1.0.4.14 is the latest firmware update, released 15 April, 2014.
Further, there is a whole knowledge base with plenty of articles about the RV180.

If you type "RV180" into the search bar at the top of the page, you will find detailed support documents that are meant to assist you with any questions you might have.
If these documents do not answer your questions, please post your question in this forum (Cisco Small Business Support forum) and a Cisco representative will get back to you with a response as soon as possible.
Regards,
Rocket :)
