I’m sorry for the late announcement.
We dropped Ruby 1.9.3 support on Windows (x86-mingw32 packages) since
Ruby-GNOME2 2.2.1 and rcairo 1.12.9. Because it’s hard, and Ruby core
only provide security fixes for 1.9.3 until February 23 2015, after
all support will end for 1.9.3. We highly recommend that you upgrade to
Ruby 2.1 or 2.0.0 as soon as possible.
Support for Ruby version 1.9.3 will end on February 23, 2015
