Roller 6.0.0-SNAPSHOT
Upgraded this site to Roller 6.0.0-SNAPSHOT today, which meant an hour of fiddling around with my private Docker registry, then giving up and using the one free private repository offered by DockerHub and then, another hour of futzing around trying to figure out my PostgreSQL JDBC driver doesn't work anymore (I inadvertently upgraded from JDK 1.7 to 1.8) and why I can't seem to upgrade it (Kubernetes caches Docker images unless you set imagePullPolicy to always). In the end, I got it working. This post is written in the yet to be officially release Apache Roller 6.0.0-SNAPSHOT version.
Side note: the new rich-text editor in Roller is now Summernote and it seems quite nice. I need to tweak it a bit because there is currently no way to set the font or add a link unless you switch to raw HTML mode.
