⚠️ 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The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon,
https://github.com/golang/go/issues/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

This release addresses a performance regression introduced in #​1661 -- thanks to all who reported this quickly:
@​chlunde, @​dethi, @​aaronbee @​tsuna @​kakkoyun 💪🏽. This patch release also fixes the iOS build.

We will be hardening the release process even further (#​1759, #​1761) to prevent this in future, sorry for the inconvenience!

The high concurrency optimization is planned to be eventually reintroduced, however in a much safer manner, potentially in a separate API.

• [BUGFIX] prometheus: Revert of Inc, Add and Observe cumulative metric CAS optimizations (#​1661), causing regressions on low concurrency cases #​1757
• [BUGFIX] prometheus: Fix GOOS=ios build, broken due to process_collector_* wrong build tags. #​1758

All commits

• Revert "exponential backoff for CAS operations on floats" and cut 1.21.1 by @​bwplotka in https://github.com/prometheus/client_golang/pull/1757
• Fix ios build for 1.21.1 by @​bwplotka in https://github.com/prometheus/client_golang/pull/1758
