⚠️ This release contains potential breaking change if you upgradegithub.com/prometheus/common to 0.62+ together with client_golang (and depend on the strict, legacy validation for the label names). New common versionchangesmodel.NameValidationScheme global variable, which relaxes the validation of label names and metric name, allowing all UTF-8 characters. Typically, this should not break any user, unless your test or usage expects strict certain names to panic/fail on client_golang metric registration, gathering or scrape. In case of problems changemodel.NameValidationScheme to oldmodel.LegacyValidation value in your projectinit function.⚠️

We decided to revertthetestutil 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 theexact error message.
Going forward, we plan to reinforce our release testing strategy[1],[2] and deliver an enhancedtestutil package/module with more flexible and safer APIs.

Thanks everyone for contributions!
⚠️ 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 defaultcollectors.NewGoCollector() collector. Given its popular usage, expect your binary to expose two additional metric.
Changes
- [CHANGE]⚠️ go-collector: Remove
go_memstat_lookups_total metric which was always 0; Go runtime stopped sharing pointer lookup statistics.#1577 - [FEATURE]⚠️ go-collector: Add 3 default metrics:
go_gc_gogc_percent,go_gc_gomemlimit_bytes andgo_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 - [FEATURE] testutil: Add CollectAndFormat method.#1503
- [FEATURE] histograms: Add support for exemplars in native histograms.#1471
- [FEATURE] promhttp: Add experimental support for
zstd on scrape, controlled by the requestAccept-Encoding header.#1496 - [FEATURE] api/v1: Add
WithLimit parameter to all API methods that supports it.#1544 - [FEATURE] prometheus: Add support for created timestamps in constant histograms and constant summaries.#1537
- [FEATURE] process-collectors: Add network usage metrics:
process_network_receive_bytes_total andprocess_network_transmit_bytes_total.#1555 - [FEATURE] promlint: Add duplicated metric lint rule.#1472
- [BUGFIX] promlint: Relax metric type in name linter rule.#1455
- [BUGFIX] promhttp: Make sure server
instrumentation wrapping supports new and future extra responseWriter methods.#1480 - [BUGFIX] testutil: Functions using compareMetricFamilies are now failing if filtered metricNames are not in the input.#1424

What's Changed
The moduleprometheus/common v0.48.0 introduced an incompatibility when used together with client_golang (Seehttps://github.com/prometheus/client_golang/pull/1448 for more details). If your project uses client_golang and you want to useprometheus/common v0.48.0 or higher, please update client_golang to v1.19.0.
- [CHANGE] Minimum required go version is now 1.20 (we also test client_golang against new 1.22 version).#1445#1449
- [FEATURE] collectors: Add version collector.#1422#1427
