Browsers not supported after upgrade to 6.0.18

[godzone]

We have been running 6.0.16 on CentOS 7 and use Chrome primarily, last night I upgraded to 6.0.18 and I can't login anymore I get a message saying that my browser is too old. I tried Firefox, Safari and Chrome and still get the same message. I have downgraded back to 6.0.16 and access is back to normal.

Is this a bug in 6.0.18 or is there a setting I need to change in the configs ? I didn't see anything relating to old browsers (none of which I tried are old, they are all the latest versions) in the Release notes.

Thanks.
