Hi

 The latest available on cisco site is

Release Gibraltar-16.12.7 MD

If you intend to upgrade, read the release notes before:

"You cannot boot Cisco IOS XE Gibraltar 16.x.x, Cisco IOS XE Fuji 16.x.x, Cisco IOS XE Everest 16.x.x, or Cisco IOS XE Denali 16.x.x via TFTP for the first time with a Cisco IOS XE 3.x.xE boot loader. The Cisco IOS XE 3.x.xE boot loaders have a limitation, which prevents the booting of an image larger than 400MB via the TFTP server. Since Cisco IOS XE Gibraltar 16.x.x, Cisco IOS XE Fuji 16.x.x, Cisco IOS XE Everest 16.x.x, and Cisco IOS XE Denali 16.x.x images are larger than 400MB, you must boot the image via flash."

I strongly recommend staying with the latest 3.6.X or 3.7.X. 

Do not bother using 16.X.X if there is no way to monitor the control plane CPU & memory.
