⚠️ 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.⚠️

[BUGFIX] gocollector: Fix help message for runtime/metric metrics.#1583
[BUGFIX] prometheus: FixDesc.String() method for no labels case.#1687
[PERF] prometheus: Optimize popularprometheus.BuildFQName function; now up to 30% faster.#1665
[PERF] prometheus: OptimizeInc,Add andObserve cumulative metrics; now up to 50% faster under high concurrent contention.#1661
[CHANGE] Upgrade prometheus/common to 0.62.0 which changesmodel.NameValidationScheme global variable.#1712
[CHANGE] Add support for Go 1.23.#1602
[FEATURE] process_collector: Add support for Darwin systems.#1600 #1616 #1625 #1675 #1715
[FEATURE] api: Add ability to invokeCloseIdleConnections on api.Client usingapi.Client.(CloseIdler).CloseIdleConnections() casting.#1513
[FEATURE] promhttp: Addpromhttp.HandlerOpts.EnableOpenMetricsTextCreatedSamples option to create OpenMetrics _created lines. Not recommended unless you want to use opt-in Created Timestamp feature. Community works on OpenMetrics 2.0 format that should make those lines obsolete (they increase cardinality significantly).#1408
[FEATURE] prometheus: AddNewConstNativeHistogram function.#1654
