C<package NAME VERSION> takes a strict version number. C<use +NAME VERSION> takes a lax version number. C<UNIVERSAL::VERSION> and the +L<version> object constructors take lax version numbers. Providing an +invalid version will result in a fatal error. + +These formats will be documented fully in the L<version> module in a +subsequent release of Perl 5.11. To a first approximation, a "strict" +version number is a positive decimal number (integer or decimal-fraction) +without exponentiation or else a dotted-decimal v-string with a leading 'v' +character and at least three components. A "lax" version number allows +v-strings with fewer than three components or without a leading 'v'. Under +"lax" rules, both decimal and dotted-decimal versions may have a trailing +"alpha" component separated by an underscore character after a fractional +or dotted-decimal component. + +The L<version> module adds C<version::is_strict> and C<version::is_lax> +functions to check a scalar against these rules. + +=head1 Core Enhancements + +=head2 Unicode properties + +C<\p{XDigit}> now matches the same characters as C<\p{Hex_Digit}>. This +means that in addition to the characters it currently matches, +C<[A-Fa-f0-9]>, it will also match their fullwidth equivalent forms, for +example U+FF10: FULLWIDTH DIGIT ZERO. + +=head1 Modules and Pragmata + +=head2 Pragmata Changes + +=over 4 + +=item C<less> + +Upgraded from version 0.02 to 0.03. + +This version introduces the C<stash_name> method to allow subclasses of less to +pick where in %^H to store their stash. + +=item C<version> + +Upgraded from version 0.77 to 0.81. + +This version adds support for L</Version number formats> as described earlier +in this document and in its own documentation. + +=item C<warnings> + +Upgraded from version 1.08 to 1.09. + +This version adds the C<illegalproto> warning category.

These two warnings are currently the +only ones emitted during parsing of an invalid/illegal prototype, so one +can now do + + no warnings 'illegalproto'; + +to suppress only those, but not other syntax-related warnings. Warnings where +prototypes are changed, ignored, or not met are still in the C<prototype> +category as before. (Matt S.

We're grateful to the entire CPAN +community for helping Perl to flourish. + +=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 L<http://rt.perl.org/perlbug/>. There may also be +information at L<http://www.perl.org/>, the Perl Home Page. + +If you believe you have an unreported bug, please run the B<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 +analyzed 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 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. + +=head1 SEE ALSO + +The F<Changes> file for an explanation of how to view exhaustive details +on what changed. + +The F<INSTALL> file for how to build Perl. + +The F<README> file for general stuff. + +The F<Artistic> and F<Copying> files for copyright information. + +=cut |
