 This is the Christmas release of Rakudo Perl 6. This version of the compiler
 targets the v6.c “Christmas” specification of the Perl 6 language. The
 Perl 6 community has been working toward this release over the last 15 years.
+Together, we've built a language that:
+
++ Retains the core values of Perl: expressiveness, getting the job done,
+  taking influences from natural language, and pushing the boundaries of
+  language design
++ Has clean, modern, syntax, rooted in familiar constructs but revisiting
+  and revising the things that needed it
++ Is truly multi-paradigm, enabling elegant object-oriented, functional,
+  procedural, and concurrent programming
++ Dramatically reforms and sets a new standard in regex syntax, which
+  scales up to full grammars - powerful enough to parse Perl 6 itself
++ Provides composable constructs for working with asynchronous data and
+  parallel computations
++ Values lexical scoping and encapsulation, enabling easy refactoring
++ Is extensible through meta-object programming, user-defined operators,
+  and traits
 
 The tag for this release is “коледа”[^2], a slavic word for an ancient winter
 festival that has been incorporated into Christmas. We hope you join us
