 New options:
 
   New Store flags:
-  
+
     * `--store.grpc.series-sample-limit` limits the amount of samples that might be retrieved on a single Series() call. By default it is 0. Consider enabling it by setting it to more than 0 if you are running on limited resources.
     * `--store.grpc.series-max-concurrency` limits the number of concurrent Series() calls in Thanos Store. By default it is 20. Considering making it lower or bigger depending on the scale of your deployment.
 
   New Store metrics:
-  
+
     * `thanos_bucket_store_queries_dropped_total` shows how many queries were dropped due to the samples limit;
     * `thanos_bucket_store_queries_concurrent_max` is a constant metric which shows how many Series() calls can concurrently be executed by Thanos Store;
     * `thanos_bucket_store_queries_in_flight` shows how many queries are currently "in flight" i.e. they are being executed;
     * `thanos_bucket_store_gate_duration_seconds` shows how many seconds it took for queries to pass through the gate in both cases - when that fails and when it does not.

   New Store tracing span:
     * `store_query_gate_ismyturn` shows how long it took for a query to pass (or not) through the gate.

 - [#986](https://github.com/improbable-eng/thanos/pull/986) Allow to save some startup & sync time in store gateway as it is no longer needed to compute index-cache from block index on its own for larger blocks.
-  The store Gateway still can do it, but it first checks bucket if there is index-cached uploaded already. 
-  In the same time, compactor precomputes the index cache file on every compaction.

   New Compactor flag: `--index.generate-missing-cache-file` was added to allow quicker addition of index cache files. If enabled it precomputes missing files on compactor startup. Note that it will take time and it's only one-off step per bucket.

 - [#970](https://github.com/improbable-eng/thanos/pull/970) Deprecated `partial_response_disabled` proto field. Added `partial_response_strategy` instead. Both in gRPC and Query API.
   No `PartialResponseStrategy` field for `RuleGroups` by default means `abort` strategy (old PartialResponse disabled) as this is recommended option for Rules and alerts.
