• [CHANGE] Return Bad Request from all frontend endpoints if the tenant can't be extracted. #​5480 (@​carles-grafana)
• [CHANGE] BREAKING CHANGE Migrated Tempo Vulture and Integration Tests from the deprecated Jaeger agent/exporter to the standard OTLP exporter. Vulture now pushes traces to the Tempo OTLP GRCP endpoint. #​5058 (@​iamrajiv, @​javiermolinar)
• [CHANGE] Do not count cached querier responses for SLO metrics such as inspected bytes. #​5185 (@​carles-grafana)
• [CHANGE] Adjust the definition of tempo_metrics_generator_processor_service_graphs_expired_edges to exclude edges that are counted in the service graph. #​5319 (@​joe-elliott)
• [CHANGE] Command tempo-cli analyse block(s) excludes attributes with array values. #​5380 (@​stoewer)
• [CHANGE] Remove .005s and add a 1.5s bucket to all request duration histograms. #​5492 (@​joe-elliott)
• [CHANGE] Improve tempo writes dashboard. #​5500 (@​javiermolinar)

• [CHANGE] Drop tracing bridges in favor of OTEL only tracing. #​5594 (@​zalegrala)
• [CHANGE] BREAKING CHANGE Fix incorrect TraceQL metrics results when series labels include strings and integers with same textural representation.
  This also changes the TraceQL metrics responses of /api/metrics/query_range and /api/metrics/query to remove the redundant
  prom_labels field which was the error source. There may be an interruption to TraceQL metrics queries during rollout while components are running the previous version. #​5659 (@​mdisibio)

• [FEATURE] New block encoding vParquet5-preview1 with low-resolution timestamp columns for better TraceQL metrics performance. This format is in development and breaking changes are expected before final release. #​5495 (@​mdisibio)
• [FEATURE] New block encoding vParquet5-preview2 with dedicated attribute columns for integers. This format is in development and breaking changes are expected before final release. #​5639 (@​stoewer)
