+
+The Warewulf project is pleased to announce the release of v4.5.7, [now
+available on GitHub][1].
+
+[1]: https://github.com/warewulf/warewulf/releases/tag/v4.5.7
+
+Warewulf v4.5.7 fixes the ability to override overlay files configured in
+profiles with overlays configured per-node; fixes a template processing bug bug
+in development-time overlay rendering; and improves the preview dracut-based
+boot process to better support a "secure" boot process.
+
+It also adds the ability to temporarily copy files into containers for possible
+modification during `wwctl container exec` and `wwctl container shell`.
+
+[Let us know][2] if you encounter any issues. [v4.5.8 is already planned][3],
+and we intend to continue to improve and maintain [the v4.5.x line][4] while
+working on [the next major release, v4.6.0][5].
