Arename version 4.0 will hit Debian's sid mirrors soon (as 4.0-2).

Maximilian Gaß stepped down as arename's Debian maintainer. So, let me take the time to thank him for getting the program into Debian and maintaining the package for as long as he did. Thank you.

Seems like Debian's Perl Group has adopted the package and gregor herrmann uploaded an updated package earlier tonight. So it'll be available in the mirrors tomorrow-ish. Thanks, gregor.
