[support] Blocks in 4.7 : Content specific visibility settings

I just noticed the "Content specific visibility settings" area on block configuration page had disappeared. (the one that allowed to specify a block visibility according to a node type) Is there a way I can have the same functionnality : have block show up only for node pages of a given type ? I tried to use the php-mode visibility criterion, but no $node varable is available by the time the php expression is eval'd. Thanks for any suggestion. Yched
