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.

全部美好的事物都会走到终点，Spring Boot 1.x分支从今天（2018-07-30）开始12个月后（就是2019-08-01）就会终止维护。

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

咱们将持续不定时发布1.5.x的维护版本，一直到这个分支的终结。

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.

现有的Spring Boot 1.x 用户应该计划在这天到来以前升级到最终的2.x版本，请注意，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，也请升级JDK版本。
