Blender 2.8 is now rocking a fully fledged 2D Animation pipeline with the complete rewrite of the Grease Pencil system. This is a round-up of the main features you'll find when playing around, but it's such a big project that I didn't even managed to cover everything like the animation editors or materials. Go explore your own 3̶D̶ 2D+3D software!
Congratulations to the Grease Pencil team: Antonio Vazquez, Joshua Leung, Daniel Martinez Lara, Matias Mendiola.
