+
+perl51710delta - what is new for perl v5.17.10
+
+=head1 DESCRIPTION
+
+This document describes differences between the 5.17.9 release and the 5.17.10
+release.
+
+If you are upgrading from an earlier release such as 5.17.8, first read
+L<perl5179delta>, which describes differences between 5.17.8 and 5.17.9.
+
+=head1 Security
+
+=head2 Hash iteration randomized per hash variable
+
+Every hash has its own iteration order, which
+should make it much more difficult to determine what the current hash
+seed is.
+
+=head1 Incompatible Changes
+
+=head2 Explicit rules for variable names and identifiers
+
+Due to an oversight, length-one variable names in 5.16 were completely
+unrestricted, and opened the door to several kinds of insanity. As of
+5.18, these now follow the rules of other identifiers, in addition
+to accepting characters that match the \p{POSIX_Punct} property.
+
+There are no longer any differences in the parsing of identifiers specified
+as $... or ${...}; previously, they were dealt with in different parts of
+the core, and so had slightly different behavior. For instance,
+C<${foo:bar}> was a legal variable name. Since they are now both parsed
+by the same code, that is no longer the case.
+
+[ List each incompatible change as a =head2 entry ]

+
+=head2 PL_sv_objcount
+
+This interpreter-global variable used to track the total number of
+Perl objects in the interpreter. It is no longer maintained and will
+be removed altogether in Perl 5.20.

+
+The new copy-on-write mechanism that was introduced in 5.17.7 has now been

+default for 5.20.
+
+This change also re-enables PL_sawampersand by default.
+
+It can be enabled in a perl build by running F<Configure> with
+B<-Accflags=-DPERL_NEW_COPY_ON_WRITE>, and we would encourage XS authors to
+try their code with such an enabled perl, and provide feedback.

+=head1 Acknowledgements
+
+Perl 5.17.10 represents approximately 4 weeks of development since Perl 5.17.9
+and contains approximately 77,000 lines of changes across 440 files from 42
+authors.
+
+Perl continues to flourish into its third decade thanks to a vibrant community
+of users and developers. The following people are known to have contributed the
+improvements that became Perl 5.17.10:
+
+Aaron Crane, Aaron Trevena, Andrew Tam, Andy Dougherty, Anton Nikishaev, Brad
+Gilbert, Brian Fraser, Charlie Gonzalez, Chris 'BinGOs' Williams, Craig A.
+Berry, Daniel Dragan, David Golden, David Mitchell, Dominic Hargreaves, Florian
+Ragwitz, George Greer, H.Merijn Brand, James E Keenan, Jasmine Ahuja, John
+Goodyear, John Peacock, Karl Williamson, Kent Fredric, Lukas Mai, Max
+Maischein, Nicholas Clark, Patrik Hägglund, Paul Green, Peter Martini, Rafael
+Garcia-Suarez, Renee Baecker, Ricardo Signes, Ruslan Zakirov, Salvador
+Fandiño, Scott Lanning, Shirakata Kentaro, Steffen Müller, Steve Hay, Steve
+Peters, Sullivan Beck, Tony Cook, Yves Orton.
+
+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 F<AUTHORS> file in the Perl source distribution.
+
+=head1 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 L<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 C<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.

-Use of C<@*>, C<&*>, C<**> or C<%*> is now deprecated, and will generate a
-compile time warning, enabled by default. In future such code will fail to
-compile with a syntax error. Removing these variables, along with C<$*>,
-will permit future syntax additions.

-
-The warning that use of C<$*> and C<$#> is no longer supported is now
-generated for every location that references them. Previously it would fail
-to be generated if another variable using the same typeglob was seen first
-(e.g. C<@*> before C<$*>), and would not be generated for the second and
-subsequent uses. (It's hard to fix the failure to generate warnings at all
-without also generating them every time, and warning every time is
-consistent with the warnings that C<$[> used to generate.)

-The new copy-on-write mechanism that was introduced in 5.17.7 has now been
-disabled by default, since it was felt that there were too many rough
-edges for the 5.18 release. It is expected that it will be enabled by
-default for 5.20.
+XXX
-This change also re-enables PL_sawampersand by default.
+=back
-It can be enabled in a perl build by running F<Configure> with
-B<-Accflags=-DPERL_NEW_COPY_ON_WRITE>, and we would encourage XS authors to
-try their code with such an enabled perl, and provide feedback.
-XXX need blurb, e.g. a reference to a new section in perlguts or perlxs
-explaining how XS authors should handle COW strings.
+=head1 Known Problems

+XXX Descriptions of platform agnostic bugs we know we can't fix go here. Any
+tests that had to be C<TODO>ed for the release would be noted here. Unfixed
+platform specific bugs also go here.
