• [CHANGE] API: /api/v1/status/config now correctly shows separator: "" and replacement: "" in relabel configs when explicitly set to empty, instead of omitting them. #18653
• [CHANGE] Discovery/Hetzner: Drop the __meta_hetzner_datacenter label for hcloud targets, following its removal from the Hetzner Cloud API. #19269
• [CHANGE] PromQL: Enable duration expressions by default. The promql-duration-expr feature flag is now a no-op. #19033
• [CHANGE] PromQL: Promote first_over_time to stable. It no longer requires the promql-experimental-functions feature flag. #19093
• [FEATURE] Discovery: Add Oracle Cloud Infrastructure compute service discovery (oci_sd_configs). #18919
• [FEATURE] PromQL: Add experimental start_timestamp(instant-vector) function returning the start timestamp of each sample in the given vector. Requires the use-start-timestamps feature flag. #19089
• [FEATURE] PromQL: Allow rate() and increase() to use start timestamps as an alternative for rate extrapolation. Hidden behind the use-start-timestamps feature flag. #18619
• [FEATURE] TSDB: Add experimental support for encoding start timestamps in histograms and float histograms. Hidden behind the histograms-st-encoding feature flag. #18609
• [ENHANCEMENT] OTLP: Emit a warning when OTLP attribute names collide into the same Prometheus label after sanitization (e.g. k8s.pod.name and k8s_pod_name both become k8s_pod_name), and expose the prometheus_api_otlp_translation_warnings_total counter labelled by category to track such warnings. #18957

• [PERF] Scrape: Reduce native histogram scrape parsing allocations by ~49%. #19282
• [PERF] TSDB: Speed up queries on series with many in-memory chunks. #18300
• [BUGFIX] Alerting: Fix 100% CPU usage on shutdown that could delay graceful shutdown and trigger timeout-based kills. #17859
• [BUGFIX] Discovery/AWS: Stop promtool check config from making AWS metadata service (IMDS) network calls when the region field is omitted in EC2, ECS, RDS, MSK, ElastiCache, and Lightsail service discovery configs. #19037
• [BUGFIX] Discovery/Docker: Set a request timeout for docker_sd and dockerswarm_sd on unix, npipe, and tcp hosts. Previously an unresponsive daemon could freeze discovery indefinitely, silently pinning targets to a stale snapshot. #19237

• [BUGFIX] TSDB: Fix prometheus_tsdb_head_stale_series over-counting and early eviction of series that change between float, integer histogram, and float histogram sample types. #19183
• [BUGFIX] TSDB: Fix goroutine and file handle leaks when Prometheus fails to open a corrupt TSDB. On Windows, the leaked directory handle also prevented TSDB directory removal. #18291
• [BUGFIX] TSDB: Fix out-of-order queries blocking compaction for hours, causing memory usage to grow. #19013
• [BUGFIX] TSDB: Fix deleted series causing missing samples and errors after restart. #19140
• [BUGFIX] TSDB: Fix native histogram data becoming incorrect after restart. #19202
