Sarg 2.2.7 failed to compile on some computers. Version 2.2.7.1 should fix that problem.
In addition, you can now change the font used to render the graphs. It will relieve those of you that are fed up with DejaVuSans.
As explained in a previous news (http://sourceforge.net/news/?group_id=68910&id=282339), the next stop is version 2.3 which is already under way.
