+  * apt-pkg/pkgcachegen.cc:
+    - ensure that dependencies for packages:none are always generated
+    - add 3 missing remap registrations causing a segfault in case
+      we use the not remapped iterators after a move of the mmap again
+  * apt-pkg/pkgcache.cc:
+    - ignore negative dependencies applying in the same group for

+  * cmdline/apt-cache.cc:
+    - print versioned dependency relations in (r)depends if the option
+      APT::Cache::ShowVersion is true (default: false) as discussed in
+      #218995 to help debian-cd fixing #687949. Thanks to Sam Lidder
+      for initial patch and Steve McIntyre for nagging and testing!
