 - [#5844](https://github.com/thanos-io/thanos/pull/5844) Query Frontend: Fixes @ modifier time range when splitting queries by interval.
-- [#5854](https://github.com/thanos-io/thanos/pull/5854) Query Frontend: Handles `lookback_delta` param in query frontend.
+- [#5854](https://github.com/thanos-io/thanos/pull/5854) Query Frontend: `lookback_delta` param is now handled in query frontend.
+- [#5860](https://github.com/thanos-io/thanos/pull/5860) Query: Fixed bug of not showing query warnings in Thanos UI.
+- [#5856](https://github.com/thanos-io/thanos/pull/5856) Store: Fixed handling of debug logging flag.
 - [#5230](https://github.com/thanos-io/thanos/pull/5230) Rule: Stateless ruler support restoring `for` state from query API servers. The query API servers should be able to access the remote write storage.
 - [#5880](https://github.com/thanos-io/thanos/pull/5880) Query Frontend: Fixes some edge cases of query sharding analysis.
 - [#5893](https://github.com/thanos-io/thanos/pull/5893) Cache: Fixed redis client not respecting `SetMultiBatchSize` config value.
-- [#5966](https://github.com/thanos-io/thanos/pull/5966) Query: Fixed mint and maxt when selecting series for the `api/v1/series` HTTP endpoint.
+- [#5966](https://github.com/thanos-io/thanos/pull/5966) Query: Stop relying on non-existent hints for mint and maxt when selecting series for the `api/v1/series` HTTP endpoint.
+- [#5948](https://github.com/thanos-io/thanos/pull/5948) Store: `chunks_fetched_duration` wrong calculation.
+- [#5910](https://github.com/thanos-io/thanos/pull/5910): Receive: Fixed ketama quorum bug that was could cause success response for failed replication. This also optimize heavily receiver CPU use.
 
 ### Added
 
-- [#5945](https://github.com/thanos-io/thanos/pull/5945) Tools: Added new `no-downsample` marker to skip blocks when downsampling via `thanos tools bucket mark --marker=no-downsample-mark.json`. This will skip downsampling for blocks with the new marker.
-- [#5814](https://github.com/thanos-io/thanos/pull/5814) Store: Add metric `thanos_bucket_store_postings_size_bytes` that shows the distribution of how many postings (in bytes) were needed for each Series() call in Thanos Store. Useful for determining limits.
-- [#5801](https://github.com/thanos-io/thanos/pull/5801) Store: add a new limiter `--store.grpc.downloaded-bytes-limit` that limits the number of bytes downloaded in each Series/LabelNames/LabelValues call. Use `thanos_bucket_store_postings_size_bytes` for determining the limits.
-- [#5839](https://github.com/thanos-io/thanos/pull/5839) Receive: Add parameter `--tsdb.out-of-order.time-window` to set time window for experimental out-of-order samples ingestion. Disabled by default (set to 0s). Please note if you enable this option and you use compactor, make sure you set the `--enable-vertical-compaction` flag, otherwise you might risk compactor halt.
-- [#5836](https://github.com/thanos-io/thanos/pull/5836) Receive: Add hidden flag `tsdb.memory-snapshot-on-shutdown` to enable experimental TSDB feature to snapshot on shutdown. This is intended to speed up receiver restart.
+- [#5814](https://github.com/thanos-io/thanos/pull/5814) Store: Added metric `thanos_bucket_store_postings_size_bytes` that shows the distribution of how many postings (in bytes) were needed for each Series() call in Thanos Store. Useful for determining limits.
+- [#5703](https://github.com/thanos-io/thanos/pull/5703) StoreAPI: Added `hash` field to series' chunks. Store gateway and receive implements that field and proxy leverage that for quicker deduplication.
+- [#5801](https://github.com/thanos-io/thanos/pull/5801) Store: Added a new flag `--store.grpc.downloaded-bytes-limit` that limits the number of bytes downloaded in each Series/LabelNames/LabelValues call. Use `thanos_bucket_store_postings_size_bytes` for determining the limits.
+- [#5836](https://github.com/thanos-io/thanos/pull/5836) Receive: Added hidden flag `tsdb.memory-snapshot-on-shutdown` to enable experimental TSDB feature to snapshot on shutdown. This is intended to speed up receiver restart.

Disabled by default (set to 0s). Please note if you enable this option and you use compactor, make sure you set the `--enable-vertical-compaction` flag, otherwise you might risk compactor halt.
+- [#5889](https://github.com/thanos-io/thanos/pull/5889) Query Frontend: Added support for vertical sharding `label_replace` and `label_join` functions.
 - [#5865](https://github.com/thanos-io/thanos/pull/5865) Compact: Retry on sync metas error.
-- [#5889](https://github.com/thanos-io/thanos/pull/5889) Query Frontend: Support sharding vertical sharding `label_replace` and `label_join` functions.
-- [#5819](https://github.com/thanos-io/thanos/pull/5819) Store: Add a few objectives for Store's data touched/fetched amount and sizes. They are: 50, 95, and 99 quantiles.
+- [#5819](https://github.com/thanos-io/thanos/pull/5819) Store: Added a few objectives for Store's data summaries (touched/fetched amount and sizes). They are: 50, 95, and 99 quantiles.
+- [#5837](https://github.com/thanos-io/thanos/pull/5837) Store: Added streaming retrival of series from object storage.
 - [#5940](https://github.com/thanos-io/thanos/pull/5940) Objstore: Support for authenticating to Swift using application credentials.
-- [#5977](https://github.com/thanos-io/thanos/pull/5977) Tools: Added remove flag on bucket mark command to remove deletion, no-downsample or no-compact markers on the block.
+- [#5945](https://github.com/thanos-io/thanos/pull/5945) Tools: Added new `no-downsample` marker to skip blocks when downsampling via `thanos tools bucket mark --marker=no-downsample-mark.json`. This will skip downsampling for blocks with the new marker.

 ### Changed
 
-- [#5716](https://github.com/thanos-io/thanos/pull/5716) DNS: Fix miekgdns resolver LookupSRV to work with CNAME records.
+- [#5785](https://github.com/thanos-io/thanos/pull/5785) Query: `thanos_store_nodes_grpc_connections` now trimms `external_labels` label name longer than 1000 character. It also allows customizations in what labels to preserve using `query.conn-metric.label` flag.
+- [#5542](https://github.com/thanos-io/thanos/pull/5542) Mixin: Added query concurrency panel to Querier dashboard. 
 - [#5846](https://github.com/thanos-io/thanos/pull/5846) Query Frontend: vertical query sharding supports subqueries.
-- [#5909](https://github.com/thanos-io/thanos/pull/5909) Receive: compact tenant head after no appends have happened for 1.5 `tsdb.max-block-size`.
-- [#5593](https://github.com/thanos-io/thanos/pull/5593) Cache: switch Redis client to [Rueidis](https://github.com/rueian/rueidis). Rueidis is [faster](https://github.com/rueian/rueidis#benchmark-comparison-with-go-redis-v9) and provides [client-side caching](https://redis.io/docs/manual/client-side-caching/). It is highly recommended to use it so that repeated requests for the same key would not be needed.
-- [#5896](https://github.com/thanos-io/thanos/pull/5896) *: Upgrade Prometheus to v0.40.7 without implementing native histogram support. *Querying native histograms will fail with `Error executing query: invalid chunk encoding "<unknown>"` and native histograms in write requests are ignored.*
+- [#5909](https://github.com/thanos-io/thanos/pull/5909) Receive: Compact tenant head after no appends have happened for 1.5 `tsdb.max-block-size`.

+- [#5922](https://github.com/thanos-io/thanos/pull/5922) Compact: Retry on clean, partial marked errors when possible.
