 ## Features/Improvements
 
-* **[Engine]** Support for DCS 2.8.3.37556.
+* **[Engine]** Support for DCS 2.8.4.39731.
 * **[Engine]** Saved games are now a zip file of save assets for easier bug reporting. The new extension is .liberation.zip. Drag and drop that file into bug reports.
 * **[Campaign]** Added options to limit squadron sizes and to begin all squadrons at maximum strength. Maximum squadron size is defined during air wing configuration with default values provided by the campaign.
 * **[Campaign AI]** Added an option to instruct the campaign AI to prefer fulfilling missions with squadrons which have a matching primary task. Previously distance from target held a stronger influence than task preference. Primary tasks for squadrons are set by campaign designers but are user-configurable.
