-=head1 NAME
-
-perl583delta - what is new for perl v5.8.3
-
-=head1 DESCRIPTION
-
-This document describes differences between the 5.8.2 release and
-the 5.8.3 release.
-
-If you are upgrading from an earlier release such as 5.6.1, first read
-the L<perl58delta>, which describes differences between 5.6.0 and
-5.8.0, and the L<perl581delta> and L<perl582delta>, which describe differences
-between 5.8.0, 5.8.1 and 5.8.2
-
-=head1 Incompatible Changes
-
-There are no changes incompatible with 5.8.2.
-
-=head1 Core Enhancements
-
-A C<SCALAR> method is now available for tied hashes. This is called when
-a tied hash is used in scalar context, such as
-
- if (%tied_hash) {
- ...
- }
-
-
-The old behaviour was that %tied_hash would return whatever would have been
-returned for that hash before the hash was tied (so usually 0). The new
-behaviour in the absence of a SCALAR method is to return TRUE if in the
-middle of an C<each> iteration, and otherwise call FIRSTKEY to check if the
-hash is empty (making sure that a subsequent C<each> will also begin by
-calling FIRSTKEY). Please see L<perltie/SCALAR> for the full details and
-caveats.

-=item FindBin
-
-A function C<again> is provided to resolve problems where modules in different
-directories wish to use FindBin.
-

-
-C<cond_wait> has a new two argument form. C<cond_timedwait> has been added.
-

-
-=head1 Utility Changes
-
-C<find2perl> now assumes C<-print> as a default action. Previously, it
-needed to be specified explicitly.
-
-A new utility, C<prove>, makes it easy to run an individual regression test
-at the command line. C<prove> is part of Test::Harness, which users of earlier
-Perl versions can install from CPAN.
-
-=head1 New Documentation
-
-The documentation has been revised in places to produce more standard manpages.
-
-The documentation for the special code blocks (BEGIN, CHECK, INIT, END)
-has been improved.
-
-=head1 Installation and Configuration Improvements
-
-Perl now builds on OpenVMS I64
-
-=head1 Selected Bug Fixes
-
-Using substr() on a UTF8 string could cause subsequent accesses on that
-string to return garbage. This was due to incorrect UTF8 offsets being
-cached, and is now fixed.
-
-join() could return garbage when the same join() statement was used to
-process 8 bit data having earlier processed UTF8 data, due to the flags
-on that statement's temporary workspace not being reset correctly. This
-is now fixed.
-
-C<$a .. $b> will now work as expected when either $a or $b is C<undef>
-
-Using Unicode keys with tied hashes should now work correctly.
-
-Reading $^E now preserves $!. Previously, the C code implementing $^E
-did not preserve C<errno>, so reading $^E could cause C<errno> and therefore
-C<$!> to change unexpectedly.
-
-Reentrant functions will (once more) work with C++. 5.8.2 introduced a bugfix
-which accidentally broke the compilation of Perl extensions written in C++
-
-=head1 New or Changed Diagnostics
-
-The fatal error "DESTROY created new reference to dead object" is now
-documented in L<perldiag>.
-
-=head1 Changed Internals
-
-The hash code has been refactored to reduce source duplication. The
-external interface is unchanged, and aside from the bug fixes described
-above, there should be no change in behaviour.
-
-C<hv_clear_placeholders> is now part of the perl API
-
-Some C macros have been tidied. In particular macros which create temporary
-local variables now name these variables more defensively, which should
-avoid bugs where names clash.
-
-<signal.h> is now always included.
-
-=head1 Configuration and Building
-
-C<Configure> now invokes callbacks regardless of the value of the variable
-they are called for. Previously callbacks were only invoked in the
-C<case $variable $define)> branch. This change should only affect platform
-maintainers writing configuration hints files.
-
-=head1 Platform Specific Problems
-
-The regression test ext/threads/shared/t/wait.t fails on early RedHat 9
-and HP-UX 10.20 due to bugs in their threading implementations.
-RedHat users should see https://rhn.redhat.com/errata/RHBA-2003-136.html
-and consider upgrading their glibc.
-
-=head1 Known Problems
-
-Detached threads aren't supported on Windows yet, as they may lead to
-memory access violation problems.
-
-There is a known race condition opening scripts in C<suidperl>. C<suidperl>
-is neither built nor installed by default, and has been deprecated since
-perl 5.8.0. You are advised to replace use of suidperl with tools such
-as sudo ( http://www.courtesan.com/sudo/ )
-
-We have a backlog of unresolved bugs. Dealing with bugs and bug reports
-is unglamorous work; not something ideally suited to volunteer labour,
-but that is all that we have.
-
-The perl5 development team are implementing changes to help address this
-problem, which should go live in early 2004.
-
-=head1 Future Directions
-
-Code freeze for the next maintenance release (5.8.4) is on March 31st 2004,
-with release expected by mid April. Similarly 5.8.5's freeze will be at
-the end of June, with release by mid July.
-
-=head1 Obituary
-
-Iain 'Spoon' Truskett, Perl hacker, author of L<perlreref> and
-contributor to CPAN, died suddenly on 29th December 2003, aged 24.
-He will be missed.
-
-=head1 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.
-
-If you believe you have an unreported bug, please run the B<perlbug>
-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 C<perl -V>, 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/
