+# Container image updates in .NET 11 Preview 7 - Release Notes
+
+.NET 11 Preview 7 contains no new user-facing container image features. The
+Azure Linux 4.0 image rollout begun in Preview 6 is complete — the remaining
+Azure Linux 4.0 tag variants were backported to the Preview 7 branch in
+[dotnet/dotnet-docker #7290](https://github.com/dotnet/dotnet-docker/pull/7290) —
+and the smaller Native AOT SDK images introduced in Preview 6 are unchanged.
+
+For features that shipped earlier in the release, see the
+[Preview 6 container notes](../preview6/containers.md).
+
+The only non-infrastructure change in this preview is a Chisel update to
+`v1.4.2` for the distroless image build
+([dotnet/dotnet-docker #7298](https://github.com/dotnet/dotnet-docker/pull/7298)).
+
+<!-- No net-new container features shipped between the P6 (2026-07-14) and P7
+     (2026-08-11) windows. Merged PRs against dotnet/dotnet-docker in that
+     window are #7290 (Azure Linux 4.0 P6 backport), #7295/#7297 (network
+     isolation policy, infra), and #7298 (Chisel v1.4.2). Everything else is
+     nightly dependency flow. -->
