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
[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] 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
