Ultima Online

Harvest and crafting of all kinds now require 0 skill investment. You can fish up sea serpents, craft golems, repair items, enhance with valorite, and stonecraft at 0.
Footwear removed from fishing tables with prejudice
Weapon abilities unlock at 50 and 70
Monster stealing available at 50 (very low chance)
Animal Lore no longer requires targets to be tamed before viewing their stats
Anatomy and Evaluating Intelligence now open the Animal Lore window upon success
Lockpicking and Remove Trap skills are no longer relevant. They will now choose a number between 0-80 and add 1/3 of the picker's Dex. If the result is higher than the lock level, success!
Cartography skill is no longer relevant. Treasure Maps may be read automatically. For purposes of chest quality and digging range, it has been replaced by Mining.
Corrected Ninjitsu skill requirement values from base ServUO to match in-game book and official website

Boats do not decay (hard to test, no promises)
Added a system message to fukiya and shurikens when you miss
Due to an unknown bug (treasure maps appear blank), treasure maps will send a system message with the sextant coordinates of the chest, similar to fishing

New Haven escorts' gold reward has been reduced.
All NPCs will teach skills up to 40, instead of just New Haven
Ore elementals (spawned from Gargoyles Pickaxe) now have a chance to drop a runic hammer
