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. +* Significantly improved query performance on Store Gateway, Querier, Ruler and Receive by introducing zero allocation gRPC label encoding / decoding. + ### Fixed - [#3234](https://github.com/thanos-io/thanos/pull/3234) UI: Fix assets not loading when `--web.prefix-header` is used. +- [#3184](https://github.com/thanos-io/thanos/pull/3184) Compactor: Fixed support for `web.external-prefix` for Compactor UI. ### Added -- [#3032](https://github.com/thanos-io/thanos/pull/3032) Query Frontend: Added support for Memacahce cache. Replaced underscores with hyphens in `log_queries_longer_than - > log-queries-longer-than`. +- [#3114](https://github.com/thanos-io/thanos/pull/3114) Query Frontend: Added support for Memacached cache. + - **breaking** Renamed flag `log_queries_longer_than` to `log-queries-longer-than`. - [#3166](https://github.com/thanos-io/thanos/pull/3166) UIs: Added UI for passing a `storeMatch[]` parameter to queries. -- [#3184](https://github.com/thanos-io/thanos/pull/3184) Compact: Fix web.prefix-header to use &wc.prefixHeaderName -- [#3181](https://github.com/thanos-io/thanos/pull/3181) Logging: Add debug level logging for responses between 300-399 -- [#3133](https://github.com/thanos-io/thanos/pull/3133) Query: Allow passing a `storeMatch[]` to Labels APIs. Also time range metadata based store filtering is supported on Labels APIs. -- [#3154](https://github.com/thanos-io/thanos/pull/3154) Query Frontend: Add metric `thanos_memcached_getmulti_gate_queries_max`. -- [#3146](https://github.com/thanos-io/thanos/pull/3146) Sidecar: Add `thanos_sidecar_prometheus_store_received_frames` histogram metric. -- [#3147](https://github.com/thanos-io/thanos/pull/3147) Querier: Add `query.metadata.default-time-range` flag to specify the default metadata time range duration for retrieving labels through Labels and Series API when the range parameters are not specified.

Added `thanos_sidecar_prometheus_store_received_frames` histogram metric. +- [#3147](https://github.com/thanos-io/thanos/pull/3147) Querier: Added `query.metadata.default-time-range` flag to specify the default metadata time range duration for retrieving labels through Labels and Series API when the range parameters are not specified.
