Version 2.5

Up until September 2011, qcircuit existed as a .tex file which users could compile concurrently with their own source files. The numbering scheme for those releases counted up to 2.0. This current release generates a (semi) backwards-incompatible jump; namely, we move to a .sty file and introduce some prespecified options. Users familiar with the original QCircuit.tex file and structure will need to read the documentation and/or the Qtutorial.tex file to understand how to call and use qcircuit.

However, as the underlying graphics engine remains xy-pic, I felt it imprudent to move to a version 3.0. We will begin using that version number upon rewriting qcircuit based on a different graphics engine.
