+Warewulf v4.6.0 is a significant upgrade, with many changes relative to the v4.5.x series:
+
+- new configuration upgrade system
+- changes to the default profile
+- renaming containers to (node) images
+- new kernel management system
+- parallel overlay builds
+- sprig functions in overlay templates
+- improved network overlays
+- nested profiles
+- arbitrary "resources" data in nodes.conf
+- NFS client configuration in nodes.conf
+- emphatically optional syncuser
+- improved network boot observability
+- movements towards Debian/Ubuntu support
+
+Particularly significant changes, especially those affecting the user interface, are described in the [release notes](https://warewulf.org/docs/v4.6.x/release/v4.6.0.html). Additional changes not impacting the user interface are listed in the [CHANGELOG](https://github.com/warewulf/warewulf/blob/main/CHANGELOG.md).
