 One side effect of these changes is that blessing into "\0" no longer

+=head2 Autoloaded sort Subroutines
 
 Custom sort subroutines can now be autoloaded [perl #30661]:
 
     sub AUTOLOAD { ... }
     @sorted = sort foo @list; # uses AUTOLOAD
 
+=head2 Improved typemaps for Some Builtin Types
+
+Most XS authors will be aware that there is a longstanding bug
+in the OUTPUT typemap for T_AVREF (C<AV*>), T_HVREF (C<HV*>),
+T_CVREF (C<CV*>), and T_SVREF (C<SVREF> or C<\$foo>) that requires
+manually decrementing the reference count of the return value
+instead of the typemap taking care of this. For
+backwards-compatibility, this cannot be changed in the default
+typemaps. But we now provide additional typemaps
+C<T_AVREF_REFCOUNT_FIXED>, etc. that do not exhibit this bug.
+Using them in your extension is as simple as having one line
+in your C<TYPEMAP> section:
+
+  HV*  T_HVREF_REFCOUNT_FIXED

+L<base> has been upgraded from version 2.17 to version 2.18.
+
+C<base> no longer sets a module's C<$VERSION> to "-1" when a module it loads
+does not define a C<$VERSION>.  This change has been made because "-1" is not
+a valid version number under the new "lax" criteria used internally by
+C<UNIVERSAL::VERSION>.  (See L<version> for more on "lax" version criteria.)
+
+C<base> no longer internally skips loading modules it has already loaded and
+instead relies on C<require> to inspect C<%INC>.  This fixes a bug when C<base>
+is used with code that clear C<%INC> to force a module to be reloaded.
