When is Manual Identity Linking getting added to the JS SDK?

[Mortalife]

The docs and the most recently release week suggest that manual linking of identities should now be available:
https://supabase.com/blog/supabase-auth-identity-linking-hooks
https://supabase.com/docs/guides/auth/auth-identity-linking
https://supabase.com/docs/reference/javascript/auth-linkidentity

However, after updating to the most recently version of the sdk, it doesn't appear as if these functions are available (gotrue is about 50 versions behind), do we have any idea when these functions will become available?
