What happened on the mruby front in October 2013?

Implementation

The following methods were re-implemented in Ruby and their C implementation was removed:

Class.new was improved and accepts now a block. And the following stuff was newly implemented:

Bugfixes

Some work was done to fix a bug which occur when two files are concatenated to each other. A possible overflow of Fixnum#succ was prevented. And an issue with multi-line strings in the mirb is now catched.

Improve Test Coverage

Some regression tests were added for previous bugfixes. This is something we miss quite a lot. Many bugfixes are provided without regression tests, this might lead in the future to the situation that the same bug appears again without us noticing. So lets write more regression tests!
