Patch 2.3 introduced several changes to Tabetha's Farm. It has always been a home to Tabetha, a Neutral Human NPC, but from patch 2.3 has changed dramatically.

Patch 2.3 Changes

Firstly, it was given a name, as previously there was no distinction between the farm and the surrounding land. A paved road leading to the farm was added, as well as a marker on the map, where before there was nothing indicating it was there. The road goes past the farm and leads to Beezil's Wreck, which also received some attention in Patch 2.3.

Most significantly, 3 new NPCs have been added to Tabetha's Farm, Apprentice Morlann, Andello Porter and Apprentice Garion.
