+  [ David Kalnischkies ]
+  * apt-pkg/indexcopy.cc:
+    - rename RunGPGV to ExecGPGV and move it to apt-pkg/contrib/gpgv.cc
+  * apt-pkg/contrib/gpgv.cc:
+    - ExecGPGV is a method which should never return, so mark it as such
+      and fix the inconsistency of returning in error cases
+    - don't close stdout/stderr if it is also the statusfd
+    - if ExecGPGV deals with a clear-signed file it will split this file
+      into data and signatures, pass it to gpgv for verification
+    - add method to open (maybe) clearsigned files transparently
+  * apt-pkg/acquire-item.cc:
+    - keep the last good InRelease file around just as we do it with
+      Release.gpg in case the new one we download isn't good for us
+  * apt-pkg/deb/debmetaindex.cc:
+    - reenable InRelease by default
+  * ftparchive/writer.cc,
+    apt-pkg/deb/debindexfile.cc,
+    apt-pkg/deb/deblistparser.cc:
+    - use OpenMaybeClearSignedFile to be free from detecting and
+      skipping clearsigning metadata in dsc and Release files
+
+  [ Michael Vogt ]
+  * add regression test for CVE-2013-1051
+  * implement GPGSplit() based on the idea from Ansgar Burchardt
