 **2024:**
 
+- [2024-08](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/163506): Updated Sidekiq configuration for Prometheus in Monitoring node on 2k.
 - [2024-08](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/162144): Added Next Steps breadcrumb section to the pages to help discoverability of additional features.
 - [2024-05](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/153716): Updated the 60 RPS / 3k User and 100 RPS / 5k User pages to have latest Redis guidance on co-locating Redis Sentinel with Redis itself.
 - [2024-05](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/153579): Renamed `Cost to run` section to `Cost calculator templates` to better reflect the calculators are only a starting point and need to be adjusted with specific usage to give more accurate cost estimates.
