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

Compare Source

⚠️ 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
