2.71 Where is the line option in stroke method texture painting and others missing

Hey guys. I’m confused. Just downloaded 2.71. From tutorials and release notes, I see that texture painting has new options available. Among them being line and curve. When I go to stroke method, I only see the old options available. Space, dots and airbrush.

Also I saw there is a new “fill” brush available as an option as well in the new blender. I also do not see this option available in mine.

Can someone please tell me why? Am I doing something wrong? Do I need to reinstall or something?

Thank you!!

Blender 2.71 does not have these new tools, may be in blender 2.72
