Why 17.05 as numbering?
 
This release includes a critical security update which required moving to our current firmware numbering system. The updated 17.05 firmware is still based on the 2017 feature set.
The latest versions, such as 20.04, contain all the new features we have released in the last 3 years.

What are the noticeable features that are not part of 17.05?
  • 4 K UHD resolution support
  • New wacom tablets, local termination (everything added after firmware 5.5)  
  • AWS session type (no MFA, only connection via TAA) 
  • Reboot notification message 
  • Low light mode
Teradici recommends to always run a supported version to stay updated with the latest security updates. Updated support information for specific versions can be found on our Product Lifecycle page.

Firmware Support States:
