VPA's recommender was silently ignoring metric flags when querying Prometheus history, causing recommendations to restart from scratch instead of building on past data.

Vertical Pod Autoscaler 1.7.1 landed with two critical fixes for the recommender [1]. The first addresses a regression where the --history-cpu-metric and --history-memory-metric flags were ignored when using the Prometheus history provider, causing historical queries to skip the configured metric name entirely [1]. The second restores checkpoint loading to prevent recommendations from restarting from scratch [1]. Both regressions would have forced unnecessary recommendation churn in production. The chart version 0.11.0 now defaults to this release [2]. Meanwhile, kube-state-metrics gained two observability improvements: it now logs when a configured custom resource CRD is absent instead of silently generating no metrics [3], and added support for label generation on ephemeral volumes to align with upstream PVC naming conventions [4]. Documentation continues its steady refresh across multiple languages, with Portuguese-Brazilian, French, and Japanese docs migrating to the newer code_sample shortcode [5] [6].
