We've been publishing all stable Lucee builds and select release candidate builds to ForgeBox for some time now. This allows you to use CommandBox CLI to start up a Lucee server running the version of your choice.
server start cfengine=lucee@5.3.4.77
Publishing these CF engines has been a manual process in the past, and was something we'd do after Lucee issued a release announcement. This has changed last week now with three major additions to our process aimed at giving you faster builds, easier testing, and more deployment options.
