No, it doesn't. Perl "6" is dead, now a new language called Raku. The major version jump to 7 is partly to get past that confusion.

To quote the announcement on perl.com:

Why 7 and not 6?

There are two parts to this answer. First, “Perl 6” was already taken by what is now known as Raku. A long time ago, we thought that a very ambitious rewrite effort would replace v5.8. In short, that’s not what happened and the language has gone on to live a life of its own.

So, 7 was the next available number. That’s it. It’s just the next cardinal number in line.

Hope this helps!
