Changing version to '26'.

Comment 4 Giulio 'juliuxpigface' 2017-04-27 18:23:44 UTC
Proposing as a FE for Fedora 26 Final.

The SELinux' denial is caught after the boot of the live environment.

It's not strictly a blocker, since no notifications pop up and so it doesn't violate the "2.5.4 SELinux and crash notifications" Final criterion.

Howewer, in my opinion, it might be a "bad presentation" for the new release, if not fixed in time.
