Today we released Attrio-0.4 (attributes manager for plain old Ruby objects). In this release several issues were fixed but the most significant change is that attributes defined with Attrio are inheritable. Also all class level variables were removed.

Now we can say, that all critical issues that were found and discussed in my blog (http://igor-alexandrov.github.io/blog/2013/05/23/attrio-typed-attributes-for-ruby-objects/) after the first released are fixed.
