Preliminary patch notes are up

[BreathlessTao]

they changed that due to not wanting congestion to effect the hinterlands, with the thousands of people afk

They don't want congestion, they should have the afk-kick permanently enabled. Can't wrap my head around why this game, struggling ever so much with network traffic/infrastructure/whatever, having a 15s-entire-inventory-backup in place, tolerates dozens, hundreds, thousands of people rooted to the same spot, not doing anything at all, for 2-5-8-10 hours. Completely insane.

I'm assuming the npc that lets you port outside will be removed

No need to assume this, it is in the patch notes. Well, doesn't say he will be outright removed, but...

[3.0] An aethernet has been added to Idyllshire.
* In accordance with this change, the goodly adventurer no longer transfers players to different locations.

...really not sure why Idyllshire needs aethernet though. I mean if we were to restore the aethernet network of the Hinterlands, and Idyllshire's would be tied to that - that would make sense. But Idyllshire itself? And mounts? ... Yeah, really not seeing the reason. It's far too small for all this.

...really not sure why Idyllshire needs aethernet though.

Because even now there's someone in Idyllshire asking where the NPC is. And most of the time they're asking for a half hour or more before someone finally tells them. They haven't said how big this aethernet will be. All we know they could have just put the exit warp on the aetheryte like it is every other city. Either way, this brings Idyllshire in line with the cities so there should be no confusion how to leave town from the aetheryte.
