NAME

6       perl5124delta - what is new for perl v5.12.4
7

DESCRIPTION

9       This document describes differences between the 5.12.3 release and the
10       5.12.4 release.
11
12       If you are upgrading from an earlier release such as 5.12.2, first read
13       perl5123delta, which describes differences between 5.12.2 and 5.12.3.
14       The major changes made in 5.12.0 are described in perl5120delta.
15

Incompatible Changes

17       There are no changes intentionally incompatible with 5.12.3. If any
18       exist, they are bugs and reports are welcome.
19

Selected Bug Fixes

21       When strict "refs" mode is off, "%{...}" in rvalue context returns
22       "undef" if its argument is undefined.  An optimisation introduced in
23       Perl 5.12.0 to make "keys %{...}" faster when used as a boolean did not
24       take this into account, causing "keys %{+undef}" (and "keys %$foo" when
25       $foo is undefined) to be an error, which it should be so in strict mode
26       only [perl #81750].
27
28       "lc", "uc", "lcfirst", and "ucfirst" no longer return untainted strings
29       when the argument is tainted. This has been broken since perl 5.8.9
30       [perl #87336].
31
32       Fixed a case where it was possible that a freed buffer may have been
33       read from when parsing a here document.
34

Modules and Pragmata

36       Module::CoreList has been upgraded from version 2.43 to 2.50.
37

Testing

39       The cpan/CGI/t/http.t test script has been fixed to work when the
40       environment has HTTPS_* environment variables, such as HTTPS_PROXY.
41

Documentation

43       Updated the documentation for rand() in perlfunc to note that it is not
44       cryptographically secure.
45

Platform Specific Notes

47       Linux
48           Support Ubuntu 11.04's new multi-arch library layout.

Reporting Bugs

63       If you find what you think is a bug, you might check the articles
64       recently posted to the comp.lang.perl.misc newsgroup and the perl bug
65       database at http://rt.perl.org/perlbug/ .  There may also be
66       information at http://www.perl.org/ , the Perl Home Page.
67
68       If you believe you have an unreported bug, please run the perlbug
69       program included with your release.  Be sure to trim your bug down to a
70       tiny but sufficient test case.  Your bug report, along with the output
71       of "perl -V", will be sent off to perlbug@perl.org to be analysed by
72       the Perl porting team.
73
74       If the bug you are reporting has security implications, which make it
75       inappropriate to send to a publicly archived mailing list, then please
76       send it to perl5-security-report@perl.org. This points to a closed
77       subscription unarchived mailing list, which includes all the core
78       committers, who be able to help assess the impact of issues, figure out
79       a resolution, and help co-ordinate the release of patches to mitigate
80       or fix the problem across all platforms on which Perl is supported.
81       Please only use this address for security issues in the Perl core, not
82       for modules independently distributed on CPAN.
