Steamhammer 1.3.2 change list. It amounts to the donated openings, 3 fixes for terran and protoss because I only tested zerg in the AIIDE version, and 2 minuscule tweaks to zerg—and of course configuration to play on SSCAIT instead of in the AIIDE tournament. Otherwise it is the same as the AIIDE version.

• New protoss openings from Antiga, donated by Iruian. Protoss play will be more varied and hopefully stronger.
• Version 1.3 had a configuration mistake, when Randomhammer rolled protoss or terran, affecting opponents Dave Churchill (UAlbertaBot) and Andrey Kurdiumov (a UAlbertaBot fork with software engineering changes rather than play changes). It was configured to always play a zerg opening, so when the bot was not zerg, the opening group was not set. Randomhammer played normally... except that it never built a combat unit. Combat units are made depending on the opening group. I corrected the configuration. Also see the next item.
• Added a workaround in case the opening group is not set to a correct value and it needs to be: Set a default opening group when the error is noticed. As it always has, it puts a message on the screen when the error is noticed, so you’ll know what’s wrong.
• The new “cancel a building if it takes too long or if too many workers are lost” feature included a bug for terran. Partly constructed buildings could be left around instead of being canceled. Fixed.
• I changed the formula for making lurkers as aux units, so that Steamhammer makes more aux lurkers. Aux units are extra units added to the regular unit mix. This should improve play when Steamhammer has lurker tech but isn’t using lurkers as a primary unit.
• If there are mutalisks, then devourers go into the flying squad with the mutalisks. They were mistakenly always put in the ground squad. It should improve devourer play, at least sometimes and a little.

Tomorrow I’ll update Steamhammer’s web page with the source. Then I will return to the opponent model.
