-## Unreleased
+## v0.15.3 — 2026-10-29
+
+A model stopped and kept, or removed with its files; the second mirror fixed where it was tried.
+
+**Upgrading.**
+- No migrations. The control planes carry stop, start and purge; the nodes need nothing new.
+- The mirrors carry the fixes: on each mirror's machine, `sudo llmgw upgrade v0.15.3 --service llmgw-mirror`.
+  A mirror with a peer then works out the checksums its older files lack, once, which reads every such file.
