All changes of the 'ktbl' package are commited at once to take away the pressure from you.
You are under high pressure to finish your dissertation. That is enough till mid of march.
In the meantime I have switch from Java 6 to Java 7 and implemented some new Java 7 features in the 'ktbl' package (the diamond operator for example). The other packages will follow soon. This is not very dramatic but the source code won't compile under Java 6.
