Not much happened this week in the repository. Next to the three mentioned commits I want to point to a pull-request on which I had worked the last 1 1/2 weeks. I want to introduce with this pull request an easy and standardised way to extend mruby with C and Ruby extensions. I call it at the moment mrbgems.
Due to the reason that GitHub has introduced a new feature to emphasis contribution terms. I created a fitting file and combined the existing code conventions into it.
Masaki Muranaka added a cmake sh-elf target.
