Our goal is to keep breaking changes between any given version of X4 to an absolute minimum. In some cases, however, we have had to change things which break scripts/mods which were written for older versions.
The following table provides an overview about all breaking changes. This should help you to make any necessary changes to restore compatibility of older mods with new versions of X4.
Please note that issues introduced during the beta phase might not be explicitly mentioned as a breaking change, if things would only be broken in-between two beta versions.
The following pages list all breaking changes related to UI modding.
