+
+* [CHANGE] Completely rewritten storage layer, with WAL. This is not backwards compatible with 1.x storage, and many flags have changed/disappeared.

+* [CHANGE] Removed `count_scalar`, `drop_common_labels` functions and `keep_common` modifier from PromQL.
+* [CHANGE] Rewritten exposition format parser with much higher performance. The Protobuf exposition format is no longer supported.
+* [CHANGE] Example console templates updated for new storage and metrics names. Examples other than node exporter and Prometheus removed.
+* [CHANGE] Admin and lifecycle APIs now disabled by default, can be reenabled via flags
+* [CHANGE] Flags switched to using Kingpin, all flags are now --flagname rather than -flagname.
+* [FEATURE/CHANGE] Remote read can be configured to not read data which is available locally. This is enabled by default.
+* [FEATURE] Rules can be grouped now. Rules within a rule group are executed sequentially.
