MarsSeed [1] filed a deletion request for ruby-thin-1.5 [2]: Package is unmaintained and is not needed anymore. I have created the AUR/ruby-thin-1.6 package: https://aur.archlinux.org/packages/ruby-thin-1.6 That can satisfy the only one AUR package that needs a legacy ruby-thin, and the 1.6 version is perfectly fine for that package.
