What do you mean by 'significant' update? Version 0.90 was released just recently, and there are continual slow and steady updates that come through. For a CSS framework, that seems quite appropriate.
I used a good bit of Bulma prior to jumping on the Tailwind train when it released. While it was a very quick way to get a nice looking page out of the box, the design choice of aggressively over-specifying selectors[0] made it incredibly frustrating to work with, especially paired with utility classes (e.g. Tachyons).
