3 months ago: The io debugging functions ('vox purge', 'vox pipes', 'vox debug', and 'vox restart') have been moved from 'vox' to 'input'. (They are now 'input purge', 'input pipes', 'input debug', and 'input restart', not to be confused with 'input reset'.) This makes life easier for combat-only units who may want to remove vox for performance reasons.
