We have just released Rally 0.5.3. This is a maintenance release that fixes a couple of bugs but also brings a few new features.

## How to...?

- ... upgrade: `pip3 install --upgrade esrally`
- ... install: `pip3 install esrally`

Note: Depending on your system setup you probably need to prepend these commands with `sudo`.

Please follow the [quickstart](https://esrally.readthedocs.io/en/stable/quickstart.html) for a first time install though.

## Release Highlights

With [#251](https://github.com/elastic/rally/issues/251) we expose a new property [schedule](http://esrally.readthedocs.io/en/stable/track.html#schedule) for operations. Before 0.5.3, Rally scheduled each operation using a deterministic distribution. Now you can choose between deterministic (default) or a Poisson distribution or even [plug in your own custom schedule](http://esrally.readthedocs.io/en/stable/adding_tracks.html#custom-schedulers). The diagram below shows how Rally will schedule operations according to each distribution. Both schedules will achieve an average throughput of 1 operation per second (over a long-enough time period):

Also many thanks to @Keyur_Doshi who added the ability to [save tournament reports](https://github.com/elastic/rally/issues/249).

See the [full list of changes on the 0.5.3 release page](https://github.com/elastic/rally/releases/tag/0.5.3).

All users are recommended to upgrade to this version.
