# Factor 0.67 released

## Slava Pestov — 2004-10-17 23:29:10

    Hi everybody,

    Get it from http://factor.sourceforge.net

    This release is notable because it includes the first release of the SDL

      graphics binding that is ready for wider testing. Note that the SDL

    binding only functions on the x86 architecture.

    Once you can compiled cfactor and generated an image, try running

    ./f factor.image -libraries:sdl=libSDL.so \

    	-libraries:sdl-gfx=libSDL_gfx.so

    (That should be one line.)

    Then

    "contrib/mandel.factor" run-file

    Try tweaking the file to change zoom parameters or the number of iterations.

    To see what SDL functions are supported so far, see library/sdl/, in

    particular sdl-gfx.factor and sdl-video.factor.

    If anybody manages to cook up a nice graphical demo, please post it to

    the list!

    Another notable change in this release is that cons cells are now

    immutable, and the destructive operations set-car, set-cdr, nappend and

    nreverse are gone.

    Slava
