How are you building the images for Docker Hub?

I just checked out the flowable-release-6.4.1 branch:

git clone -b flowable-release-6.4.1 https://github.com/flowable/flowable-engine.git

And noticed that the all-in-one Dockerfile refers to Tomcat v8.5.34

However, the all-in-one image on Docker Hub (tagged 6.4.1) refers to Tomcat v8.5.37

51

Even the master branch (6.5.0-SNAPSHOT) refers to Tomcat v8.5.34

The last commit in the docker directory was 2 Oct 2018:
