" layers property can not be animated"

Say what? What do I do now? Oh I can do this in 2.63 but what are people doing these days for moving objects off render layers?

Animate on/off renderability in outliner

Thanks I like the old way better.

Layer animation was deliberately removed, revision 51946 http://projects.blender.org/scm/viewvc.php?view=rev&root=bf-blender&revision=51946
