🦅 Loki 2.7.0 🦅

This is release v2.7.0 of Loki.

Notable changes:

• New Internal Server and TLS TLS can now be configured everywhere and there is an internal server to allow ring, memberlist, and readiness handlers to continue to work without TLS.
• Better Support for Azure Blob Storage thanks to the ability to use Azure's Service Principal Credentials.
• Logs can now be pushed from the Loki canary so you don't have to rely on a scraping service to use the canary.
• Additional label_format fields __timestamp__ and __line__.
• New embedded cache which is an in-process cache system that runs loki without the need for an external cache (like memcached, redis, etc).
• New HTTP endpoint for Ingester shutdown that will also delete the ring token.
• Faster label queries thanks to new parallization.
• Introducing Stream Sharding an experimental new feature to help deal with very large streams.
• Promtail
  • support for max stream limit
  • config reload endpoint / signal
  • compressed file support
  • lambda-promtail now supports Kinesis data stream events
  • matches for the journal reader
  • basic tracing support
