   - The documentation for cvsimport has been majorly improved.
 
+  - "git-show-ref --exclude-existing" was documented.

 * Bugfixes
 
+  - The implementation of -p option in "git cvsexportcommit" had
+    the meaning of -C (context reduction) option wrong, and
+    loosened the context requirements when it was told to be
+    strict.
+
+  - "git cvsserver" did not behave like the real cvsserver when
+    client side removed a file from the working tree without
+    doing anything else on the path.  In such a case, it should
+    restore it from the checked out revision.
+
+  - "git fsck" issued an alarming error message on detached
+    HEAD.  It is not an error since at least 1.5.0.
+
   - "git send-email" produced of References header of unbounded length;
     fixed this with line-folding.
