Yes, it's true. Config::Tiny now allows you to assign an array of values to a key.
Various examples are documented there and in test files. Sample usage:

[section]
greetings[]=Hello
greetings[]=World!
one=two
Foo=Bar

Note: The 2 lines of greetings can be separated by other lines too.

You access these values like this:
say $Config->{section}->{greetings}->[0];
say $Config->{section}->{greetings}->[1]
