v1.22.0 - 2025-04-07
⚠️ This release contains potential breaking change if you use experimentalzstd support introduce in#1496⚠️
Experimental support forzstd on scrape was added, controlled by the requestAccept-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since version 1.20, but now you need to add a blank import to enable it.The decision to make it opt-in by default was originally made because the Go standard library was expected to have default zstd support added soon,golang/go#62513 however, the work took longer than anticipated and it will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.
