 * [ENHANCEMENT] Upgrade Thanos and promql-engine to latest. #7740
 * [ENHANCEMENT] Ruler: Adjust ruler frontend decoder to not wrap query error messages with execution prefix, this makes error responses consistent between internal and external ruler paths. #7741
 * [ENHANCEMENT] Distributor: Deduplicate metric metadata when converting PRW 2.0 requests. PRW 2.0 attaches metadata to every series, so a metric family was previously expanded into one `MetricMetadata` per series. #7760
+* [ENHANCEMENT] Update build image and Go version to 1.27.0. #7814
 * [BUGFIX] Querier: Fix queryWithRetry and labelsWithRetry returning (nil, nil) on cancelled context by propagating ctx.Err(). #7370
 * [BUGFIX] Metrics Helper: Fix non-deterministic bucket order in merged histograms by sorting buckets after map iteration, matching Prometheus client library behavior. #7380
 * [BUGFIX] Distributor: Return HTTP 401 Unauthorized when tenant ID resolution fails in the Prometheus Remote Write 2.0 path. #7389
