NAME
perl5184delta - what is new for perl v5.18.4
DESCRIPTION
This document describes differences between the 5.18.4 release and the
5.18.2 release. Please note: This document ignores perl 5.18.3, a
broken release which existed for a few hours only.
If you are upgrading from an earlier release such as 5.18.1, first read
perl5182delta, which describes differences between 5.18.1 and 5.18.2.
Modules and Pragmata
Updated Modules and Pragmata
o Digest::SHA has been upgraded from 5.84_01 to 5.84_02.
o perl5db.pl has been upgraded from version 1.39_10 to 1.39_11.
This fixes a crash in tab completion, where available. [perl
#120827] Also, filehandle information is properly reset after a
pager is run. [perl #121456]
Platform Support
Platform-Specific Notes
Win32
o Introduced by perl #113536
<https://rt.perl.org/Public/Bug/Display.html?id=113536>, a
memory leak on every call to "system" and backticks (" `` "),
on most Win32 Perls starting from 5.18.0 has been fixed. The
memory leak only occurred if you enabled pseudo-fork in your
build of Win32 Perl, and were running that build on Server 2003
R2 or newer OS. The leak does not appear on WinXP SP3. [perl
#121676
<https://rt.perl.org/Public/Bug/Display.html?id=121676>]
Selected Bug Fixes
o The debugger now properly resets filehandles as needed. [perl
#121456]
o A segfault in Digest::SHA has been addressed. [perl #121421]
o perl can again be built with USE_64_BIT_INT, with Visual C 2003, 32
bit. [perl #120925]
o A leading { (brace) in formats is properly parsed again. [perl
#119973]
o Copy the values used to perturb hash iteration when cloning an
interpreter. This was fairly harmless but caused "valgrind" to
complain. [perl #121336]
o In Perl v5.18 "undef *_; goto &sub" and "local *_; goto &sub"
started crashing. This has been fixed. [perl #119949]

The list above is almost certainly incomplete as it is automatically
generated from version control history. In particular, it does not
include the names of the (very much appreciated) contributors who
reported issues to the Perl bug tracker.
Many of the changes included in this version originated in the CPAN
modules included in Perl's core. We're grateful to the entire CPAN
community for helping Perl to flourish.
For a more complete list of all of Perl's historical contributors,
please see the AUTHORS file in the Perl source distribution.
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://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 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 "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 will 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.
