June 13, 2017 is the last release that is source parity with Firefox.
After that, T4Fx will only be matching feature parity.
It's been a long while coming, but it's here now.
Note that this does not mean T4Fx is being abandoned, just that Cameron Kaiser will no longer be matching Firefox's source code. But it is a first step to our final PowerPC obsolesence.
