* [CHANGE] Experimental TSDB: switched the blocks storage index header to the binary format. This change is expected to have no visible impact, except lower startup times and memory usage in the queriers. It's possible to switch back to the old JSON format via the flag `-experimental.tsdb.bucket-store.binary-index-header-enabled=false`. #2223
* [CHANGE] Experimental Memberlist KV store can now be used in single-binary Cortex. Attempts to use it previously would fail with panic. This change also breaks existing binary protocol used to exchange gossip messages, so this version will not be able to understand gossiped Ring when used in combination with the previous version of Cortex. Easiest way to upgrade is to shutdown old Cortex installation, and restart it with new version. Incremental rollout works too, but with reduced functionality until all components run the same version. #2016
* [FEATURE] Added a read-only local alertmanager config store using files named corresponding to their tenant id. #2125
* [FEATURE] Added user sub rings to distribute users to a subset of ingesters. #1947
* `-experimental.distributor.user-subring-size`
* [FEATURE] Added flag `-experimental.ruler.enable-api` to enable the ruler api which implements the Prometheus API `/api/v1/rules` and `/api/v1/alerts` endpoints under the configured `-http.prefix`. #1999
* [FEATURE] Added sharding support to compactor when using the experimental TSDB blocks storage. #2113
* [FEATURE] Added ability to override YAML config file settings using environment variables. #2147

* [FEATURE] Add flag `-experimental.tsdb.stripe-size` to expose TSDB stripe size option. #2185
* [FEATURE] Experimental Delete Series: Added support for Deleting Series with Prometheus style API. Needs to be enabled first by setting `-purger.enable` to `true`. Deletion only supported when using `boltdb` and `filesystem` as index and object store respectively. Support for other stores to follow in separate PRs #2103
* [FEATURE] Introduced new standalone service `query-tee` that can be used for testing purposes to send the same Prometheus query to multiple backends (ie. two Cortex clusters ingesting the same metrics) and compare the performances. #2203
* [FEATURE] Fan out parallelizable queries to backend queriers concurrently. #1878

* [BUGFIX] The gauge `cortex_overrides_last_reload_successful` is now only exported by components that use a `RuntimeConfigManager`. Previously, for components that do not initialize a `RuntimeConfigManager` (such as the compactor) the gauge was initialized with 0 (indicating error state) and then never updated, resulting in a false-negative permanent error state. #2092
