3f01b192 16
07197c45 17Although no major incompatibilities have been introduced, the "switch" family
be07ea8f 18of features have been marked experimental and will now emit warnings. These
07197c45 19are: the C<~~> operator, C<given>, and C<when>.

82d98f72 76
07197c45
RS
77As of 5.18.0, Perl on VMS can (at last) be built in and installed from a
78directory having dots in the name, so it is no longer necessary to rename the
79top-level source directory before building.

RS
81The pertinent instructions have been removed from README.vms, so we also no
82longer need to update the version number that was embedded in those
83instructions.

9f351b45 94
07197c45
RS
95After some changes earlier in 5.17, C<split>'s behavior has been simplified: if
96the PATTERN argument evaluates to a literal string containing one space, it is
97treated the way that a I<literal> string containing one space once was.

7cf3104f 100
07197c45
RS
101C<(?{…})> and C<qr> constant overloading did not play nicely together, and when
102C<qr> constant overloading was in effect, C<qr> constructs inside a C<(?{…})>
103construct were incorrectly interpreted. [perl #116823]

113Perl continues to flourish into its third decade thanks to a vibrant community
114of users and developers. The following people are known to have contributed the

122The list above is almost certainly incomplete as it is automatically generated
123from version control history. In particular, it does not include the names of
124the (very much appreciated) contributors who reported issues to the Perl bug
125tracker.
126
127Many of the changes included in this version originated in the CPAN modules
128included in Perl's core. We're grateful to the entire CPAN community for
129helping Perl to flourish.

136If you find what you think is a bug, you might check the articles recently
137posted to the comp.lang.perl.misc newsgroup and the perl bug database at
138http://rt.perl.org/perlbug/ . There may also be information at
139http://www.perl.org/ , the Perl Home Page.

141If you believe you have an unreported bug, please run the L<perlbug> program
142included with your release. Be sure to trim your bug down to a tiny but
143sufficient test case. Your bug report, along with the output of C<perl -V>,
144will be sent off to perlbug@perl.org to be analysed by the Perl porting team.

146If the bug you are reporting has security implications, which make it
e08634c5
SH
147inappropriate to send to a publicly archived mailing list, then please send it
148to perl5-security-report@perl.org. This points to a closed subscription
149unarchived mailing list, which includes all the core committers, who will be
150able to help assess the impact of issues, figure out a resolution, and help
f9001595 151co-ordinate the release of patches to mitigate or fix the problem across all
e08634c5

152platforms on which Perl is supported. Please only use this address for
153security issues in the Perl core, not for modules independently distributed on
