In particular this includes:

- Filtering jobs by status
- Finding jobs by ID or name
- status as enum (better assurance of state)
- More fields on jobs (`duration`, `allowFailure`, timestamps)

An example query is:

```graphql
query($path: ID!, $name: String!) {
  project(fullPath: $path) {
    pipelines(first: 1) {
      nodes {
        jobs(statuses: [FAILED]) {
          nodes {
            name
            duration
            allowFailure
            queuedAt
            startedAt
          }
        }
        job(name: $name) {
          name
          status
        }
      }
    }
  }
}
```

Some CiJob fields are added, including CiJob.stage
Rather than a string, CiJob.stage is a full Stage object.
