:eagle: Loki 2.7.0 :eagle:

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
