It's still the same. In the 'Save as Type' dropdown in the Save As dialog, you can choose between three types of templates:
Excel Template (*.xltx) is the standard type for Excel 2007 and later.
If your workbook contains VBA code, you should select Excel Macro-Enabled Template (*.xltm).
The third type, Excel 97-2003 Template (*.xlt) is only for compatibility, if you have to support users who still have Excel 2003 or older.
