[Jul.Aug.Sep 2013] mruby news

What happened on the mruby front from July to September 2013?

Improve Core and Standard Library

The mruby-toplevel-ext GEM was added to the default GEMBox and the new mruby-exit GEM was created. The Exception class got the new method backtrace. And finally Object#instance_exec was implemented.

Refactoring

Several parts of the C API were refactored (i.e. Class, Array, String and Range).

Test Refactoring

After the big test refactoring in June 2013, more improvements to individual test cases were performed.

Garbage Collector

A large amount of commits from Fleurer were targeted at the Garbage Collector. Mainly refactoring and documentation work, but also several bugs and API improvements were done.
