 # Changelog
 
 ## master / unreleased
+  **This release removes support for chunks storage. See below for more.**
+* [CHANGE] Remove support for chunks storage entirely. If you are using chunks storage on a previous version, you must [migrate your data](https://github.com/cortexproject/cortex/blob/v1.11.1/docs/blocks-storage/migrate-from-chunks-to-blocks.md) 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.
 * [ENHANCEMENT] Querier/Ruler: Retry store-gateway in case of unexpected failure, instead of failing the query. #4532
 * [ENHANCEMENT] Ring: DoBatch prioritize 4xx errors when failing. #4783
 * [FEATURE] Compactor: Added `-compactor.block-files-concurrency` allowing to configure number of go routines for download/upload block files during compaction. #4784
 * [FEATURE] Compactor: Added -compactor.blocks-fetch-concurrency` allowing to configure number of go routines for blocks during compaction. #4787
 * [FEATURE] Compactor: Added configurations for Azure MSI in blocks-storage, ruler-storage and alertmanager-storage. #4818
 * [BUGFIX] Memberlist: Add join with no retrying when starting service. #4804
 
-
-
 ## 1.13.0 2022-07-14
 
 * [CHANGE] Changed default for `-ingester.min-ready-duration` from 1 minute to 15 seconds. #4539
