This release contains a slew of bug fixes, doc improvements, and feature enhancements, but some of our favourite highlights include...

- A new shard stats telemetry device was added that records shard allocations and statistics as well as segment counts - [https://github.com/elastic/rally/pull/1258](https://github.com/elastic/rally/pull/1258)
- Users can now specify a gradual ramp up of client counts via the `ramp-up-time-period` task property. This avoids initial spikes in load when high client counts are in use - [https://github.com/elastic/rally/pull/1266](https://github.com/elastic/rally/pull/1266)
- Amazon S3 support is now optional instead of a requirement, meaning that the `boto3` SDK is no longer installed by default. If S3 support is required it can be installed via running `python -m pip install esrally[s3]` instead of `python -m pip install esrally` - [https://github.com/elastic/rally/pull/1252](https://github.com/elastic/rally/pull/1252)
- Rally is now more lenient when detecting whether a cluster was in use prior to a benchmark running. This results in less spurious warnings at benchmark startup - [https://github.com/elastic/rally/pull/1256](https://github.com/elastic/rally/pull/1256)
- The `relative-time` property (in ms) was reintroduced for metrics documents in preparation for the removal of the `relative-time-ms` field in Rally 2.3.0 - [https://github.com/elastic/rally/pull/1273](https://github.com/elastic/rally/pull/1273)
