What happened on the mruby front in May 2013?
As mentioned by me last month I was proposing to introduce some kind of dependency system for GEMs. This was what I did this month by introducing version and dependency properties to the GEM specification. These specifications will be checked during the build and the build system will tell you when they can’t be satisfied.
Matz was adding Fiber support this month as a new GEM. It was quite a fight to make it work proper together with the GC.
Kimushu was sending a large pull request which introduced Word Boxing. This patch made
mrb_value a little bit more native by handling it as a word. My tests showed that this configuration is actually improving the memory usage quite a bit but I also notice that it is incompatible to NAN Boxing.
ObjectSpace support was implemented as a GEM too in this month.
Here a list with all commits during this month.
consider empty version requirements as >= 0.0.0
consider gem version to be 0.0.0 unless specified
Todo is actually already finished :-)

Added mruby-objectspace to the detault gembox.
First implementation of ObjectSpace moved outside of gc.c
ObjectSpace.count_objects was incorrectly checking if an object was already freed. Amended the count_objects test to ensure the correct distinction
Implemented ObjectSpace.count_objects to count the number of allocated objects for each type
mruby error messages should be directed to stderr
fixed a bug in initializing post mandatory block parameters
should set argc at proper position; close #1264
should have protected the return value from GC, even when the method is defined in Ruby; close #1263
remove unnecessary assignment
error in initializing callinfo stack in cipush(); close #1261
avoid unnecessary pool/syms restoration
update error message
Change fortmat to format.
mrbc: use binary mode on outfile
removed unused variables / assigns never used
remove unused local variable
Fixed the each object callback to be more consistent with other callbacks.
Changed the counting so that only objects that are alive are added to the object counts.
Minor formatting change.
Changed the each_object callback so that a pointer is passed for the object, instead of the struct.
Removed debug output
Changed the object_count so that it only iterates over the RBasic object, not the full RVALUE known by the GC
Fix compiler warning by exiting if wfp isn’t set
avoid unnecessary copy of context->filename
mrbc to take multiple files, preserving debug information if -g given; close #1243
Fix off by one issue
Add example of modifying mrbc options to add debug info
Allow mrbc command options to be changed
Fix early free of irep->filename
forgot to add src/backtrace.c
show a backtrace when when an error occurs on gem load; close #1243
move mruby’s showcallinfo into the core
Change in formatting for os_count_objects to be consistent with other functions.
Potential fix for ‘inline’ macro redefinition error – VS2012 C++

fix regexp warning: character class has duplicated range
[doc] Add minimal build configuration
Move declaration of kernel to the beginning of the method
mirb should handle exception from inspect; close #1238

remove explicit check to honor duck typing
avoid subclassing Array not to inherit too much methods
