> <\body> It is difficult to give a precise roadmap for the development, because our plans are permanently adjusted as a function of unexpected needs, help by new contributors and personal moods. Nevertheless, we tend to spend a significant time on a few major objectives, while amusing ourselves with the implementation of a few new features. Roughly speaking, our roadmap can therefore be divided into three major parts: <\enumerate> A limited number of major objectives for the upcoming stable versions (2.1 and 2.2). A certain number of minor objectives, subject to continuous changes, and which progress as a function of available time. Other projects, which are developed by external contributors, but which occasionnaly require changes in the core. <\traverse> >
