Per today's changelog: The Metallurgy skill has been removed. All of its use cases are covered by both the Metalworking skill and the Mining skill (meaning a character with either one of these skills can perform smelting and metalcasting).
Character skill points will be automatically adjusted to refund any points spent on Metallurgy in the past.
