=head1 DESCRIPTION
This document describes differences between the 5.11.0 release and
the 5.11.1 release.
-=head1 Notice
+=head1 Incompatible Changes

-XXX Notice
+=item *
-=head1 Incompatible Changes
+The boolkeys op moved to the group of hash ops. This breaks binary compatibility.
-XXX For a release on a stable branch, this section aspires to be:
+=item *
+
+C<\s> C<\w> and C<\d> once again have the semantics they had in Perl 5.8.x.
- There are no changes intentionally incompatible with 5.XXX.XXX. If any
- exist, they are bugs and reports are welcome.
+=back
=head1 Core Enhancements
-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.
+=head2 Add C<package NAME VERSION> syntax
-=head1 New Platforms
+This new syntax allows a module author to set the $VERSION of a namespace
+when the namespace is declared with 'package'. It eliminates the need
+for C<our $VERSION = ...> and similar constructs. E.g.
-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.
+ package Foo::Bar 1.23;
+ # $Foo::Bar::VERSION == 1.23
-=head1 Modules and Pragmata
+There are several advantages to this:
-XXX All changes to installed files in F<ext/> and F<lib/> go here, in a list
-ordered by distribution name. Minimally it should be the module version,
-but it's more useful to the end user to give a paragraph's summary of the
-module's changes. In an ideal world, dual-life modules would have a
-F<Changes> file that could be cribbed.
+=over
-=head2 New Modules and Pragmata
+=item *
-=over 4
+C<$VERSION> is parsed in I<exactly> the same way as C<use NAME VERSION>
-=item C<XXX>
+=item *
-XXX
+C<$VERSION> is set at compile time
-=back
+=item *
-=head2 Pragmata Changes
+Eliminates C<$VERSION = ...> and C<eval $VERSION> clutter
-=over 4
+=item *
-=item C<XXX>
+As it requires VERSION to be a numeric literal or v-string
+literal, it can be statically parsed by toolchain modules
+without C<eval> the way MM-E<gt>parse_version does for C<$VERSION = ...>
-XXX
+=item *
+
+Alpha versions with underscores do not need to be quoted; static
+parsing will preserve the underscore, but during compilation, Perl
+will remove underscores as it does for all numeric literals
+
+It does not break old code with only C<package NAME>, but code that uses
+C<package NAME VERSION> will need to be restricted to perl 5.11.X or newer
+This is analogous to the change to C<open> from two-args to three-args.
+Users requiring the latest Perl will benefit, and perhaps N years from
+now it will become standard practice when Perl 5.12 is targeted the way
+that 5.6 is today.

+"Unicode character is illegal" has been rephrased to be more accurate

+It now reads C<Unicode non-character is illegal in interchange> and the
+perldiag documentation has been expanded a bit.

-XXX
+Perl now defaults to issuing a warning if a deprecated language feature is used.
+
+To disable this feature in a given lexical scope, you should use C<no
+warnings 'deprecated';> For information about which language features
+are deprecated and explanations of various deprecation warnings, please

+F<t/porting/podcheck.t> automatically checks the well-formedness of

-XXX Any changes specific to a particular platform. VMS and Win32 are the usual

-=head1 Obituary
+Perl 5.11.1 fails a small set of core and CPAN tests as of this release.
