[1.6.7] - 2009-04-22

BREAKING CHANGE

In previous versions of PHPExcel up to and including 1.6.6, when a cell had a date-like number format code, it was possible to enter a date directly using an integer PHP-time without converting to Excel date format. Starting with PHPExcel 1.6.7 this is no longer supported. Refer to the developer documentation for more information on entering dates into a cell.
