Actually, we can't guarantee full compatibility with previous releases as many new features were introduced and several bugs fixed. Generally, we always recommend to use the latest version released. Please feel free to check our Release Notes
website, where you can find all new features, improvements and bugs fixed in Forest Pack 4.
To prevent any troubles, I would suggest you to convert your Forest objects into instances. Than it'll be possible to use that scene even on computers without Forest Pack installed. The conversion could be done by using very powerful tool which is part of Forest Pack Pro called Forest Tools
. This allows you export your scattered geometry as instances. It can be found it under Utilities
