@clerno just anounced the stable release of C3 0.5.
Feel free to check the full list of changes: Say hello to C3 0.5 | Handmade Network
An important note is that:
From 0.5 and forward this changes: each future version will have its own branch where bug fixes will happen, but otherwise the features are frozen. New features will be reserved for the dev and master branches. Consequently, as we announce 0.5, work will actually move on to 0.6 which is where the active development will happen.
So, happy coding 
And thank you so much @clerno for your time and effort.
