Version 6 is a near complete rewrite of Terra; more changes were made during 6.0 development than the entirety of Terra development prior. Here's a short overview of the changes:
* Addon API was completely separated from common implementations
* Addon loader was rewritten to use "bootstrap addons" to define loading process
* Config schemas are now implemented by "core addons" bundled with platform distributions
* Brand new overworld config
You can see a full list of changes in the [6.0 tracking Pull Request](https://github.com/PolyhedralDev/Terra/pull/227).
You can read more about the new API at the [new Terra wiki](https://terra.polydev.org)
