Any suggestions?


Thanks for the heads up, i'll push a new release soon.


Are you going to push a new release of amalgalite soon?


yes, I was planning on implementing some of the new features in sqlite, and that hasn't happened. I'll push out a release with a minimum of changes tonight or tomorrow.
