Today we are very pleased to announce the final release of CommandBox 4.0.0.  This has been one of our most ambitious releases and closed more than 70 tickets over 6 months of development and testing.  

This release has gone through a month of testing that created two release candidates.  A big thanks goes out to everyone who helped provide feedback.  There are a lot of new features and libraries in 4.0 as well as a major overhaul of many of the UI aspects of the CLI. 


To get the final 4.0.0 release, you can download it here from our CommandBox homepage:

Just swap out your box.exe binary and CommandBox will upgrade itself on first run.  It's a one way street, so feel free to backup the .CommandBox folder in your user home first.  

If you prefer to use Homebrew, the debian repo, or Yum repo, those are all updated now as well. 

Please Note: The box binary is normally around 38MB in size.  Due to an issue with the final build, the Pack200 process didn't run and the binary came out around 80MB.  I'll get this fixed for the next release and the binary should be back to the normal size. 


First, you'll want to read through this blog post here which details all of the new features and changed in CommandBox 4.  Note the very last section contains all of the known "breaking changes".  For the most part, CommandBox 4 is very backwards compatible.

All of the official CommandBox docs are fully updated for the 4.0.0 release.  You can find them here:

And of course, the full API docs showing all the core commands and parameters are available here:
