This is a bug-fix release, reverting a change introduced in v2.51.0.
The bug was that remote-write would drop samples if the sending flow
stalled for longer than it takes to write one "WAL segment". How long
this takes depends on the data rate of your Prometheus; as a rough guide
with 10 million series scraping once per minute it could be about 5
minutes. The issue is
[#​14087](https://redirect.github.com/prometheus/prometheus/issues/14087).

This release changes the default for GOGC, the Go runtime control for
the trade-off between excess memory use and CPU usage. We have found
that Prometheus operates with minimal additional CPU usage, but greatly
reduced memory by adjusting the upstream Go default from 100 to 75.

of alerts within alert rule) when restoring alerts.
