    # ...
  end
end
```

After:

```ruby
class MyJob

    @arg2 = arg2
  end

  def call
    # ...
  end
end
```

* Use number of partitions of previous step for `jobs` option by default
* Changed `combine` to receive a `collector`
* Added mandatory `concurrency` argument to `load`

## v0.6.0

* Added `map_partitions`
* Added `combine`
* Added `dump` and `load`

## v0.5.0

* Added a `before` option to specify a callable to run before
  a step to e.g. populate caches upfront, etc.

## v0.4.0

* Pre-reduce in a map step when the subsequent step is a
  reduce step

## v0.3.0

* Changed partitioners to receive the number of partitions
  as second parameter

## v0.2.0
