We decided to revert the testutil change that made our util functions less error-prone, but created a lot of work for our downstream users. Apologies for the pain! This revert should not cause any major breaking change, even if you already did the work--unless you depend on the exact error message.
Going forward, we plan to reinforce our release testing strategy [1],[2] and deliver an enhanced testutil package/module with more flexible and safer APIs.
[BUGFIX] testutil: Reverted #1424; functions using compareMetricFamilies are (again) only failing if filtered metricNames are in the expected input. #1645
v1.20.4
[BUGFIX] histograms: Fix a possible data race when appending exemplars vs metrics gather. #1623
v1.20.3
[BUGFIX] histograms: Fix possible data race when appending exemplars. #1608
v1.20.2
[BUGFIX] promhttp: Unset Content-Encoding header when data is uncompressed. #1596
[BUGFIX] process-collector: Fixed unregistered descriptor error when using process collector with PedanticRegistry on Linux machines. #1587
v1.20.0
Thanks everyone for contributions!
:warning: In this release we remove one (broken anyway, given Go runtime changes) metric and add three new (representing GOGC, GOMEMLIMIT and GOMAXPROCS flags) to the default collectors.NewGoCollector() collector. Given its popular usage, expect your binary to expose two additional metric.
Changes
[CHANGE] :warning: go-collector: Remove go_memstat_lookups_total metric which was always 0; Go runtime stopped sharing pointer lookup statistics. #1577
[FEATURE] :warning: go-collector: Add 3 default metrics: go_gc_gogc_percent, go_gc_gomemlimit_bytes and go_sched_gomaxprocs_threads as those are recommended by the Go team. #1559
[FEATURE] go-collector: Add more information to all metrics' HELP e.g. the exact runtime/metrics sourcing each metric (if relevant). #1568#1578
[BUGFIX] testutil: Reverted #1424; functions using compareMetricFamilies are (again) only failing if filtered metricNames are in the expected input.

The module prometheus/common v0.48.0 introduced an incompatibility when used together with client_golang (See prometheus/client_golang#1448 for more details). If your project uses client_golang and you want to use prometheus/common v0.48.0 or higher, please update client_golang to v1.19.0.

[BUGFIX] testutil: Fix comparison of metrics with empty Help strings. #1378
[ENHANCEMENT] Improved performance of MetricVec.WithLabelValues(...). #1360
