+## 2.32.0-beta.0 / 2021-11-16
+
+This beta release introduces the Prometheus Agent, a new mode of operation for
+Prometheus optimized for remote-write only scenarios. In this mode, Prometheus
+does not generate blocks on the local filesystem and is not queryable locally.
+Enable with `--enable-feature=agent`.
+
+Learn more about the Prometheus Agent in our [blog post](https://prometheus.io/blog/2021/11/16/agent/).

+* [CHANGE] remote-write: Change default max retry time from 100ms to 5 seconds. #9634
+* [FEATURE] Agent: New mode of operation optimized for remote-write only scenarios, without local storage. Enable with `--enable-feature=agent`. #8785
+* [FEATURE] Promtool: Add `promtool check service-discovery` command. #8970
+* [FEATURE] UI: Add search in metrics dropdown. #9629
+* [FEATURE] Templates: Add parseDuration to template functions. #8817
+* [ENHANCEMENT] Promtool: Improve test output. #8064

+* [ENHANCEMENT] Remote-write: Reuse memory for marshalling. #9412
+* [ENHANCEMENT] Scrape: Add `scrape_body_size_bytes` scrape metric behind the `--enable-feature=extra-scrape-metrics` flag. #9569
+* [ENHANCEMENT] TSDB: Add windows arm64 support. #9703
+* [ENHANCEMENT] TSDB: Optimize query by skipping unneeded sorting in TSDB. #9673
+* [ENHANCEMENT] Templates: Support int and uint as datatypes for template formatting. #9680
+* [ENHANCEMENT] UI: Prefer `rate` over `rad`, `delta` over `deg`, and `count` over `cos` in autocomplete. #9688
+* [BUGFIX] TSDB: Add more size checks when writing individual sections in the index. #9710
+* [BUGFIX] PromQL: Make `deriv()` return zero values for constant series. #9728
+
+## 2.31.1 / 2021-11-05

 ## More information

-  * The source code is periodically indexed: [Prometheus Core](https://pkg.go.dev/github.com/prometheus/prometheus).
+  * The source code is periodically indexed, but due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead, you can use [the docs for v2.31.1](https://pkg.go.dev/github.com/prometheus/prometheus@v1.8.2-0.20211105201321-411021ada9ab).
  * You will find a CircleCI configuration in [`.circleci/config.yml`](.circleci/config.yml).
  * See the [Community page](https://prometheus.io/community) for how to reach the Prometheus developers and users on various communication channels.
