Jehalapeno:
The major on paper change is that you can greet and talk to disfellowshipped people at the Kingdom Hall now.
Though there may be some latitude in what individual JWs might consider a suitable greeting at meetings, the official position allows only for briefly greeting and welcoming a removed person at the meeting, not extended conversation or socialising.

but has the cult relaxed the rules recently?
They have relaxed the rules slightly, but only in the context of people who want to return. The leadership still dictates that individuals who have been baptised, including minors, who express that they do not accept JW doctrines and/or authority (i.e. ‘apostates’) are still to be completely shunned.
