### Minor Changes

-   [#588](https://github.com/browserbase/stagehand/pull/588) [`ba9efc5`](https://github.com/browserbase/stagehand/commit/ba9efc5580a536bc3c158e507a6c6695825c2834) Thanks [@sameelarif](https://github.com/sameelarif)! - Added support for offloading agent tasks to the API.

-   [#600](https://github.com/browserbase/stagehand/pull/600) [`11e015d`](https://github.com/browserbase/stagehand/commit/11e015daac56dc961b8c8d54ce360fd00d4fee38) Thanks [@sameelarif](https://github.com/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.
