It may be a good to mention that Inferno was removed as a skill.
It might also be helpful to mention if skills have changed positions on the skill tree. For example, Blaze moved up to Inferno's old position.
Would it be useful to include any item changes that included or now include added/removed skills? The Leaf Runeword used to add +3 Inferno, but that skill no longer exists; the staff now gets +3 Blaze instead.
