🎆🎁Happy Holidays from the Loki team!🎁🎆

Please enjoy Loki 2.1.0 to welcome in the New Year!

This release contains a number of fixes, performance improvements and enhancements to the 2.0.0 release!

Notable changes

Helm users read this!

The Helm charts have moved!

  • 2720 torstenwalter: Deprecate Charts as they have been moved

This was done to consolidate Grafana's helm charts for all Grafana projects in one place: https://github.com/grafana/helm-charts/

From now moving forward, please use the new Helm repo url: https://grafana.github.io/helm-charts

The charts in the Loki repo will soon be removed so please update your Helm repo to the new URL and submit your PR's over there as well

Special thanks to @torstenwalter, @unguiculus, and @scottrigby for their initiative and amazing work to make this happen!

Also go check out the microservices helm chart contributed by @unguiculus in the new repo!

Fluent bit plugin users read this!

Fluent bit officially supports Loki as an output plugin now! WoooHOOO!

However this created a naming conflict with our existing output plugin (the new native output uses the name loki) so we have renamed our plugin.

  • 2974 hedss: fluent-bit: Rename Fluent Bit plugin output name.

In time our plan is to deprecate and eliminate our output plugin in favor of the native Loki support. However until then you can continue using the plugin with the following change:

Old:

[Output]
    Name loki

New:

[Output]
    Name grafana-loki
