[dependabot]

Bumps the gomod-dependencies group with 1 update: github.com/prometheus/client_golang.

Updates github.com/prometheus/client_golang from 1.20.5 to 1.21.0

Release notes

Sourced from github.com/prometheus/client_golang's releases.

v1.21.0 / 2025-02-19

⚠️ This release contains potential breaking change if you upgrade github.com/prometheus/common to 0.62+ together with client_golang (and depend on the strict, legacy validation for the label names). New common version changes model.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 change model.NameValidationScheme to old model.LegacyValidation value in your project init function. ⚠️

• [BUGFIX] gocollector: Fix help message for runtime/metric metrics. #1583
• [BUGFIX] prometheus: Fix Desc.String() method for no labels case. #1687
• [PERF] prometheus: Optimize popular prometheus.BuildFQName function; now up to 30% faster. #1665
• [PERF] prometheus: Optimize Inc, Add and Observe cumulative metrics; now up to 50% faster under high concurrent contention. #1661
• [CHANGE] Upgrade prometheus/common to 0.62.0 which changes model.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 invoke CloseIdleConnections on api.Client using api.Client.(CloseIdler).CloseIdleConnections() casting. #1513
• [FEATURE] promhttp: Add promhttp.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: Add NewConstNativeHistogram function. #1654

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
