⚠️ 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The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon,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:
WithLookbackDeltaandWithStatsoptions have been added to API client. #1743 - [CHANGE] ⚠️ promhttp: Isolate zstd support and klauspost/compress library use to promhttp/zstd package. #1765
