 Git 2.4 Release Notes
 =====================
 
+Backward compatibility warning(s)
+---------------------------------
+
+Output from "git log --decorate" (and "%d" format specifier used in
+the userformat "--format=<string>" parameter "git log" family of
+command takes) used to list "HEAD" just like other tips of branch
+names, separated with a comma in between.  E.g.
+
+    $ git log --decorate -1 master
+    commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD, master)
+    ...
+
+This release updates the output slightly when HEAD refers to the tip
+of a branch whose name is also shown in the output.  The above is
+shown as:
+
+    $ git log --decorate -1 master
+    commit bdb0f6788fa5e3cacc4315e9ff318a27b2676ff4 (HEAD -> master)
+    ...
