v1.14.0

### Minor Changes

-   [#518](https://github.com/browserbase/stagehand/pull/518) [`516725f`](https://github.com/browserbase/stagehand/commit/516725fc1c5d12d22caac0078a118c77bfe033a8) Thanks [@sameelarif](https://github.com/sameelarif)! - `act()` can now use `observe()` under the hood, resulting in significant performance improvements. To opt-in to this change, set `slowDomBasedAct: false` in `ActOptions`.

-   [#483](https://github.com/browserbase/stagehand/pull/483) [`8c9445f`](https://github.com/browserbase/stagehand/commit/8c9445fde9724ae33eeeb1234fd5b9bbd418bfdb) Thanks [@seanmcguire12](https://github.com/seanmcguire12)! - When using `textExtract`, you can now do targetted extraction by passing an xpath string into extract via the `selector` parameter. This limits the dom processing step to a target element, reducing tokens and increasing speed. For example:

    ```typescript
    const weatherData = await stagehand.page.extract({
      instruction: "extract the weather data for Sun, Feb 23 at 11PM",
      schema: z.object({
        temperature: z.string(),
        weather_description: z.string(),
        wind: z.string(),
        humidity: z.string(),
        barometer: z.string(),
        visibility: z.string(),
      }),
      modelName,
      useTextExtract,
      selector: xpath, // xpath of the element to extract from
    });
    ```
