 +    - fix a few typos in the comments of this files
 +
 +  [ David Kalnischkies ]
 +  * doc/Doxyfile.in:
 +    - update file with doxygen 1.6.1 (current unstable)

+ apt (0.7.23.1) UNRELEASED; urgency=low
+ 
+   [ Michael Vogt ]
+   * apt-pkg/pkgcache.cc:
+     - do not set internel "needs-configure" state for packages in 
+       triggers-pending state. dpkg will deal with the trigger and
+       it if does it before we trigger it, dpkg will error out
+       (LP: #414631)
+   * apt-pkg/acquire-item.cc:
+     - do not segfault on invalid items (closes: #544080)
