama, Gemini, etc., as well as OpenAI wrappers like Braintrust.

• #586 c57dc19 Thanks @sameelarif! - Added native Stagehand agentic loop functionality. This allows you to build agentic workflows with a single prompt without using a computer-use model. To try it out, create a stagehand.agent without passing in a provider.
