 =head1 DESCRIPTION
 
 This document describes differences between the 5.9.2 and the 5.9.3
-developement releases. See L<perl590delta>, L<perl591delta> and
+development releases. See L<perl590delta>, L<perl591delta> and
 L<perl592delta> for the differences between 5.8.0 and 5.9.2.
 
 =head1 Incompatible Changes
 
+=head2 Parsing of C<-f _>
+
+C<_> is now forced to be a bareword after a filetest operator. This solves
+a number of misparsing issues when a global C<_> subroutine is defined.
+
+=head2 C<defined %foo::bar::>
+
+This used to report whether the C<foo::bar> package was created. Now it's
+always true, as a side-effect of a change to shrink the internal size of
+hash structures. Note that using C<defined> on hashes was deprecated
+anyway. To achieve the same result, you can use the following
+backwards-compatible idiom:
+
+    defined *foo::{HASH}->{'bar::'}
