Retirement tax questions

As 8915-F is available from the IRS and it's not much different of a process from the previous year, why is TurboTax several weeks behind on getting this added to the software? What's more, this form will likely cause some to owe money, and dragging out the release only hurts these who would like to get things taken care of. Maybe I'm ignorant to the situation, if so please enlighten me.
