+---
+
+## [Release 40.2](https://rpm-software-management.github.io/mock/Release-Notes-Configs-40.2) - 2024-02-16
+
+### Mock Core Configs changes
+
+- Per the approved [Fedora 40 change](https://fedoraproject.org/wiki/Changes/BuildWithDNF5),
+  [we switched][PR#1332] the default `package_manager` configuration
+  for Fedora 40 or newer to `dnf5`.
+  This was previously done when Fedora 40 was Rawhide,
+  but it [regressed][rhbz#2264535] when Fedora 40 branched.
