 Major version upgrades listed here indicate that there is an incompatible breaking change needing manual actions.
 
+### Frome 0.79.x to 0.80.0
+This version allows setting a constant prefix for all created keys in Chunk storage(S3)
+```yaml
+loki:
+  storage_config:
+    object_prefix: loki-logs
+```
+
+Removed `store.max-look-back-period` flag. Use. Use `querier.max-query-lookback` config instead.
+
+Removed `ingester.max-transfer-retries` configuration option. The Write Ahead Log (WAL) supersedes the chunk transfer feature.
+
+Removed `shared_store` and `shared_store_key_prefix` from index shipper and compactor configs and their corresponding CLI flags. `object_store` setting in the `period_config` (which already configured the store for chunks) will be used to configure store for the index.
+
+And the newly added path_prefix option under the index key in period_config will configure the path under which index tables are stored.
+
+Deprecated `write_dedupe_cache_config` config section along with legacy index types (aws, aws-dynamo, bigtable, bigtable-hashed, cassandra, gcp, gcp-columnkey, grpc-store). Consider using TSDB index which does not require a write dedupe cache. 
+
+Refactored `default` block for `runtime_config`. The `default` block was removed and instead a top level config now exists in the standard Loki config called `operational_config`, you can set default values here for runtime configs.
+
 ### From 0.78.x to 0.79.0
 Removed the hardcoded, deprecated `boltdb.shipper.compactor.working-directory` flag in the Compactor Deployment template, so that it can be set with `.Values.compactor.extraArgs` and the `compactor.working-directory` flag if necessary.
