For only items that were changed in patch 3.0.0 or later, see List of unique items changed after 3.0.0.
For only items that were changed prior to patch 3.0.0, see List of unique items changed before 3.0.0.
Due to table limitations, the above tables are limited to items changed in those periods, but show all changes made to items. I.E. if an item was changed in 2.4.0 and 3.6.0, then it will appear in both lists and both tables will show both versions.
