Version 1.2.1 released

Version 1.2.1 has been released!

This version contains very minor fixed so that compilation doesn't fail for recent versions of Ubuntu (and likely other platforms with recent compiler updates). There are still some outstanding issues in the tracker related to an unusual Objective-C behavior observed by one user. Once that is fixed and I do some cleaning (like either fixing or purging that slisp example for once and for all), I'll update to 1.3.

Let me know if there are any problems with the release - this is the first time I've used the updated file release system and could have done something wrong....
