Updating to new v4 versions

The new v4 toolkit offers a great method for updating v3 scripts to v4 (Convert-ADTDeployment). Is there a similar method for updating v4 scripts to newer versions? (e.g. updating from script version 4.0.5 to 4.0.6)

I use Winmerge on the front script (aka Invoke-AppDeployToolkit.ps1) and the Config.psd1.
I compare the old and new versions and copy the lines from the old into the new files. Sometimes nothing really changes between versions on those files.

I’ve been doing this with PSADT 3.x for years.
