It might look like a small release, but it's quite opposite 😱 There were many non user facing changes and fixes and enormous work from engineers from Grafana to add native histograms in 💪🏾 Enjoy! 😍

What's Changed

  • [FEATURE] Add Support for Native Histograms. #​1150
  • [CHANGE] Extend prometheus.Registry to implement prometheus.Collector interface. #​1103

Compare Source

  • [CHANGE] Minimum required Go version is now 1.17 (we also test client_golang against the new 1.19 version).
  • [ENHANCEMENT] Added prometheus.TransactionalGatherer interface for promhttp.Handler use which allows using low allocation update techniques for custom collectors. #​989
  • [ENHANCEMENT] Added exemplar support to prometheus.NewConstHistogram. See ExampleNewConstHistogram_WithExemplar example on how to use it. #​986
  • [ENHANCEMENT] Query requests are now retried after network error. #​1022
  • [ENHANCEMENT] prometheus/push.Pusher now has context-aware methods that pass context to HTTP requests. #​1028
  • [ENHANCEMENT] prometheus/push.Pusher has now Error method that retrieve last error. #​1075
  • [ENHANCEMENT] testutil.GatherAndCompare provides now readable diff on failed comparisons. #​998
  • [ENHANCEMENT] Query API now supports timeouts. #​1014
  • [ENHANCEMENT] New MetricVec method DeletePartialMatch(labels Labels) for deleting all metrics that match provided labels. #​1013
  • [ENHANCEMENT] api.Config now accepts passing custom *http.Client. #​1025
  • [BUGFIX] Raise exemplar labels limit from 64 to 128 bytes as specified in OpenMetrics spec. #​1091
  • [BUGFIX] Allow adding exemplar to +Inf bucket to const histograms. #​1094
  • [ENHANCEMENT] Most promhttp.Instrument* middlewares now support adding exemplars to metrics. This allows hooking those to your tracing middleware that retrieves trace ID and puts it in exemplar if present. #​1055
  • [ENHANCEMENT] Added testutil.ScrapeAndCompare method. #​1043
  • [BUGFIX] Fixed GopherJS build support. #​897

v1.12.2: 1.12.2 / 2022-05-13

Compare Source

  • [CHANGE] Added collectors.WithGoCollections that allows to choose what collection of Go runtime metrics user wants: Equivalent of MemStats structure configured using GoRuntimeMemStatsCollection, new based on dedicated runtime/metrics metrics represented by GoRuntimeMetricsCollection option, or both by specifying GoRuntimeMemStatsCollection | GoRuntimeMetricsCollection flag.
  • [CHANGE] Change in collectors.NewGoCollector metrics: Reverting addition of new ~80 runtime metrics by default. You can enable this back with GoRuntimeMetricsCollection option or GoRuntimeMemStatsCollection | GoRuntimeMetricsCollection for smooth transition.
  • [BUGFIX] Fixed the bug that causes generated histogram metric names to end with _total. ️ This changes 3 metric names in the new Go collector that was reverted from default in this release.
    • go_gc_heap_allocs_by_size_bytes_total -> go_gc_heap_allocs_by_size_bytes,
    • go_gc_heap_frees_by_size_bytes_total -> go_gc_heap_allocs_by_size_bytes
    • go_gc_pauses_seconds_total -> go_gc_pauses_seconds.
  • [CHANGE] Removed -Inf buckets from new Go Collector histograms.
