+- Cleaned up some configuration options in preparation for the Cortex `1.0.0` release (see also the [annotated config file breaking changes](#annotated-config-file-breaking-changes) below):
   - Removed CLI flags support to configure the schema (see [how to migrate from flags to schema file](https://cortexmetrics.io/docs/configuration/schema-configuration/#migrating-from-flags-to-schema-file))
   - Renamed CLI flag `-config-yaml` to `-schema-config-file`
   - Removed CLI flag `-store.min-chunk-age` in favor of `-querier.query-store-after`. The corresponding YAML config option `ingestermaxquerylookback` has been renamed to [`query_ingesters_within`](https://cortexmetrics.io/docs/configuration/configuration-file/#querier-config)

 ### Full changelog
 
 * [CHANGE] Removed support for flags to configure schema. Further, the flag for specifying the config file (`-config-yaml`) has been deprecated. Please use `-schema-config-file`. See the [Schema Configuration documentation](https://cortexmetrics.io/docs/configuration/schema-configuration/) for more details on how to configure the schema using the YAML file. #2221
-* [CHANGE] Config file changed to remove top level `config_store` field in favor of a nested `configdb` field. #2125
+* [CHANGE] In the config file, the root level `config_store` config option has been moved to `alertmanager` > `store` > `configdb`. #2125
 * [CHANGE] Removed unnecessary `frontend.cache-split-interval` in favor of `querier.split-queries-by-interval` both to reduce configuration complexity and guarantee alignment of these two configs. Starting from now, `-querier.cache-results` may only be enabled in conjunction with `-querier.split-queries-by-interval` (previously the cache interval default was `24h` so if you want to preserve the same behaviour you should set `-querier.split-queries-by-interval=24h`). #2040

 Cortex 0.6.0 is the last version that can *read* denormalised tokens. Starting with Cortex 0.7.0 only normalised tokens are supported, and ingesters writing denormalised tokens to the ring (running Cortex 0.4.0 or earlier with `-ingester.normalise-tokens=false`) are ignored by distributors. Such ingesters should either switch to using normalised tokens, or be upgraded to Cortex 0.5.0 or later.
 
+### Known issues
+
+- The gRPC streaming for ingesters doesn't work when using the experimental TSDB blocks storage. Please do not enable `-querier.ingester-streaming` if you're using the TSDB blocks storage. If you want to enable it, you can build Cortex from `master` given the issue has been fixed after Cortex `0.7` branch has been cut and the fix wasn't included in the `0.7` because related to an experimental feature.
