Ask HN: Will Bootstrap 4 be released in our lifetime?
Of course, Bootstrap 4 is still in active development, but the documentation is stale and outdated. For example, many classes have been removed or changed since Alpha 6.
Ideally, there'd be more frequent updates or an Alpha 7 so people have an easier time moving to the final version of Bootstrap 4 when it's released.
What's a good HTML/CSS/JS framework in 2017 with plenty of full-featured components and written to use flexbox by default?
