There seems to be some changes in account settings of the Gmail account with the new features including Google+. Of course the settings are much more related to and aligned with Google+. And some options available previously seems to be gone. I'm not sure whether they will later appear in a different form. But as of now there's a link for the old settings page in bottom of the new settings page saying "Looking for older account options and your Google Products?" which brings the same old "settings page". (Note: Of course there are other ways to access these pages by the means of direct URLs etc...)
This might be useful specially if you used to access different products like blogger, App Engine from within your Google account settings.
