Sub Folder Picker - new functions

I am a new user, licensed from V 1.9.263. I have upgraded to the latest Version 1.9.267.0. I'm unable to locate the new functions (V.265 to V.267) relating to Sub Folder Picker (the Picker Pane, "Image Folder" link and integration with Windows 7 Task-bar). There is no reference to the sub folder picker in the 1.9 Cheat Sheet, nothing under the Menu/Options button, nor the Task-bar pop-up menu, and I can't see a visible change in the user interface.
All I can find is the normal Ctrl+Q for folder selection. Am I missing something? Really grateful for any advice.
