+perl5114delta - what is new for perl v5.11.4
=head1 DESCRIPTION
L<perl5113delta>, which describes differences between 5.11.2 and
5.11.3.
-=head1 Notice
-
-XXX Any important notices here
-
=head1 Incompatible Changes
-XXX For a release on a stable branch, this section aspires to be:
+=head2 Version number formats
- There are no changes intentionally incompatible with 5.XXX.XXX. If any
- exist, they are bugs and reports are welcome.
+Acceptable version number formats have been formalized into "strict" and
+"lax" rules. 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.
-=head1 Core Enhancements
+The L<version> module adds C<version::is_strict> and C<version::is_lax>
+functions to check a scalar against these rules.
-XXX New core language features go here. Summarise user-visible core language
-enhancements. Particularly prominent performance optimisations could go
-here, but most should go in the L</Performance Enhancements> section.
+=head1 Core Enhancements
=head2 Unicode properties
C<[A-Fa-f0-9]>, it will also match their fullwidth equivalent forms, for
example U+FF10: FULLWIDTH DIGIT ZERO.
-=head1 New Platforms
+=head1 Modules and Pragmata
-XXX List any platforms that this version of perl compiles on, that previous
-versions did not. These will either be enabled by new files in the F<hints/>
-directories, or new subdirectories and F<README> files at the top level of the
-source tree.
+=head2 Pragmata Changes
-=head1 Modules and Pragmata
+=over 4
-XXX All changes to installed files in F<cpan/>, F<dist/>, F<ext/> and F<lib/>
-go here. If Module::CoreList is updated, generate an initial draft of the
-following sections using F<Porting/corelist-perldelta.pl>, which prints stub
-entries to STDOUT. Results can be pasted in place of the '=head2' entries
-below. A paragraph summary for important changes should then be added by hand.
-In an ideal world, dual-life modules would have a F<Changes> file that could be
-cribbed.
