Huntsman Tournament Edition - Firmware?

I've been suffering from ghosting keys with my Razer Huntsman Tournament Edition and found users recommending updating the firmware. Where can I find the latest firmware for the Huntsman Tournament Edition? I've only found firmware for other the Huntsman keyboards.

• Huntsman Elite Firmware
• Huntsman Firmware
• Huntsman Mini Firmware Guide

Here's what I could find on the Tournament Edition:

• Huntsman Tournament Edition Support (only common questions)
• Huntsman Tournament Edition Downloads (only master guides)

Is there a central location for firmware or just random support articles?
