My latest image might have broken USB boot support due to a new version of the NASM assembler. This is fixed in the latest unstable build. Besides this the TeamViewer BLOB is fixed now (there is no directory teamviewer9 anymore in the tarball). Hivex correctly builds the ruby bindings and I based my “reset shell” tool on the new hivex library instead on chntpw. Firefox got updated to 34.0, Thunderbird to 31.3.
