Release notes

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

v1.24.0 - 2026-07-20

Changes

• [CHANGE] Minimum required Go version is now 1.25, only the two latest Go versions (1.25 and 1.26) are supported from now on. #1862
• [CHANGE] prometheus: Name validation now always uses the UTF-8 scheme instead of the deprecated model.NameValidationScheme global. Default behavior is unchanged; code that set NameValidationScheme = LegacyValidation no longer gets legacy enforcement at metric, label, and push-grouping construction. #2051
• [CHANGE] api/prometheus/v1: Support matchers (matches[] parameter) in Rules method (Rules(ctx context.Context, matches []string) (RulesResult, error)). #1843
• [CHANGE] api/prometheus/v1: Refactor LabelNames method to return model.LabelNames instead of []string for consistency across the API. #1850
• [CHANGE] exp/api/remote: Simplify Store interface, rename Handler to WriteHandler, and encapsulate write response handling. #1855
• [FEATURE] prometheus: Add new Go 1.26 runtime metrics (/sched/goroutines-created:goroutines, /sched/goroutines/not-in-go:goroutines, /sched/goroutines/runnable:goroutines, /sched/goroutines/running:goroutines, /sched/goroutines/waiting:goroutines, /sched/threads/total:threads). #1942
• [FEATURE] prometheus: Add WithUnit(unit string) option and explicit OpenMetrics unit support in CounterOpts, GaugeOpts, SummaryOpts, and HistogramOpts. #1392
• [FEATURE] prometheus: Expose descriptor construction error through public Err() method on Desc. #1902
• [FEATURE] promhttp: Add opt-in HandlerOpts.CoalesceGather to deduplicate concurrent Gather calls so overlapping scrapes share one collection cycle, preventing goroutine pile-up when the scrape rate outpaces collection time. #1969
• [FEATURE] promhttp: HTTP handlers created by promhttp package now support metrics filtering by providing one or more name[] query parameters. The default behavior when none are provided remains the same, returning all metrics. #1925
• [FEATURE] api/prometheus/v1: Add query formatting endpoint support (/format_query) and FormatQuery(ctx context.Context, query string) (string, error) method. #1846, #1856
• [FEATURE] api/prometheus/v1: Add support for /status/tsdb/blocks endpoint via TSDBBlocks(ctx context.Context) ([]TSDBBlock, error) method. #1896
• [FEATURE] exp/api/remote: Export BackoffConfig to allow customization when using WithAPIBackoff. #1895
• [FEATURE] exp/api/remote: Add RetryCallBack to allow custom logging or handling on retry attempts in the remote write client. #1888, #1890
• [ENHANCEMENT] prometheus/collectors/version: Allow specifying custom labels when registering the version collector. #1860
• [ENHANCEMENT] api: Use cloned http.DefaultTransport when constructing default HTTP clients to prevent accidental mutations of shared global transport state. #1885
• [BUGFIX] prometheus: Recover from collector panics during Gather() and return an error instead of crashing the process. #1961
• [BUGFIX] prometheus: Fix cpu-seconds unit suffix handling for metric go_cpu_classes_gc_mark_assist_cpu_seconds. #1991
• [BUGFIX] promhttp: InstrumentHandlerDuration and InstrumentHandlerCounter no longer panic when given an observer/counter that does not implement ExemplarObserver/ExemplarAdder (e.g. a SummaryVec). The exemplar is dropped and the value is recorded via the plain Observe/Add path, matching the safe-cast already used by Timer.ObserveDurationWithExemplar. #2005
• [BUGFIX] api/prometheus/v1: Fall back to GET requests when POST requests return 403 Forbidden or method not allowed. #2030
• [BUGFIX] api: Respect context cancellation inside httpClient.Do. #1971
• [BUGFIX] exp/api/remote: Fix compression buffer pooling where compressed buffers were released prematurely, causing corrupted remote-write payloads. #1889
• [BUGFIX] exp/api/remote: Reject malformed snappy payloads declaring huge decoded sizes. Enforce a 32MB decoded-size limit to prevent OOM from oversized remote-write requests. #1917
• [BUGFIX] exp/api/remote: Ensure remote write v2 headers cannot be returned on v1 requests. #1927

Prometheus client dependency

Layer / File(s)	Summary
Update Prometheus client version go.mod	The required Prometheus client version changes from v1.23.2 to v1.24.0.

Estimated code review effort: 1 (Trivial) | ~2 minutes

🚥 Pre-merge checks | ✅ 15

✅ Passed checks (15 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly and accurately summarizes the dependency version bump in go.mod.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	Diff only updates go.mod/go.sum; no Ginkgo test titles were added or modified.
Test Structure And Quality	✅ Passed	PR only bumps go.mod/go.sum for client_golang; no Ginkgo test code changed, so the test-structure checklist is not applicable.
Microshift Test Compatibility	✅ Passed	PR only updates go.mod/go.sum for client_golang; no test files or new Ginkgo e2e specs were added, so no MicroShift-specific risk.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	Only go.mod/go.sum changed; no Ginkgo tests were added or modified, so there are no SNO-specific assumptions to review.
Topology-Aware Scheduling Compatibility	✅ Passed	Only go.mod/go.sum changed for a dependency bump; no manifests, operators, or controllers were modified, so no topology-aware scheduling impact.
Ote Binary Stdout Contract	✅ Passed	Only go.mod/go.sum changed; no main/init/suite code or stdout-writing paths were modified, so the OTE stdout contract is unaffected.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	Only go.mod and go.sum changed; no Ginkgo/e2e test files were added or modified, so IPv4/external-connectivity checks are not applicable.
No-Weak-Crypto	✅ Passed	Only go.mod/go.sum changed; the diff contains no MD5/SHA1/DES/RC4/3DES/Blowfish/ECB usage, custom crypto, or secret comparisons.
Container-Privileges	✅ Passed	Only go.mod/go.sum changed; no container manifests or privilege settings were added or modified.
No-Sensitive-Data-In-Logs	✅ Passed	Diff only updates go.mod/go.sum for client_golang; no code or log statements changed.

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

I'm waiting for a openshift 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.
