 We've added two new features to the [Deployments API preview][deployments-preview]: the ability to query deployments and a new `task` attribute for different types of deployment tasks.

 You can now search for deployments via query parameters to the [listing endpoint][listing-endpoint]. You can filter on `sha`, `ref`, `task`, and `environment`. This makes it easier to answer questions like "when was the last time someone deployed to staging?"

 We've also added a `task` attribute to the deployments model. The `task` attribute exists to allow you to specify tasks other than just pushing code. Popular deployment tools like [capistrano][capistrano] and [fabric][fabric] support named tasks to do things like run schema migrations. We hope this attribute will give integrators the flexibility they need to provide custom functionality.
