Heh, well, it seems I'm destined to always release a hot fix after every regular build for something or other
Brought it upon myself this time because I knew it's generally a bad idea to add a big new feature too close to a release (like, the evening before...) without enough time to fully test it.
Still, I don't regret it because forcing myself to go through with it means we have this cool new feature to play with
(Saves are compatible with Alpha 5--all that changed was one line in the source :/)
The "full" Alpha 5b (0.10.151217b) changelog:* FIX: Smart auto-replacement of parts might choose incorrectly in swaps involving three or more of the same item with different integrity values [zxc]
For the real changelog regarding all the latest goodies, see the previous announcement.
