Loki 3.0.0

Grafana Labs and the Loki team are excited to announce the release of Loki 3.0. Here's a summary of new enhancements and important fixes.

For a full list of all changes and fixes, refer to the CHANGELOG.

Features and enhancements

Key features in Loki 3.0.0 include the following:

• Query acceleration with Bloom filters (experimental): This is designed to speed up filter queries, with best results for queries that are looking for a specific text string like an error message or UUID.

• Native OTel Support: A simplified ingestion pipeline (Loki Exporter no longer needed) and a more intuitive query experience for OTel logs.

• Helm charts: A major upgrade to the Loki helm chart introduces support for Distributed mode (microservices), includes memcached by default, and includes several updates to configurations to improve Loki operations.

• Lambda/Promtail: support dropping labels (#10755) (ec54c72).

• Docs improvements: All the Getting Started topics have been revised, including a new Quickstart to help new users get up and running with Loki faster.The Storage, Configuration Reference, and API documentation have been updated to reflect deprecated and removed code, configuration options, and API endpoints.

Deprecations

One of the focuses of Loki 3.0 was cleaning up unused code and old features that had been previously deprecated but not removed. Loki 3.0 removes a number of previous deprecations and introduces some new deprecations. Some of the main areas with changes include:

• Deprecated storage options including the deprecation of the BoltDB store.

• Deprecated configuration options.

• API endpoint deprecations.

To learn more about breaking changes in this release, refer to the Upgrade guide.

Upgrade Considerations

The path from 2.9 to 3.0 includes several breaking changes. For important upgrade guideance, refer to the Upgrade Guide and the separate Helm Upgrade Guide.
