Flowable upgrade from 6.4.1 to 6.8.0

Hi, I was going to upgrade Flowable from 6.4.1 to 6.8.0, Noticed that in Github release info didn’t mentioned which Spring Boot and Java version was still supported.
My current project is using Java 8 and Spring Boot 2.1.5, we don’t want a major upgrade of Java and Spring Boot version, so can I keep the same Java and Spring Boot version and just update the Flowable into 6.8.0?

Appreciate your response.
