 :::info[Changed in v0.40.0]
 
 Before v0.40.0, `thv run --network host` silently built the isolation sidecars
-against an internal-only network, which broke outbound DNS and connectivity on
-the next re-create. Isolation is now dropped for `host`/`none` modes so
-host-networked workloads keep working. If you rely on host networking, no change
-is needed on your side; if you previously combined `--isolate-network` with
-`--network host` explicitly, split them into two invocations depending on which
-one you actually need.

+Isolation is now dropped for `host`/`none` modes so host-networked workloads
+keep working. If you rely on host networking, no change is needed. If you
+previously combined `--isolate-network` with `--network host` explicitly, pick
+one: drop `--network host` to keep enforced isolation, or set
+`--isolate-network=false` to keep host networking.
