Camel 3 has been updated to document the non-existent (yet) 5.6.1. Llama 2 is independant of the underlying Perl version, since I'm just showing the basics parts of Perl, which change far less from release to release. {grin}

Llama 3 will show a few new additions like our, but nearly all the examples and exercises would have been just as home on 5.4 from two or three years ago.
