 - [#6192](https://github.com/thanos-io/thanos/pull/6192) Store: add flag `bucket-web-label` to select the label to use as timeline title in web UI
 - [#6167](https://github.com/thanos-io/thanos/pull/6195) Receive: add flag `tsdb.too-far-in-future.time-window` to prevent clock skewed samples to pollute TSDB head and block all valid incoming samples.
 - [#6273](https://github.com/thanos-io/thanos/pull/6273) Mixin: Allow specifying an instance name filter in dashboards
+- [#6163](https://github.com/thanos-io/thanos/pull/6163) Receiver: Add hidden flag `--receive-forward-max-backoff` to configure the max backoff for forwarding requests.

 - [#6244](https://github.com/thanos-io/thanos/pull/6244) mixin(Rule): Add rule evaluation failures to the Rule dashboard.
 - [#6303](https://github.com/thanos-io/thanos/pull/6303) Store: added and start using streamed snappy encoding for postings list instead of block based one. This leads to constant memory usage during decompression. This approximately halves memory usage when decompressing a postings list in index cache.
 - [#6071](https://github.com/thanos-io/thanos/pull/6071) Query Frontend: *breaking :warning:* Add experimental native histogram support for which we updated and aligned with the [Prometheus common](https://github.com/prometheus/common) model, which is used for caching so a cache reset required.
+- [#6163](https://github.com/thanos-io/thanos/pull/6163) Receiver: changed max backoff from 30s to 5s for forwarding requests. Can be configured with `--receive-forward-max-backoff`.
