Dear All,

QCA package version 1.0-4 has been released today, the sources are now visible on CRAN and the binaries for Windows and MacOS should appear in a couple of more days.

We highly recommend upgrading to this version. Apart from a number of small bug fixes, the most notable reason to upgrade is a dramatic increase in speed, due to the compilation of some computationally intensive parts of the code in the C language. QCA is now faster by a factor of at least 10 (in some cases over 100), and it consumes considerably less memory.

We are grateful to Jim Holtman, Simon Urbanek, Duncan Murdoch, Martin Morgan and Prof. Brian Ripley for very useful hints while optimizing both the R code and some of its C implementation.

Best wishes,
Adrian and Alrik
