A major upgrade was given to the Grease Pencil tool, which inter alia brought the ability to edit and animate strokes. The first developments from the Gooseberry Project like a Sequencer Backdrop, Cycles viewport world background and others were added. Cycles got various improvements and speedups, as well as support for cameras inside volumes, the UI got a new 'minimalistic' fullscreenmode and Input Method Editor support for textbuttons (used for complex Chinese and Japanese character input), the Knife-tool was improved, Freestyle got a SVG exporter, and many more features which are worth checking out!
