Update module github.com/prometheus/client_golang to v1.24.1 by renovate[bot] · Pull Request #602 · chaspy/aws-rds-maxcon-prometheus-exporter

`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

Full Changelog: prometheus/client_golang@v1.22.0...v1.23.0

`v1.22.0`: - 2025-04-07

⚠️ This release contains potential breaking change if you use experimental zstd support introduce in #1496 ⚠️

Experimental support for zstd on scrape was added, controlled by the request Accept-Encoding header.
It was enabled by default since version 1.20, but now you need to add a blank import to enable it.
The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon,
golang/go#62513 however, the work took longer than anticipated and it will be postponed to upcoming major Go versions.

e.g.:

import (
  _ "github.com/prometheus/client_golang/prometheus/promhttp/zstd"
)

[FEATURE] prometheus: Add new CollectorFunc utility #1724
[CHANGE] Minimum required Go version is now 1.22 (we also test client_golang against latest go version - 1.24) #1738
[FEATURE] api: WithLookbackDelta and WithStats options have been added to API client. #1743
[CHANGE] ⚠️ promhttp: Isolate zstd support and klauspost/compress library use to promhttp/zstd package. #1765
