Features and enhancements

-
Helm charts: A major upgrade to the Loki helm chart introduces support for
Distributedmode (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.
