 perl5124delta - what is new for perl v5.12.4

DDEESSCCRRIIPPTTIIOONN #

 This document describes differences between the 5.12.3 release and the
 5.12.4 release.

 If you are upgrading from an earlier release such as 5.12.2, first read
 perl5123delta, which describes differences between 5.12.2 and 5.12.3. The
 major changes made in 5.12.0 are described in perl5120delta.

IInnccoommppaattiibbllee CChhaannggeess There are no changes intentionally incompatible with 5.12.3. If any exist, they are bugs and reports are welcome.

SSeelleecctteedd BBuugg FFiixxeess When strict “refs” mode is off, “%{…}” in rvalue context returns “undef” if its argument is undefined. An optimisation introduced in Perl 5.12.0 to make “keys %{…}” faster when used as a boolean did not take this into account, causing “keys %{+undef}” (and “keys %$foo” when $foo is undefined) to be an error, which it should be so in strict mode only [perl #81750].

 "lc", "uc", "lcfirst", and "ucfirst" no longer return untainted strings
 when the argument is tainted. This has been broken since perl 5.8.9 [perl
 #87336].

 Fixed a case where it was possible that a freed buffer may have been read
 from when parsing a here document.

MMoodduulleess aanndd PPrraaggmmaattaa Module::CoreList has been upgraded from version 2.43 to 2.50.

TTeessttiinngg The _c_p_a_n_/_C_G_I_/_t_/_h_t_t_p_.t test script has been fixed to work when the environment has HTTPS* environment variables, such as HTTPS_PROXY.

DDooccuummeennttaattiioonn Updated the documentation for rraanndd(()) in perlfunc to note that it is not cryptographically secure.

PPllaattffoorrmm SSppeecciiffiicc NNootteess Linux Support Ubuntu 11.04’s new multi-arch library layout.

AAcckknnoowwlleeddggeemmeennttss Perl 5.12.4 represents approximately 5 months of development since Perl 5.12.3 and contains approximately 200 lines of changes across 11 files from 8 authors.

 Perl continues to flourish into its third decade thanks to a vibrant
 community of users and developers.  The following people are known to
 have contributed the improvements that became Perl 5.12.4:

 Andy Dougherty, David Golden, David Leadbeater, Father Chrysostomos,
 Florian Ragwitz, Jesse Vincent, Leon Brocard, Zsbán Ambrus.

RReeppoorrttiinngg BBuuggss 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://rt.perl.org/perlbug/ . 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 ppeerrllbbuugg 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 "perl
 -V", will be sent off to perlbug@perl.org to be analysed by the Perl
 porting team.

 If the bug you are reporting has security implications, which make it
 inappropriate to send to a publicly archived mailing list, then please
 send it to perl5-security-report@perl.org. This points to a closed
 subscription unarchived mailing list, which includes all the core
 committers, who be able to help assess the impact of issues, figure out a
 resolution, and help co-ordinate the release of patches to mitigate or
 fix the problem across all platforms on which Perl is supported. Please
 only use this address for security issues in the Perl core, not for
 modules independently distributed on CPAN.
