--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.
++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 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.
++Feel free to drop a note if a certain breaking change is breaking your mod and you have difficulties finding a way to work around the issue.
  {{note}}
--The list of breaking changes does **NOT** cover changes in the provided/shipped Lua scripts (for instance the ones located under ui/addons/XXX or ui/core/Lua. These scripts can change anytime without explicit notice. If you hook into one of these scripts or provide replacements for these, please check the script for possible breaking changes yourself.

--Further note that the list provides information about breaking changes which are in the pipeline of being released. This is meant merely as an informational heads up. Neither do mistake this as an announcement of that version becoming available soon nor take it as a fact that such a change will go live. Any information provided for not yet released versions can change (and even be removed) prior to such version having seen the light of day.

++As a final note, please be aware that issues introduced during the beta phase might not be explicitly mentioned in the list below, if things would only be broken in-between two beta versions. While we still aim to document any (potential) breaking change here, there might be circumstances for which we divert from that procedure (especially in case of only minor issues which are considered merely bugfixes rather than an intended behavior change).

--{{warning title="UI modding considered unstable"}}
++{{warning title="UI modding considered unstable until further notice..."}}
  Please note that UI modding must be considered **unstable** in the current version. While we are working hard to get the UI modding integration into a stable state, we might have to introduce larger backwards incompatibilities in the following patches. This means that you might have to modify any mod using UI modding capabilities to a larger extend to keep it compatible with certain patches. Still, we are doing our best not to unnecessarily break things for modders and certainly will announce such changes on this page here.
