Been free for a long time. There was a post about this like 4 months ago. I think the donation for new features plan is a great idea, it helps people stay motivated to work on it with 0 risk, offers something free to those that are satisfied with the features, and makes those that want more pay for something instead of just expecting it like whiny little girls (not that i have anything against free software, i have something against people who EXPECT everything to be free)
