v6.0.0

What's Changed

• Update readme by @NelsonVides in #189
• Summary sketch by @NelsonVides in #177
  • BREAKING: Quantile summaries now use the DDSketch algorithm under the hood, which is mergeable and offers much more accuracy and correctness. However, it is configured differently and some configuration keys might clash. It is compatible with the defaults but if you had any custom configurations you'll need to double-check:
    • Removes: targets and compress_limit are now meaningless.
    • Adds: error and bound as in https://hexdocs.pm/ddskerl/ddskerl_ets.html#t:opts/0
• Run promtool in CI by @NelsonVides in #188
  • BREAKING: Default system metrics were not compliant with Prometheus/OpenMetrics 1.0 naming conventions. promtool has been added to CI and violating metrics have been renamed. If you need backwards compatibility you can enable prometheus_collectors_compat by adding {prometheus, [{collectors_compat, true}]} to your config.
