 * [FEATURE] Introduced `ruler.for-grace-period`, Minimum duration between alert and restored "for" state. This is maintained only for alerts with configured "for" time greater than grace period. #2783
 * [FEATURE] Introduced `ruler.for-resend-delay`, Minimum amount of time to wait before resending an alert to Alertmanager. #2783
 * [ENHANCEMENT] Experimental: Querier can now optionally query secondary store. This is specified by using `-querier.second-store-engine` option, with values `chunks` or `tsdb`. Standard configuration options for this store are used. Additionally, this querying can be configured to happen only for queries that need data older than `-querier.use-second-store-before-time`. Default value of zero will always query secondary store. #2747
-* [BUGFIX] Fixed a bug in the index intersect code causing storage to return more chunks/series than required. #2796
 * [BUGFIX] Fixed the number of reported keys in the background cache queue. #2764
 * [BUGFIX] Fix race in processing of headers in sharded queries. #2762

 * [BUGFIX] Experimental TSDB: when the querier receives a `/series` request with a time range older than the data stored in the ingester, it now ignores the requested time range and returns known series anyway instead of returning an empty response. This aligns the behaviour with the chunks storage. #2617
 * [BUGFIX] Cassandra: fixed an edge case leading to an invalid CQL query when querying the index on a Cassandra store. #2639
 * [BUGFIX] Ingester: increment series per metric when recovering from WAL or transfer. #2674
-* [BUGFIX] Fixed `wrong number of arguments for 'mget' command` Redis error when a query has no chunks to lookup from storage. #2700
