+=head2 DTrace probes for interpreter phase change
+
+The C<phase-change> probes will fire when the interpreter's phase
+changes, which tracks the C<${^GLOBAL_PHASE}> variable. C<arg0> is
+the new phase name; C<arg1> is the old one. This is useful mostly
+for limiting your instrumentation to one or more of: compile time,
+run time, destruct time.

+L<ExtUtils::ParseXS> has been upgraded from version XXX to version XXX.
+
+Much of L<ExtUtils::ParseXS>, the module behind the XS compiler C<xsubpp>,
+was rewritten and cleaned up. It has been made somewhat more extensible
+and now finally uses strictures.
+
+The logic for parsing, merging, and dumping XS typemaps was extracted
+from C<ExtUtils::ParseXS> into a module of its own, L<ExtUtils::Typemaps>.
+C<ExtUtils::Typemaps> offers an interface to typemap handling outside of
+the scope of the XS compiler itself.
+
+As a first use case of the improved API an extensibility, typemaps can now
+be included inline into XS code with a HEREDOC-like syntax:
+
+ TYPEMAP: <<END_TYPEMAP
+ MyType T_IV
+ END_TYPEMAP

+[THINGS THAT MAY BREAK YOUR CODE]
+
+C<url()> was fixed to return C<PATH_INFO> when it is explicitly requested
+with either the path=>1 or path_info=>1 flag.
+
+If your code is running under mod_rewrite (or compatible) and you are calling C<self_url()> or
+you are calling C<url()> and passing path_info=>1, These methods will actually be
+returning C<PATH_INFO> now, as you have explicitly requested, or has C<self_url()>
+has requested on your behalf.
+
+The C<PATH_INFO> has been omitted in such URLs since the issue was introduced
+in the 3.12 release in December, 2005.
+
+This bug is so old your application may have come to depend on it or
+workaround it. Check for application before upgrading to this release.
+
+Examples of affected method calls:
+
+ $q->url(-absolute => 1, -query => 1, -path_info => 1 )
+ $q->url(-path=>1)
+ $q->url(-full=>1,-path=>1)
+ $q->url(-rewrite=>1,-path=>1)
+ $q->self_url();
