* Enable PromQL @ modifier with negative offset always
* Added configurations for Azure MSI in blocks-storage
* New limits (Querier/QueryFrontend)
* OpenTelemetry Bridge for Tracing

[CHANGE] Remove support for chunks storage entirely. If you are using chunks storage on a previous version, you must migrate your data on version 1.12 or earlier. Before upgrading to this release, you should also remove any deprecated chunks-related configuration, as this release will no longer accept that. The following flags are gone:
-dynamodb.*
-metrics.*
-s3.*
-azure.*
-bigtable.*
-gcs.*
-cassandra.*
-boltdb.*
-local.*
some -ingester flags:
- -ingester.wal-enabled
- -ingester.checkpoint-enabled
- -ingester.recover-from-wal
- -ingester.wal-dir
- -ingester.checkpoint-duration
- -ingester.flush-on-shutdown-with-wal-enabled
- -ingester.max-transfer-retries
- -ingester.max-samples-per-query
- -ingester.min-chunk-length
- -ingester.flush-period
- -ingester.retain-period
- -ingester.max-chunk-idle
- -ingester.max-stale-chunk-idle
- -ingester.flush-op-timeout
- -ingester.max-chunk-age
- -ingester.chunk-age-jitter
- -ingester.concurrent-flushes
- -ingester.spread-flushes
- -store.* except -store.engine and -store.max-query-length
- -store.query-chunk-limit was deprecated and replaced by -querier.max-fetched-chunks-per-query
-deletes.*
-grpc-store.*
-flusher.wal-dir, -flusher.concurrent-flushes, -flusher.flush-op-timeout
[CHANGE] Remove support for alertmanager and ruler legacy store configuration. Before upgrading, you need to convert your configuration to use the alertmanager-storage and ruler-storage configuration on the version that you're already running, then upgrade.
