[guardian-dev] Pixelknot v0.3-rc1

Fri Apr 26 08:35:23 EDT 2013

The build your running now is a debug build, whereas I think the
previous was a release build.

It is possible that could explain the discrepancy. I suppose I should
upload a release build instead, since that's closer to the actual build
that users will get.
