-          <para>As a general principle, the FreeBSD core team only release
-            a new version of FreeBSD when they believe that there are
-            sufficient new features and/or bug fixes to justify one, and
-            are satisfied that these new developments have been tested
-            sufficiently to avoid compromising the stability of the
-            release.  Release dates are generally announced well in

+            a new version of FreeBSD about every four months, on
+            average.  Release dates are announced well in
             advance, so that the people working on the system know
             when their projects need to be finished and tested.  
+	    A testing period precedes each release, in order to ensure

             can be a little frustrating.</para>
