+  [ Christian Perrier ]
   * Fix "typos" in French manpages translations. Thanks to
     Cyril Brulebois for bashing me.
   * Drop useless untranslatable sections from apt.8

+  * apt-pkg/aptconfiguration.cc:
+    - evaluate Acquire::Languages= before LANG= (Closes: #602573)
+  * apt-pkg/orderlist.cc:
+    - try fixing before removing even if the fix is hidden in
+      a provides, hidden in the #590438 testcase
+  * apt-pkg/algorithms.cc:
+    - if the package was explicitly marked as ToRemove don't
+      consider it as a candidate for FixByInstall
+  * apt-pkg/depcache.cc:
+    - don't install previously not installed providers in a try
+      to statisfy a "Breaks: provides" dependency by upgrade
