New releases or changes for stino will be updated from the main repository
I'm currently working in a new proyect called Deviot, it's a plugin for ST2 & ST3 based in the same idea of stino but it work with platformIO as compiler, platformIO is an ecosystem who support more than ~200 boards.
The project is still in BETA but you can try it and collaborate in any way, even just using it.
