Breaking Changes

The following nodes may not be fully backward compatible with Gaea 2.1 or earlier builds.

Trees
Cellular3D
Debris
ThermalShaper (minor variance in results)

It is highly recommended that if you migrate an active project from Gaea 2.1 to 2.2, that you make a backup first and ensure all your nodes are behaving properly.

Gaea will attempt to create a Recovery copy in the Autosave folder for disaster recovery, but you should still keep a manual backup copy just in case.
