SB6121 Firmware Version

I'm trying to find out if my SB6121 cable modem has the latest firmware installed. I would appreciate it if anyone with this modem could check their firmware version and let me know what it is.  Mine says: Model Name: SB6121, Vendor Name: Motorola, Firmware Name: SB_KOMODO-1.0.6.16-SCM00-NOSH, Boot Version: PSPU-Boot(25CLK) 1.0.12.18m3,  Hardware Version: 5.0, Serial Number: 359079336146223301012019, Firmware Build Time: Feb 16 2016 11:28:04q.

Thanks in advance.

I have the same modem and firmware edition.  I own my modem too.

Apparently Comcast does not update frimware on customer owned devices, not a good practice.

I also got a call today about having to upgrade my modem.

I'd like to update the firmware first before shelling out money on a new modem.

Comcast does automatically update the firmware on all approved modems connected to their network pushed through from the CMTS.

cpfenn, are you moving to a higher speed? That's the only reason I know of that Comcast would want you to upgrade. As far as I know, the SB6121 is still an approved modem.
