Dear Alerto,

Thanks for your notification. I am sad to hear that the plugin support 
will be removed.

The plugin is our company's in house program to provide a way to 
communicate between C/C++ and JavaScript, makes it possible for the 
connected primitive hardware to play some roles in the evolving Internet 

We don't use the full features of NPAPI, but just the calling/passing 
functions and information between the browser and the underneath lower 
level system/hardware resources.

If removing of the plugin is inevitable, we will need to find an 
alternative of WebKit to fulfill our goal.

Would it be possible to keep an older version of the plugin enabled 
WebKit? Like, the new WebKit would be version 3, and let the old one 
survive as WebKit 2 and stay as it is?

Thanks for your attention.
