v1.20.1

This release contains the critical fix for theissue. Thanks to@​geberl,@​CubicrootXYZ,@​zetaab and@​timofurrer for helping us with the investigation!

• [BUGFIX] process-collector: Fixed unregistered descriptor error when using process collector with PedanticRegistry on Linux machines.#1587

v1.20.0

Thanks everyone for contributions!

⚠️ In this release we remove one (broken anyway, given Go runtime changes) metric and add three new (representing GOGC, GOMEMLIMIT and GOMAXPROCS flags) to the defaultcollectors.NewGoCollector() collector. Given its popular usage, expect your binary to expose two additional metric.

Changes

• [CHANGE]⚠️ go-collector: Removego_memstat_lookups_total metric which was always 0; Go runtime stopped sharing pointer lookup statistics.#1577
