All good things must come to an end, and for the 1.x line of Spring Boot that means we will need to cease maintenance twelve months from today, on Aug 1st 2019.

全部美好的事物都會走到終點，Spring Boot 1.x分支從今天（2018-07-30）開始12個月後（就是2019-08-01）就會終止維護。

We will keep publishing occasional 1.5.x maintenance releases up until that point and will then end the branch.

咱們將持續不定時發佈1.5.x的維護版本，一直到這個分支的終結。

Existing Spring Boot 1.x users should plan accordingly to ensure that they have upgraded to the latest 2.x version before that date. Please also note that Spring Boot 2.0 and above requires Java 8+, so if you’re running Java 6 or 7 you should also plan on upgrading your JDK.

現有的Spring Boot 1.x 用戶應該計劃在這天到來以前升級到最終的2.x版本，請注意，Spring Boot 2.0及以上版本要求Java 8+, 所以，若是大家正在使用Java 6 或7，也請升級JDK版本。
