What is the difference between firmware v1.0.85 and v1.1.12?

I was on the Download Center page for the TBS2603 H.264/H.265 HDMI encoder and noticed that the available firmware version is now v1.1.12. I am currently running v1.0.85 and would like to know if there is any reason to upgrade my TBS6903 if it is working well now. What has been changed/updated in the v1.1.12 firmware? Do you have a changelog or similar document explaining what has changed since version v1.0.85?
