Bare Bones Software today announced a free “T-shirt upgrade” to be held at next week’s Macworld Conference & Expo in San Francisco. Bones T-shirt will receive a brand-new “BBEdit 8: Habit-forming” shirt for free while supplies last. “Bare Bones Software T-shirts, like our finely crafted software, require periodic revision and updates,” said Rich Siegel, founder and CEO of Bare Bones. “Now is the perfect opportunity to upgrade or just add to your collection. So don’t forget to pack your old shirt!”
