Bowman has released a new version, asymptote 2.22. I just imported it into TL and updated the i386-linux binary and shared files. Please (re)build it if you want to provide it and let me know. The only new issue I noted is that fftw3 was (unintentionally, I believe) required; I had to install the fftw3-devel package or there were compilation errors. Thanks, Karl
