FYI, still there in 6.3:

┌────────────────────────────────────────────────────────────────────┐
│ Sage Version 6.3, Release Date: 2014-08-10                         │
│ Type "notebook()" for the browser-based notebook interface.        │
│ Type "help()" for help.                                            │
└────────────────────────────────────────────────────────────────────┘

Please wait while the Sage Notebook server starts...
The notebook files are stored in: sage_notebook.sagenb
