1.22.0 / 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 The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon, golang/go#62513 however, the work took longer than anticipated and it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

1.21.1 / 2025-03-04

  • [BUGFIX] prometheus: Revert of Inc, Add and Observe cumulative metric CAS optimizations (#1661), causing regressions on low contention cases.
  • [BUGFIX] prometheus: Fix GOOS=ios build, broken due to process_collector_* wrong build tags.

1.21.0 / 2025-02-17

⚠️ This release contains potential breaking change if you upgrade github.com/prometheus/common to 0.62+ together with client_golang. ⚠️

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
  • [ENHANCEMENT] prometheus: Optimize popular prometheus.BuildFQName function; now up to 30% faster. #1665
  • [ENHANCEMENT] 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
