-## Unreleased
+## v0.16.3 — 2026-11-03
+
+Replicas counted per profile — seven on cards and four on CPUs under one name, the cards filled first — and every
+setting of a served model from the mirror page; how fast a model answers on the CPU, said before it is served, by
+the threads it is given rather than the whole machine's memory.
+
+**Upgrading.**
+- No migrations. `llmgw ctl upgrade v0.16.3`: the control planes carry the replicas per profile, the model card and
+  the speed in the serve form and in `ctl model plan`; the agents carry the measurement of one core's memory rate,
+  without which the speed is reckoned the old way, from the whole machine's.
