The Latest prerelease is now out:
http://www.arcengames.com/share/AIWar1013K.zipThat version is an upgrade from version 1.012, so you have to already have 1.012 (or greater) installed. Just unzip it into your game folder (usually C:\Program Files\Arcen Games\AI War\ unless you specified something else). Please make sure that your unzip process keeps the folder structure from the zip file, rather than just unpacking all of the files into the base target directory.
What's new since 1.013J:
(Cumulative release notes since 1.012 are attached at the bottom)
-------------------
-The intermediate tutorial has been improved: wormholes are now guarded as they are in the real game, which makes scouting as hard as it should be; both group-move and the auto-building of harvesters are now mentioned in this tutorial.
-There is now a visual zoom indicator in the form of black bars at the top and bottom of the screen. These black bars get larger as the player gets further zoomed-out, thus giving an easy indicator of exactly how far out the players are zoomed. This black bar overlays the background starfield but nothing else, so it does not restrict visibility in any way (and it also is mostly behind what would typically be interface elements, anyway). This has the added effect of a nice-looking letterbox effect when very zoomed out.
-The overkill model has now been updated so that ships will still fire at enemy ships if the incoming shots will do less overkill than 2x the strength of the firing ship. This will cause 1 or 2 wasted overkill shots in a lot of battles, but will also solve a lot of the other overkill-related problems.
-Colony ships are now immune to being insta-killed, which makes capturing planets with an ion cannon on it a lot easier.
-Space docks that have a large number of "unbuildable" ships that have already hit their cap will now cycle through all of the unbuildable ship types very quickly, thus making it only around 0.5seconds less efficient than if there were no unbuildable ships in the queue at all.
-There was previously a bug that was causing planets that were destroyed to not let their ownership be later changed to nothing (this would happen if a player nuked an AI home planet and then later killed the AI). This could actually prevent players from winning. Fixed.
CHANGES FROM PAST PRERELEASES
--------------
-The efficiency improvement for shots not being drawn if too far zoomed out has been removed, as it helped very little but made it harder to see shots.
