Bumps github.com/prometheus/client_golang from 1.23.2 to 1.25.0.

Release notes

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

v1.25.0

⚠️ This release raises the minimum required Go version to 1.26 and includes breaking API changes in api/prometheus/v1 (see the [CHANGE] entries below). ⚠️

1.25.0 / 2026-10-07

  • [CHANGE] Minimum required Go version is now 1.26, only the two latest Go versions (1.26 and 1.27) are supported from now on. #2138
  • [CHANGE] api/prometheus/v1: Query, QueryRange, Series, LabelNames, and LabelValues now return Infos annotations in addition to Warnings, matching the Prometheus server's info annotations. This changes the signatures of these methods and of api.Client's Do/DoGetFallback; custom API client implementations must be updated. #1963
  • [CHANGE] api/prometheus/v1: Rework TSDBBlocks result types to align with the Prometheus server's tsdb.BlockMeta: TSDBBlocksResult now contains Blocks []TSDBBlockMeta directly instead of mirroring the full API envelope, nested types are renamed (TSDBBlockMeta, TSDBBlockStats, TSDBBlockMetaCompaction), stat fields are uint64 with omitempty tags, and the optional compaction parents field is included. #1928
  • [FEATURE] testutil: Add GatherAndFormat to encode a subset of metrics from a Gatherer. #2091
  • [FEATURE] promhttp: Add HandlerOpts.AcceptedFormats to customize the formats negotiated from the incoming Accept header, enabling opt-in to experimental formats such as OpenMetrics 2.0 without changing default negotiation. #2146
  • [ENHANCEMENT] promhttp: Negotiated metrics responses now include a Vary header. #2142
  • [ENHANCEMENT] prometheus: Regenerate the default runtime collector metrics for Go 1.25 and Go 1.26. #2090, #2095
  • [ENHANCEMENT] testutil: Finalize OpenMetrics output in GatherAndFormat and CollectAndFormat (terminating # EOF). #2125
  • [BUGFIX] api: Match complete URL path placeholders only; a :foo argument no longer substitutes inside :foobar. #2136
  • [BUGFIX] exp/api/remote: Reset the pooled buffer before generic proto marshaling, preventing corrupted remote-write payloads. #2139
  • [BUGFIX] testutil/promlint: Fix "mibi" unit prefix to "mebi". #2135

1.24.1 / 2026-07-23

  • [BUGFIX] promhttp: Fix panic on requests with nil URL. #2065

1.24.0 / 2026-07-20

  • [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
