Kobold2D v1.0.4 is available from the Kobold2D Download page!
I’m terribly sorry for the hiccup with v1.0.3. There was an absolute path causing build failures for others, which of course worked on my systems so I didn’t catch it. I retracted v1.0.3 shortly after publishing it. The fixed version is now v1.0.4. If you happen to have downloaded v1.0.3 I recommend to upgrade to v1.0.4 right away.
The most important improvements in this version are Xcode 4.3 compatibility and working around a “file not found ../libkobold2d-ios.a” issue caused by the Xcode 4 Build Location setting “Locations Specified by Targets” (in Xcode 4.3 this setting is now appropriately named “Legacy”).
