New Stuff

Here's some highlights of this release:

Java 14 support

Java 14 is now supported in CommandBox 5.1.0.  In order to support Java 14, we had to stop using Pack200 which means the binary sizes have grown a little.  The good news is CommandBox will start up a little faster on its first run since there's less to unpack now.

Start pure HTML Server

You can start up a lightweight server that only serves static files now with CommandBox.  

server start cfengine=none

New CommandBox Light and CommandBox Thin Binaries

In pursuit of the smallest possible Docker images, we have CommandBox light which is built on Lucee Light.  We also have a box "thin" binary you can swap out with the full self-extracting binary when using CommandBox in custom docker images.  Check out Pete Freitag's Minibox image to see both of these in use in a super tiny 78 Meg docker image.  More docs here:

Force working directory when starting

If you're using box in an integration where you want it to start up in a specific working directory, there is a new bootstrap CLI arg for that.

box -cliworkingDir=C:/my/path/here/

Server tray menu item custom commands

You've always been able to specify custom menu items in your server.json or global config settings, but we've kicked it up a notch.  Not only can you contribute to existing sub menus now, you can execute arbitrary native commands synchronously or async.

    "trayOptions" : [
            "label" : "Does the Internet work?",
            "action" : "run",
            "command" : "ping"
            "label" : "Math is math!",
            "action" : "runAsync",
            "command" : "calc.exe"
            "label" : "Update dependencies",
            "action" : "runTerminal",
            "command" : "box update"

HTML only server is sweet!

Yep, we got tired of having to touch Node just to spin up a simple server. I did some tests, and the HTML-only server can run pretty well on very small heap sizes like 64MB.
