MicroBlocks is a free (MPLv2) VM-based programming language for microcontrollers, with a graphical programming environment inspired in the Scratch and Snap! educational languages, and a virtual machine inspired in the Squeak Smalltalk-80 virtual machine.

In this talk, we present the new 2.0 version of the language and its IDE, with a completely redesigned UI, a new virtual machine with a smaller instruction footprint, lots of bug fixes, a whole new set of libraries and functionalities, and a new community-friendly translation system.
