This Saturday, 2013-02-02, the first update to RMagick in nearly three years was released: 2.13.2
One of the most useful changes is support for ImageMagick 6.8 (pull request), the current version from brew. If you're unable to upgrade RMagick, but must use ImageMagick 6.8, there is a workaround here.
The changelog for 2.13.2 also mentions support for ruby 1.9.3, but my project's still on 1.8.7 for now so I can't confirm that.
From all the ruby devs whose projects depend on RMagick, here's a big thanks to the maintainers.
