Which Version To Choose

Which RTAI version should I choose?

There is a [list and description of RTAI Versions] on the Mailinglist from Jan 2005. Below you can find a list of RTAI Versions, along with their CVS tree names, Announcement emails and sometimes further information.

Currently there are two RTAI Version series developed in parallel:

• The stable series RTAI 3.x (RTAI-classic)
• RTAI Fusion: this was the experimental series, but is no more experimental since [0.9]. It is the next generation of RTAI. It improves real-time support in user-space: [Fusion: Pervasive real-time support in user-space], Attention:[Fusion is not part of RTAI any more]
