1.5.0 / 2022-11-29

NOTE: This changes the Go runtime "GOMAXPROCS" to 1. This is done to limit the
concurrency of the exporter to 1 CPU thread at a time in order to avoid a
race condition problem in the Linux kernel (#2500) and parallel IO issues
on nodes with high numbers of CPUs/CPU threads (#1880).
