It's said Bootstrap5 will possible use postcss, which is great.

Hope this can be released soon, I honestly feel tired waiting for Angular2 and Bootstrap4 and I began to use something else instead(vuejs that is, stuck with Bootstrap3)

Is that 3 releases in a row where they've changed their css compiler?

It may be that changing the CSS compiler is the only change they make that's big enough to warrant changing the major version number.

Bootstrap 3 was released 3 years ago and the 4 has been on beta for 1 year now, so Bootstrap 5 will probably use something newer than postcss.

Version 4 was in development for a year when the first alpha was released, and now a year later they've released the fourth alpha version. It's not at beta yet.
