6 perl5301delta - what is new for perl v5.30.1
7
9 This document describes differences between the 5.30.0 release and the
10 5.30.1 release.
11 If you are upgrading from an earlier release such as 5.28.0, first read
13 perl5300delta, which describes differences between 5.28.0 and 5.30.0.
14
16 There are no changes intentionally incompatible with 5.30.1. If any
17 exist, they are bugs, and we request that you submit a report. See
18 "Reporting Bugs" below.

21 Updated Modules and Pragmata
22 • Module::CoreList has been upgraded from version 5.20190522 to
23 5.20191110.

26 Changes to Existing Documentation
27 We have attempted to update the documentation to reflect the changes
28 listed in this document. If you find any we have missed, send email to
29 perlbug@perl.org <mailto:perlbug@perl.org>.
30 Additionally, documentation has been updated to reference GitHub as the
32 new canonical repository and to describe the new GitHub pull request
33 workflow.

36 • The "ECHO" macro is now defined. This is used in a "dtrace" rule
37 that was originally changed for FreeBSD, and the FreeBSD make
38 apparently predefines it. The Solaris make does not predefine
39 "ECHO" which broke this rule on Solaris. [perl #17057]
40 <https://github.com/perl/perl5/issues/17057>
41
43 Tests were added and changed to reflect the other additions and changes
44 in this release.

47 Platform-Specific Notes
48 Win32
49 The locale tests could crash on Win32 due to a Windows bug, and
50 separately due to the CRT throwing an exception if the locale name
51 wasn't validly encoded in the current code page.
52 For the second we now decode the locale name ourselves, and always
54 decode it as UTF-8.
55 [perl #16922] <https://github.com/perl/perl5/issues/16922>

59 • Setting $) now properly sets supplementary group ids, if you have
60 the necessary privileges. [perl #17031]
61 <https://github.com/perl/perl5/issues/17031>
62 • "readline @foo" now evaluates @foo in scalar context. Previously,
64 it would be evaluated in list context, and since readline() pops
65 only one argument from the stack, the stack could underflow, or be
66 left with unexpected values on it. [perl #16929]
67 <https://github.com/perl/perl5/issues/16929>
68 • sv_gets() now recovers better if the target SV is modified by a
70 signal handler. [perl #16960]
71 <https://github.com/perl/perl5/issues/16960>
72 • Matching a non-"SVf_UTF8" string against a regular expression
74 containing Unicode literals could leak an SV on each match attempt.
75 [perl #17140] <https://github.com/perl/perl5/issues/17140>
76 • "sprintf("%.*a", -10000, $x)" would cause a buffer overflow due to
78 mishandling of the negative precision value. [perl #16942]
79 <https://github.com/perl/perl5/issues/16942>
80 • scalar() on a reference could cause an erroneous assertion failure
82 during compilation. [perl #16969]
83 <https://github.com/perl/perl5/issues/16969>

86 Perl 5.30.1 represents approximately 6 months of development since Perl
87 5.30.0 and contains approximately 4,700 lines of changes across 67
88 files from 14 authors.
89 Excluding auto-generated files, documentation and release tools, there
91 were approximately 910 lines of changes to 20 .pm, .t, .c and .h files.
92 Perl continues to flourish into its fourth decade thanks to a vibrant
94 community of users and developers. The following people are known to
95 have contributed the improvements that became Perl 5.30.1:
96 Chris 'BinGOs' Williams, Dan Book, David Mitchell, Hugo van der Sanden,
98 James E Keenan, Karen Etheridge, Karl Williamson, Manuel Mausz, Max
99 Maischein, Nicolas R., Sawyer X, Steve Hay, Tom Hukins, Tony Cook.
100 The list above is almost certainly incomplete as it is automatically
102 generated from version control history. In particular, it does not
103 include the names of the (very much appreciated) contributors who
104 reported issues to the Perl bug tracker.
105 Many of the changes included in this version originated in the CPAN
107 modules included in Perl's core. We're grateful to the entire CPAN
108 community for helping Perl to flourish.
109 For a more complete list of all of Perl's historical contributors,
111 please see the AUTHORS file in the Perl source distribution.

114 If you find what you think is a bug, you might check the perl bug
115 database at <https://rt.perl.org/>. There may also be information at
116 <http://www.perl.org/>, the Perl Home Page.
117 If you believe you have an unreported bug, please run the perlbug
119 program included with your release. Be sure to trim your bug down to a
120 tiny but sufficient test case. Your bug report, along with the output
121 of "perl -V", will be sent off to perlbug@perl.org to be analysed by
122 the Perl porting team.
123 If the bug you are reporting has security implications which make it
125 inappropriate to send to a publicly archived mailing list, then see
126 "SECURITY VULNERABILITY CONTACT INFORMATION" in perlsec for details of
127 how to report the issue.

130 If you wish to thank the Perl 5 Porters for the work we had done in
131 Perl 5, you can do so by running the "perlthanks" program:
132 perlthanks
134 This will send an email to the Perl 5 Porters list with your show of
136 thanks.
