I just did a quick test on Mac OS 10.9.5 and an incremental update from 4.5-alpha-1 to 4.5-alpha-2 worked fine (4.1 MB update). But maybe it is not working on Linux64 for some reason? I will try that tomorrow unless someone else reports their experience before I get to it.
FWIW it worked fine for me on Linux64.
