@itemize
@item OpenGL backend (@command{--backend glx}), in addition to the old X Render
backend.
@item Inactive window transparency (@command{-i}) and dimming
(@command{--inactive-dim}).
@item Menu transparency (@command{-m}, thanks to Dana).
@item Shadows are now enabled for argb windows, e.g terminals with transparency
@item Removed serverside shadows (and simple compositing) to clean the code,
the only option that remains is clientside shadows.
@item Configuration files (see the man page for more details).
@item Colored shadows (@command{--shadow-[red/green/blue]}).
@item A new fade system.
@item VSync support (not always working).
@item Blur of background of transparent windows, window color inversion (bad in
performance).
@item Some more options...
