The first version of the technical paper is complete. The version at that URL is now fixed, and won't be modified. I want it to remain there to reflect my original thinking and early empirical results for zsync. I will continue to update a newer version of the paper with new results as I make changes and implement new optimisations.

I updated the paper first to reflect the improved compressed file support in zsync-0.1.2+, which had not been fuly reflected in the discussion of the implementation previously. I have also finished off the references to other projects and papers that I got ideas from.
