 ### Fixed
 
-- [#2033](https://github.com/thanos-io/thanos/pull/2033) minio-go: Fixed Issue #1494 support Web Identity providers for IAM credentials for AWS EKS
-- [#1985](https://github.com/thanos-io/thanos/pull/1985) store gateway: Fixed case where series entry is larger than 64KB in index.
-- [#2051](https://github.com/thanos-io/thanos/pull/2051) ruler: Fixed issue where ruler does not expose shipper metrics.
-- [#2101](https://github.com/thanos-io/thanos/pull/2101) ruler: Fixed bug where thanos_alert_sender_errors_total was not registered.
+- [#2288](https://github.com/thanos-io/thanos/pull/2288) Ruler: Fixes issue #2281 bug in ruler with parsing query addr with path prefix
+- [#2238](https://github.com/thanos-io/thanos/pull/2238) Ruler: Fixed Issue #2204 bug in alert queue signalling filled up queue and alerts were dropped
+- [#2231](https://github.com/thanos-io/thanos/pull/2231) Bucket Web - Sort chunks by thanos.downsample.resolution for better grouping
+- [#2254](https://github.com/thanos-io/thanos/pull/2254) Bucket: Fix metrics registered multiple times in bucket replicate
+- [#2271](https://github.com/thanos-io/thanos/pull/2271) Bucket Web: Fixed Issue #2260 bucket passes null when storage is empty
+- [#2339](https://github.com/thanos-io/thanos/pull/2339) Query: fix a bug where `--store.unhealthy-timeout` was never respected
 
 ### Added
 
-- [#1969](https://github.com/thanos-io/thanos/pull/1969) Sidecar: allow setting http connection pool size via flags
-- [#1967](https://github.com/thanos-io/thanos/issues/1967) Receive: Allow local TSDB compaction
-- [#1970](https://github.com/thanos-io/thanos/issues/1970) *breaking* Receive: Use gRPC for forwarding requests between peers. Note that existing values for the `--receive.local-endpoint` flag and the endpoints in the hashring configuration file must now specify the receive gRPC port and must be updated to be a simple `host:port` combination, e.g. `127.0.0.1:10901`, rather than a full HTTP URL, e.g. `http://127.0.0.1:10902/api/v1/receive`.
+- [#2252](https://github.com/thanos-io/thanos/pull/2252) Query: add new `--store-strict` flag. More information available [here](/docs/proposals/202001_thanos_query_health_handling.md).
+- [#2265](https://github.com/thanos-io/thanos/pull/2265) Compactor: Add `--wait-interval` to specify compaction wait interval between consecutive compact runs when `--wait` enabled.
+- [#2250](https://github.com/thanos-io/thanos/pull/2250) Compactor: Enable vertical compaction for offline deduplication (Experimental). Uses `--deduplication.replica-label` flag to specify the replica label to deduplicate on (Hidden). Please note that this uses a NAIVE algorithm for merging (no smart replica deduplication, just chaining samples together). This works well for deduplication of blocks with **precisely the same samples** like produced by Receiver replication. We plan to add a smarter algorithm in the following weeks.
+- [#1714](https://github.com/thanos-io/thanos/pull/1714) Run the bucket web UI in the compact component when it is run as a long-lived process.
+- [#2304](https://github.com/thanos-io/thanos/pull/2304) Store: Added `max_item_size` config option to memcached-based index cache. This should be set to the max item size configured in memcached (`-I` flag) in order to not waste network round-trips to cache items larger than the limit configured in memcached.
+- [#2297](https://github.com/thanos-io/thanos/pull/2297) Store Gateway: Add `--experimental.enable-index-cache-postings-compression` flag to enable reencoding and compressing postings before storing them into cache. Compressed postings take about 10% of the original size.
+- [#2357](https://github.com/thanos-io/thanos/pull/2357) Compactor and Store Gateway now have serve BucketUI on `:<http-port>/loaded` and shows exactly the blocks that are currently seen by compactor and store gateway. Compactor also serves different BucketUI on `:<http-port>/global` that shows the status of object storage without any filters.
+
+### Changed
+
+- [#2136](https://github.com/thanos-io/thanos/pull/2136) *breaking* store, compact, bucket: schedule block deletion by adding deletion-mark.json. This adds a consistent way for multiple readers and writers to access object storage.
+Since there are no consistency guarantees provided by some Object Storage providers, this PR adds a consistent lock-free way of dealing with Object Storage irrespective of the choice of object storage. In order to achieve this co-ordination, blocks are not deleted directly. Instead, blocks are marked for deletion by uploading `deletion-mark.json` file for the block that was chosen to be deleted. This file contains unix time of when the block was marked for deletion. If you want to keep existing behavior, you should add `--delete-delay=0s` as a flag.
+- [#2090](https://github.com/thanos-io/thanos/issues/2090) *breaking* Downsample command: the `downsample` command has moved as the `thanos bucket` sub-command, and cannot be called via `thanos downsample` any more.
+- [#2294](https://github.com/thanos-io/thanos/pull/2294) store: optimizations for fetching postings. Queries using `=~".*"` matchers or negation matchers (`!=...` or `!~...`) benefit the most.
+- [#2301](https://github.com/thanos-io/thanos/pull/2301) Ruler: initlialization fails with filepath bad pattern error and rule manager update error.
+- [#2310](https://github.com/thanos-io/thanos/pull/2310) query: Report timespan 0 to 0 when discovering no stores.
+- [#2330](https://github.com/thanos-io/thanos/pull/2330) store: index-header is no longer experimental. It is enabled by default for store Gateway. You can disable it with new hidden flag: `--store.disable-index-header`. `--experimental.enable-index-header` flag was removed.

+### Fixed

+- [#2033](https://github.com/thanos-io/thanos/pull/1978) Ruler: Fix tracing in Thanos Ruler
+
+### Added
+
+- [#2003](https://github.com/thanos-io/thanos/pull/2003) Query: Support downsampling for /series.
+- [#1952](https://github.com/thanos-io/thanos/pull/1952) Store Gateway: Implemented [binary index header](https://thanos.io/proposals/201912_thanos_binary_index_header.md/). This significantly reduces resource consumption (memory, CPU, net bandwidth) for startup and data loading processes as well as baseline memory. This means that adding more blocks into object storage, without querying them will use almost no resources. This, however, **still means that querying large amounts of data** will result in high spikes of memory and CPU use as before, due to simply fetching large amounts of metrics data. Since we fixed baseline, we are now focusing on query performance optimizations in separate initiatives. To enable experimental `index-header` mode run store with hidden `experimental.enable-index-header` flag.
+- [#2009](https://github.com/thanos-io/thanos/pull/2009) Store Gateway: Minimum age of all blocks before they are being read. Set it to a safe value (e.g 30m) if your object storage is eventually consistent. GCS and S3 are (roughly) strongly consistent.
+- [#1963](https://github.com/thanos-io/thanos/pull/1963) Mixin: Add Thanos Ruler alerts.
+- [#1984](https://github.com/thanos-io/thanos/pull/1984) Query: Add cache-control header to not cache on error.
+- [#1870](https://github.com/thanos-io/thanos/pull/1870) UI: Persist settings in query.
+- [#1969](https://github.com/thanos-io/thanos/pull/1969) Sidecar: allow setting http connection pool size via flags.
+- [#1967](https://github.com/thanos-io/thanos/issues/1967) Receive: Allow local TSDB compaction.
 - [#1939](https://github.com/thanos-io/thanos/pull/1939) Ruler: Add TLS and authentication support for query endpoints with the `--query.config` and `--query.config-file` CLI flags. See [documentation](docs/components/rule.md/#configuration) for further information.
 - [#1982](https://github.com/thanos-io/thanos/pull/1982) Ruler: Add support for Alertmanager v2 API endpoints.
 - [#2030](https://github.com/thanos-io/thanos/pull/2030) Query: Add `thanos_proxy_store_empty_stream_responses_total` metric for number of empty responses from stores.
 - [#2049](https://github.com/thanos-io/thanos/pull/2049) Tracing: Support sampling on Elastic APM with new sample_rate setting.
 - [#2008](https://github.com/thanos-io/thanos/pull/2008) Querier, Receiver, Sidecar, Store: Add gRPC [health check](https://github.com/grpc/grpc/blob/master/doc/health-checking.md) endpoints.
-- [#2121](https://github.com/thanos-io/thanos/pull/2121) ui: Add React UI from Prometheus upstream
+- [#2145](https://github.com/thanos-io/thanos/pull/2145) Tracing: track query sent to prometheus via remote read api.
+- [#1848](https://github.com/thanos-io/thanos/pull/1848) Ruler: Return error messages when trigger reload with http.
+- [#2113](https://github.com/thanos-io/thanos/pull/2113) Bucket: Added `thanos bucket replicate`.
 
 ### Changed
 
+- [#1970](https://github.com/thanos-io/thanos/issues/1970) *breaking* Receive: Use gRPC for forwarding requests between peers. Note that existing values for the `--receive.local-endpoint` flag and the endpoints in the hashring configuration file must now specify the receive gRPC port and must be updated to be a simple `host:port` combination, e.g. `127.0.0.1:10901`, rather than a full HTTP URL, e.g. `http://127.0.0.1:10902/api/v1/receive`.
 - [#1933](https://github.com/thanos-io/thanos/pull/1933) Add a flag `--tsdb.wal-compression` to configure whether to enable tsdb wal compression in ruler and receiver.
 - [#2021](https://github.com/thanos-io/thanos/pull/2021) Rename metric `thanos_query_duplicated_store_address` to `thanos_query_duplicated_store_addresses_total` and `thanos_rule_duplicated_query_address` to `thanos_rule_duplicated_query_addresses_total`.
+- [#2166](https://github.com/thanos-io/thanos/pull/2166) Improve tooltip for bucket web UI.
