+apt (0.8.3ubuntu7) UNRELEASED; urgency=low
+
+  [ David Kalnischkies ]
+  * apt-pkg/depcache.cc:
+    - do not remove packages which the user requested for installation
+      explicitly while satisfying other install requests (Closes: #598669)
+    Test case: debootstrap, install exim4, run "apt-get install postfix"
+    This will result in exim4-heavy instead of postfix
