A lot of information, a bit too much if you ask me but there is are quite some changes.

I might have missed some pointers but here are some if you cba to read up.
Revs rework that will hopefully bring some group pking back.
Loot keys to loot kills.
Defence requirement removed from God Dhide vambs and chaps.
Adjustments to Xerician Robes and Dragonhide, also Dinhs Bulwark changes.
Some changes for luring and skulltricking.
Single-plus areas; this means that PvP will always take priority, so if a player is in a fight with a monster, they can be attacked by another player. In all other aspects, the old single-way combat mechanics would still apply.
PJ timer; this will mean that players have a grace period in which they cannot be attacked by other players if they’re still fresh from an encounter.
There is more information in there; if interested the link can be found above.
What do you think about these "changes"?
