How can I remove apps from my itunes library in version 11.0.0.163? The checkbox is no longer there in the new version and I do not see a drop down menu.

In the new iTunes version 11.0.0.163 I tried to delete a free app but it still shows after I deleted it from all my Apple devices. The checkbox in the previous version of iTunes does not seem to be present in the new version and I do not see a drop down menu. And there are no Help menu choices either. I guess, I will otherwise wait for the new update to iTunes as of 12.10.2012.
