+.SH "Core Enhancements"
+.IX Header "Core Enhancements"
+The perl interpreter is now more tolerant of UTF\-16\-encoded scripts.
+.PP
+On Win32, Perl can now use non-IFS compatible LSPs, which allows Perl to
+work in conjunction with firewalls such as McAfee Guardian. For full details
+see the file \fI\s-1README\s0.win32\fR, particularly if you're running Win95.

+.SH "Utility Changes"
+.IX Header "Utility Changes"
+Perl has a new \-dt command-line flag, which enables threads support in the
+debugger.
+.SH "Performance Enhancements"
+.IX Header "Performance Enhancements"
+\&\f(CW\*(C`reverse sort ...\*(C'\fR is now optimized to sort in reverse, avoiding the
+generation of a temporary intermediate list.
+.PP
+\&\f(CW\*(C`for (reverse @foo)\*(C'\fR now iterates in reverse, avoiding the generation of a
+temporary reversed list.
+.SH "Selected Bug Fixes"
+.IX Header "Selected Bug Fixes"
+The regexp engine is now more robust when given invalid utf8 input, as is
+sometimes generated by buggy \s-1XS\s0 modules.
+.PP
+\&\f(CW\*(C`foreach\*(C'\fR on threads::shared array used to be able to crash Perl. This bug
+has now been fixed.
+.PP
+A regexp in \f(CW\*(C`STDOUT\*(C'\fR's destructor used to coredump, because the regexp pad
+was already freed. This has been fixed.
+.PP
+\&\f(CW\*(C`goto &\*(C'\fR is now more robust \- bugs in deep recursion and chained \f(CW\*(C`goto &\*(C'\fR
+have been fixed.
+.PP
+Using \f(CW\*(C`delete\*(C'\fR on an array no longer leaks memory. A \f(CW\*(C`pop\*(C'\fR of an item from a
+shared array reference no longer causes a leak.
+.PP
+\&\f(CW\*(C`eval_sv()\*(C'\fR failing a taint test could corrupt the stack \- this has been
+fixed.
+.PP
+On platforms with 64 bit pointers numeric comparison operators used to
+erroneously compare the addresses of references that are overloaded, rather
+than using the overloaded values. This has been fixed.
+.PP
+\&\f(CW\*(C`read\*(C'\fR into a UTF8\-encoded buffer with an offset off the end of the buffer
+no longer mis-calculates buffer lengths.
+.PP
+Although Perl has promised since version 5.8 that \f(CW\*(C`sort()\*(C'\fR would be
+stable, the two cases \f(CW\*(C`sort {$b cmp $a}\*(C'\fR and \f(CW\*(C`sort {$b <=> $a}\*(C'\fR could
+produce non-stable sorts.   This is corrected in perl5.8.6.
+.PP
+Localising \f(CW$^D\fR no longer generates a diagnostic message about valid \-D
+flags.
+.SH "New or Changed Diagnostics"
+.IX Header "New or Changed Diagnostics"
+For \-t and \-T,
+   Too late for \*(L"\-T\*(R" option
+has been changed to the more informative
+   \*(L"\-T\*(R" is on the #! line, it must also be used on the command line
+.SH "Changed Internals"
+.IX Header "Changed Internals"
+From now on all applications embedding perl will behave as if perl
+were compiled with \-DPERL_USE_SAFE_PUTENV.  See \*(L"Environment access\*(R" in
+the \fI\s-1INSTALL\s0\fR file for details.
+.PP
+Most \f(CW\*(C`C\*(C'\fR source files now have comments at the top explaining their purpose,
+which should help anyone wishing to get an overview of the implementation.
+.SH "New Tests"
+.IX Header "New Tests"
+There are significantly more tests for the \f(CW\*(C`B\*(C'\fR suite of modules.
+.SH "Reporting Bugs"
+.IX Header "Reporting Bugs"
+If you find what you think is a bug, you might check the articles
+recently posted to the comp.lang.perl.misc newsgroup and the perl
+bug database at http://bugs.perl.org.  There may also be
+information at http://www.perl.org, the Perl Home Page.
+.PP
+If you believe you have an unreported bug, please run the \fBperlbug\fR
+program included with your release.  Be sure to trim your bug down
+to a tiny but sufficient test case.  Your bug report, along with the
+output of \f(CW\*(C`perl \-V\*(C'\fR, will be sent off to perlbug@perl.org to be
+analysed by the Perl porting team.  You can browse and search
+the Perl 5 bugs at http://bugs.perl.org/
