Today we're pleased to announce Rally 0.2.1.

# How to...?

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

Please follow the [installation instructions](https://esrally.readthedocs.io/en/latest/#first-time-setup) for a first time install though.

# Release Highlights

## Tournament Mode

Rally now has a tournament mode which allows you to compare performance across races

Run `esrally list races` to find previously recorded races. Then compare races by their race timestamp, e.g. `esrally compare --baseline=20160502T190127Z --contender=20160502T191011Z`. See the [docs on tournament mode](https://esrally.readthedocs.io/en/latest/tournament.html) for more details.

Be aware that the tournament mode is not yet ideal as there is natural variance across races. Therefore, we will [run multiple rounds in each race](https://github.com/elastic/rally/issues/92) with the next release to account for this variance.

## User Defined Tags

Rally can now add one user-defined tag to each metrics record captured during a race. This can be used to split data in Kibana or to memorize what a race was about when running `esrally list races`. Just specify the tag on the command line with `--user-tag`, e.g. `--user-tag=baseline_github_ticket_1234`.

## perf Profiler

On Linux, Rally can now use the perf profiler to gather CPU performance counters. Data is written into a separate log file after each race. See the [docs](https://esrally.readthedocs.io/en/latest/telemetry.html#perf) for more details.

## New tracks

We have added a track (benchmark data file) consisting of half a million academic papers (under the CC license) to benchmark a fulltext scenario. You can run it with `esrally --track=pmc` but keep in mind the benchmark data are 6GB (compressed). In total you need roughly 70GB of free disk space to run this track.

We also added a track to benchmark geo queries in Elasticsearch which you can run with `esrally --track=geopoint`. This track needs about 7GB of free disk space.

# Contributions

- Kudos to Lyndon Swan for adding support for additional compression formats in Rally: [https://github.com/elastic/rally/pull/88](https://github.com/elastic/rally/pull/88)
