 2. Also removes the `query_timeout` from the querier YAML section. Instead of configuring `query_timeout` under `querier`, you now configure it in [Limits Config](/docs/loki/latest/configuration/#limits_config).
 3. `s3.sse-encryption` is removed. AWS now defaults encryption of all buckets to SSE-S3. Use `sse.type` to set SSE type. 
 4. `ruler.wal-cleaer.period` is removed. Use `ruler.wal-cleaner.period` instead.
