Changelog for golang-github-prometheus-prometheus-2.53.0-116.8.i586.rpm :

* Fri Jun 28 2024 Witek Bedyk - Bump go-retryablehttp to version 0.7.7 (CVE-2024-6104, bsc#1227038)- Add 0003-Bump-go-retryablehttp.patch
* Wed Jun 19 2024 Johannes Kastl - update to 2.53.0: This release changes the default for GOGC, the Go runtime control for the trade-off between excess memory use and CPU usage. We have found that Prometheus operates with minimal additional CPU usage, but greatly reduced memory by adjusting the upstream Go default from 100 to 75.
* [CHANGE] Rules: Execute 1 query instead of N (where N is the number of alerts within alert rule) when restoring alerts. [#13980] #14048

* [BUGFIX] Scaleway SD: Use the instance\'s public IP if no private IP is available as the __address__ meta label. #13941
* [BUGFIX] Query logger: Do not leak file descriptors on error. [#13948]

* [ENHANCEMENT] TSDB: Improve Prometheus parser error outputs to be more comprehensible. #11682
* [ENHANCEMENT] UI: Scope `group by` labels to metric in autocompletion. #11914
* [BUGFIX] Scrape: Fix `prometheus_target_scrape_pool_target_limit` metric not set before reloading. #12002

* Tue Feb 28 2023 Johannes Kastl - fix building web assets (boo#1208752)- adjust packaging to build webassets locally, outside of OBS
* to get the UI working, newer versions of prometheus need the react app assets
* as running `npm install` inside of OBS is not possible, the required dependencies need to be prepared outside of OBS
* added a PACKAGING_README.md file, that explains how the new web-ui-
*.tar.gz and npm_licenses.tar.bz2 tarballs can be created
* Thu Feb 02 2023 Johannes Kastl - update to 2.42.0: This release comes with a bunch of feature coverage for native histograms and breaking changes. If you are trying native histograms already, we recommend you remove the `wal` directory when upgrading. Because the old WAL record for native histograms is not backward compatible in v2.42.0, this will lead to some data loss for the latest data. Additionally, if you scrape \"float histograms\" or use recording rules on native histograms in v2.42.0 (which writes float histograms), it is a one-way street since older versions do not support float histograms.
