Option attach-closing-while is not implemented 

I'm trying to use the --attach-closing-while astyle flag with the plugin but it doesn't work and show me this error:
**SublimeAStyleFormatter: An error occurred while formatting using astyle: [130] Invalid Artistic Style options:
attach-closing-while**

I've got that, this flag was implemented last year. There will be any update of the astyle app version used on this plugin ? @timonwong
