Curly braces around statements make for more readable code and help prevent bugs when you add further statements.

    for(key in config.bump) {

The variable key seems to be never declared. Assigning variables without defining them first makes them global. If this was intended, consider making it explicit like using window.key.

      gulp.src(config.bump[key]).pipe(bump({
        type: arg,
