We have just released Rally 0.5.1. With this release we show request error rates during benchmarks in the summary report (see [#234](https://github.com/elastic/rally/issues/234)).

## 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.

## Changes

We now show request error rates during benchmarks in the summary report (see [#234](https://github.com/elastic/rally/issues/234)). Rally gathers this metric for quite some time now but you'd need to extract it yourself from the metrics store.

Here is an example of the new output (it's the last line in the example):

```auto
| All | Min Throughput | index-append | 661.248 | docs/s |
| All | Median Throughput | index-append | 661.248 | docs/s |
| All | Max Throughput | index-append | 661.248 | docs/s |
| All | 50.0th percentile latency | index-append | 375.935 | ms |
| All | 100.0th percentile latency | index-append | 378.297 | ms |
| All | 50.0th percentile service time | index-append | 375.935 | ms |
| All | 100.0th percentile service time | index-append | 378.297 | ms |
| All | error rate | index-append | 0 | % |

```

All users are recommended to upgrade to this version.
