I don't have 5.6.1 available right now, so I can't test it, but what is "%lf" doing? In 5.8.x, 'l' is a size specifier for *integers* (the "d u o x X b i D U O" formats), forcing Perl to interpret them as longs. For %f, you can use the q, L or ll size specifier (quads or long long), but not l.

As for the more general question, differences between 5.8.0 and 5.6.1 are found in the perldelta manual page that comes with 5.8.0. For 5.8.1, the differences between 5.8.0 and 5.8.1 are in its perldelta manual page (and things new in 5.8.0 are found in perl58delta.
