First release through the beta channel — features settle on :beta before they move to :latest. If you run AUTO_SELFUPDATE on :latest, nothing changes for you: pre-releases never move that tag.
Network and disk I/O in the /status detail
docker stats hands them over in the same call that already fetches CPU and memory, so the two extra fields cost nothing:
📈 Load: CPU 0.02% · RAM 71.6MiB / 11.4GiB
📡 I/O: net 1.2MB / 800kB · disk 5.1MB / 0B
A runtime that reports fewer fields still yields the two that matter.
And the beta channel itself, documented
New features land on amayer1983/docksentry:beta first and move to :latest once they have settled — usually a day later, sooner when testers confirm. The README has the one-line compose change.
