      * Previously, if a scrape failed, Prometheus erroneously considered the samples from the very next scrape as duplicates and dropped them. This issue affected only the scrape immediately following a failure, while subsequent scrapes were processed correctly. With this release, the scrape following a failure is now correctly handled, ensuring that no valid samples are mistakenly dropped. (link:https://issues.redhat.com/browse/OCPBUGS-53025[OCPBUGS-53025])
