See -L<http://www.unicode.org/versions/Unicode4.1.0/#NotableChanges> for the -notable changes. - -=head2 suidperl less insecure - -A pair of exploits in C<suidperl> involving debugging code have been closed. - -For new projects the core perl team strongly recommends that you use -dedicated, single purpose security tools such as C<sudo> in preference to -C<suidperl>. - -=head2 Optional site customization script - -The perl interpreter can be built to allow the use of a site customization -script. By default this is not enabled, to be consistent with previous perl -releases. To use this, add C<-Dusesitecustomize> to the command line flags -when running the C<Configure> script. See also L<perlrun/-f>. - -=head2 C<Config.pm> is now much smaller. - -C<Config.pm> is now about 3K rather than 32K, with the infrequently used -code and C<%Config> values loaded on demand. This is transparent to the -programmer, but means that most code will save parsing and loading 29K of -script (for example, code that uses C<File::Find>). - -=head1 Modules and Pragmata - -=over 4 - -=item * - -B upgraded to version 1.09 - -=item * - -base upgraded to version 2.07 - -=item * - -bignum upgraded to version 0.17 - -=item * - -bytes upgraded to version 1.02 - -=item * - -Carp upgraded to version 1.04 - -=item * - -CGI upgraded to version 3.10 - -=item * - -Class::ISA upgraded to version 0.33 - -=item * - -Data::Dumper upgraded to version 2.121_02 - -=item * - -DB_File upgraded to version 1.811 - -=item * - -Devel::PPPort upgraded to version 3.06 - -=item * - -Digest upgraded to version 1.10 - -=item * - -Encode upgraded to version 2.10 - -=item * - -FileCache upgraded to version 1.05 - -=item * - -File::Path upgraded to version 1.07 - -=item * - -File::Temp upgraded to version 0.16 - -=item * - -IO::File upgraded to version 1.11 - -=item * - -IO::Socket upgraded to version 1.28 - -=item * - -Math::BigInt upgraded to version 1.77 - -=item * - -Math::BigRat upgraded to version 0.15 - -=item * - -overload upgraded to version 1.03 - -=item * - -PathTools upgraded to version 3.05 - -=item * - -Pod::HTML upgraded to version 1.0503 - -=item * - -Pod::Perldoc upgraded to version 3.14 - -=item * - -Pod::LaTeX upgraded to version 0.58 - -=item * - -Pod::Parser upgraded to version 1.30 - -=item * - -Symbol upgraded to version 1.06 - -=item * - -Term::ANSIColor upgraded to version 1.09 - -=item * - -Test::Harness upgraded to version 2.48 - -=item * - -Test::Simple upgraded to version 0.54 - -=item * - -Text::Wrap upgraded to version 2001.09293, to fix a bug when wrap() was -called with a non-space separator. - -=item * - -threads::shared upgraded to version 0.93 - -=item * - -Time::HiRes upgraded to version 1.66 - -=item * - -Time::Local upgraded to version 1.11 - -=item * - -Unicode::Normalize upgraded to version 0.32 - -=item * - -utf8 upgraded to version 1.05 - -=item * - -Win32 upgraded to version 0.24, which provides Win32::GetFileVersion - -=back - -=head1 Utility Changes - -=head2 find2perl enhancements - -C<find2perl> has new options C<-iname>, C<-path> and C<-ipath>. - -=head1 Performance Enhancements - -The internal pointer mapping hash used during ithreads cloning now uses an -arena for memory allocation.

(This was broken in 5.8.6, and typically caused -the use of ICMP sockets to fail.) - -=item * - -Another obscure bug involving C<substr> and UTF-8 caused by bad internal -offset caching has been identified and fixed. - -=item * - -A bug involving the loading of UTF-8 tables by the regexp engine has been -fixed - code such as C<"\x{100}" =~ /[[:print:]]/> will no longer give -corrupt results. - -=item * - -Case conversion operations such as C<uc> on a long Unicode string could -exhaust memory. This has been fixed. - -=item * - -C<index>/C<rindex> were buggy for some combinations of Unicode and -non-Unicode data. This has been fixed. - -=item * - -C<read> (and presumably C<sysread>) would expose the UTF-8 internals when -reading from a byte oriented file handle into a UTF-8 scalar. This has -been fixed. - -=item * - -Several C<pack>/C<unpack> bug fixes: - -=over 4 - -=item * - -Checksums with C<b> or C<B> formats were broken. - -=item * - -C<unpack> checksums could overflow with the C<C> format. - -=item * - -C<U0> and C<C0> are now scoped to C<()> C<pack> sub-templates. - -=item * - -Counted length prefixes now don't change C<C0>/C<U0> mode. - -=item * - -C<pack> C<Z0> used to destroy the preceding character. - -=item * - -C<P>/C<p> C<pack> formats used to only recognise literal C<undef> - -=back - -=item * - -Using closures with ithreads could cause perl to crash. This was due to -failure to correctly lock internal OP structures, and has been fixed. - -=item * - -The return value of C<close> now correctly reflects any file errors that -occur while flushing the handle's data, instead of just giving failure if -the actual underlying file close operation failed. - -=item * - -C<not() || 1> used to segfault. C<not()> now behaves like C<not(0)>, which was -the pre 5.6.0 behaviour. - -=item * - -C<h2ph> has various enhancements to cope with constructs in header files that -used to result in incorrect or invalid output. - -=back - -=head1 New or Changed Diagnostics - -There is a new taint error, "%ENV is aliased to %s". This error is thrown -when taint checks are enabled and when C<*ENV> has been aliased, so that -C<%ENV> has no env-magic anymore and hence the environment cannot be verified -as taint-free. - -The internals of C<pack> and C<unpack> have been updated. All legitimate -templates should work as before, but there may be some changes in the error -reported for complex failure cases. Any behaviour changes for non-error cases -are bugs, and should be reported. - -=head1 Changed Internals - -There has been a fair amount of refactoring of the C<C> source code, partly to -make it tidier and more maintainable. The resulting object code and the -C<perl> binary may well be smaller than 5.8.6, and hopefully faster in some -cases, but apart from this there should be no user-detectable changes. - -C<${^UTF8LOCALE}> has been added to give perl space access to C<PL_utf8locale>. - -The size of the arenas used to allocate SV heads and most SV bodies can now -be changed at compile time. The old size was 1008 bytes, the new default size -is 4080 bytes. - -=head1 Known Problems - -Unicode strings returned from overloaded operators can be buggy. This is a -long standing bug reported since 5.8.6 was released, but we do not yet have -a suitable fix for it. - -=head1 Platform Specific Problems - -On UNICOS, lib/Math/BigInt/t/bigintc.t hangs burning CPU. -ext/B/t/bytecode.t and ext/Socket/t/socketpair.t both fail tests. -These are unlikely to be resolved, as our valiant UNICOS porter's last -Cray is being decommissioned. - -=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.
