Does Yosemite support the old Mail view? All the screenshots I can find of Mail in Yosemite show the new Mail message view:

+--------------------+------------------------------------------------------------+
| Someone            | Guess what! Something happened. I don't know what is is,   |
| Something happened!| though. If I ever find out, I'll tell you.                 |
| Guess what! Some...|                                                            |

Whereas I like the old view:

+---------------------------------------------------------------------------------+
| From              | Subject                       | Date Recieved               |

| Someone           | Something happened!           | Recently                    |
| Someone else      | Guess what                    | Less recently               |
| Et cetera         | You get the idea              | Even less recently          |
|                   |                               |                             |
|                   |                               |                             |
|                   |                               |                             |
|                   |                               |                             |

In previous versions of Mac OS, I could change to the old view. Can I do so now?
Yes it does, just open Mail.app, then open the Preferences window from the menu bar. Select the Viewing tab and then choose "Use Classic Layout". I've tested this with OS X Yosemite. Here is a screenshot:
