Three major things:
There's a new poll available in-game - asking you, basically, whether you'd like Mythic to combine some, none, or all of the PvE zones on the clustered servers.
Mythic has introduced the plan for RvR missions
. Highlights include three different mission types (solo, group, or realm), multiple possible tasks per type, and 1750 unique missions available. They're also introducing caravans as targets and the ability to raze a tower (which will remove LOS/movement restrictions you normally have even with a broken tower). Finally, as rewards for these missions, you will receive gold, experience, realm points, and perhaps even titles.
And since a system like that needs a patch, we get the 1.75 patch notes
. Mythic's made some interface improvements (like tooltips, a better organized/more informative stats page, and multiple quickbars) - they're not quite to the level WoW is at, but progress is good. There are some class changes, including a Warlock nerf. And there's a strange note that monsters in homeland zones have increased in strength...
