[coldbox-2.6.3] > [coldbox-5.0.0]

I recently migrated a ColdFusion 8 application that uses coldbox 2.6.3 to ColdFusion 11. Does anyone know where I could find the files and documentation to upgrade to coldbox 5.0.0? Any additional tips on the upgrade process is also greatly appreciated. The files I found here, https://integration.stg.ortussolutions.com/artifacts/ortussolutions/coldbox/ seems to have a lot of missing files.
