In case you missed it, Enhanced 4X 1.4 has now been officially released. Thanks to all the beta testers for finding all those bugs. It should work perfectly fine with the new 1.031 patch, but if you notice anything odd report it in the bug report forums as usual.
The Enhanced 4X optional AddOns package has also returned. While only the Doubled Capitalships and Fleet Supply and Faster Combat minimods are were kept from Diplomacy (the rest will be added in later versions), there is also a new one that replace the main menu music with something a bit more familiar.
And a word about the future. Sins of a Solar Empire Rebellion patch 1.04 is due to be out by the end of July. This will be a major patch that will break saves and mods, so if you want to keep playing Enhanced 4X until a version for 1.4 is released make sure you tell steam to not automatically update the game. Hopefully it won't take too long to update but its hard to say until the patch has been released.
