- 2015.08.19 – Bootstrap 4 alpha 1
- 2015.12.08 – Bootstrap 4 alpha 2
- 2016.07.27 – Bootstrap 4 Alpha 3
官方也有說到
The general development and release plan looks something like this:
- A few alpha releases while things are still in flux.
- Two beta releases after features and functionality are locked down to really test things out.
- Two release candidates (RCs) to really test things out closer to production environments.
- Then, the final release!
看起來應該還要一陣子
有去issue看了一下資料
現在正在close alpha 4的issue
後面還會有alpha 5跟alpha 6
之後應該就會接beta 1、beta 2
還有RC1、RC2
照舊有的紀錄推斷，正式release可能是明年年底，到後年年中之間吧
