## 2.53.1 / 2024-07-10

Fix a bug which would drop samples in remote-write if the sending flow stalled
for longer than it takes to write one "WAL segment". How long this \ 
takes depends on the size
of your Prometheus; as a rough guide with 10 million series it is about 2-3 minutes.

* [BUGFIX] Remote-write: stop dropping samples in catch-up #14446
