Loki 2.9.0

Grafana Labs is excited to announce the release of Loki 2.9. 🎉

Notable changes:

• Query Language Improvements: Several improvements to the query language that speed up line parsing and regex matching.
• Remote rule evaluation: Rule evaluation can now be handled by queriers to improve speed.
• Multi-store Index support: Loki now supports reading/writing indexes to multiple object stores which enables the use of different storage buckets across periods for storing index.
• New volume and volume_range endpoints: Two new endoints, index/volume and index/volume_range, have been added to Loki. They return aggregate volume information from the TSDB index for all streams matching a provided stream selector.
• New Storage Client: Add support for IBM cloud object storage as storage client.
• Block queries by hash: Queries can now be blocked by a query hash.
• logfmt stage improvements: logfmt parser now performs non-strict parsing by default which helps scan semi-structured log lines

For a full list of all changes please look at the CHANGELOG.

Loki 2.8.0

Grafana Labs is excited to announce the release of Loki 2.8. 🎉

Notable changes:

• TSDB index no longer experimental After extensive testing of the new TSDB index in our Grafana Cloud Logs offering, we can safely announce that it is no longer experimental and encourage all Loki deployments to use it!
• Query blocker Queries can now be blocked in the Querier/Ruler via a per-tenant runtime configuration.
• New backend target A new, third target was added to Loki's scalable configuration, which is the default configuration used in the Loki helm chart. This allows Loki to be run as 3 targets (read, write, and backend) and makes the read target stateless and therefore able to be run as a Kubernetes deployment that can be scaled automatically.
