 Highlights:
 
-* New Thanos component, [Query Frontend](https://thanos.io/tip/components/query-frontend.md/) has more options and supports shared cache (currently: Memcached).
-* Added debug mode in Thanos UI that allows to filter Stores to query from by their IPs from Store page (!). This helps enormously in e.g debugging the slowest store etc. All raw Thanos API allows passing
-`storeMatch[]` arguments with `__address__` matchers.
-* Improved debuggability on all Thanos components by exposing [off-CPU profiles thanks to fgprof endpoint](https://github.com/felixge/fgprof).
-* Significantly improved sidecar latency and CPU usage for metrics fetches.
