07197c45
RS
110As of 5.18.0, Perl on VMS can (at last) be built in and installed from a
111directory having dots in the name, so it is no longer necessary to rename the
112top-level source directory before building.

07197c45
RS
114The pertinent instructions have been removed from README.vms, so we also no
115longer need to update the version number that was embedded in those
116instructions.

9f351b45 127
07197c45
RS
128After some changes earlier in 5.17, C<split>'s behavior has been simplified: if
129the PATTERN argument evaluates to a literal string containing one space, it is
130treated the way that a I<literal> string containing one space once was.

7cf3104f 133
07197c45
RS
134C<(?{…})> and C<qr> constant overloading did not play nicely together, and when
135C<qr> constant overloading was in effect, C<qr> constructs inside a C<(?{…})>
136construct were incorrectly interpreted. [perl #116823]

142Perl 5.17.11 represents approximately 4 weeks of development since Perl 5.17.10
143and contains approximately 3,800 lines of changes across 130 files from 17
144authors.
145
146Perl continues to flourish into its third decade thanks to a vibrant community
147of users and developers. The following people are known to have contributed the
148improvements that became Perl 5.17.11:
149
150Aaron Crane, Andy Dougherty, Brian Fraser, Chris 'BinGOs' Williams, Craig A.
151Berry, David Mitchell, François Perrad, James E Keenan, Jan Dubois, Karl
152Williamson, Leon Timmermans, Max Maischein, Moritz Lenz, Nicholas Clark,
153Ricardo Signes, Tony Cook, Yves Orton.

155The list above is almost certainly incomplete as it is automatically generated
156from version control history. In particular, it does not include the names of
157the (very much appreciated) contributors who reported issues to the Perl bug
158tracker.
159
160Many of the changes included in this version originated in the CPAN modules
161included in Perl's core. We're grateful to the entire CPAN community for
162helping Perl to flourish.

169If you find what you think is a bug, you might check the articles recently
170posted to the comp.lang.perl.misc newsgroup and the perl bug database at
171http://rt.perl.org/perlbug/ . There may also be information at
172http://www.perl.org/ , the Perl Home Page.

174If you believe you have an unreported bug, please run the L<perlbug> program
175included with your release. Be sure to trim your bug down to a tiny but
176sufficient test case. Your bug report, along with the output of C<perl -V>,
177will be sent off to perlbug@perl.org to be analysed by the Perl porting team.

179If the bug you are reporting has security implications, which make it
e08634c5
SH
180inappropriate to send to a publicly archived mailing list, then please send it
181to perl5-security-report@perl.org. This points to a closed subscription
182unarchived mailing list, which includes all the core committers, who will be
183able to help assess the impact of issues, figure out a resolution, and help
f9001595 184co-ordinate the release of patches to mitigate or fix the problem across all
e08634c5
SH
185platforms on which Perl is supported. Please only use this address for
186security issues in the Perl core, not for modules independently distributed on
187CPAN.
