+    </links>
+
+    <body>
+      <p>Support for following children after forks for &os; was implemented and
+	merged upstream to GDB's master branch, and was included in GDB
+	7.10.</p>
+
+      <p>Work has continued on porting <tt>kgdb</tt> to newer
+	<tt>gdb</tt>.  The amd64, i386, powerpc, powerpc64, and sparc64
+	backends have all been ported and are now available via a new
+	<tt>KGDB</tt> option in the devel/gdb port.</p>
+
+      <p>The MD backends for libkvm have been rewritten to support
+	cross-debugging crashdumps, and the <tt>kgdb</tt> targets for
+	amd64 and i386 have been reworked to support cross-debugging.
+	Both i386 and amd64 kgdb binaries have been able to cross-debug
+	the other architecture's vmcores with these changes.  This
+	changeset for libkvm is not yet in the tree, but is awaiting more
+	testing.</p>
