Benjamin Lerer commented on CASSANDRA-10721:
--------------------------------------------

{quote}Moved the referencesUserType function to AbstractType. This is now 
effectively a refactoring of the (replaced) references function to specifically 
check the user-type's name.{quote}
I do not see the changes that you mentioned. In your {{10721-udt-alter-3.0}} 
branch. Did I miss something?

> CASSANDRA-10650 switched UDA's {{initcond}} serialisation in schema to its 
> CQL literal. This means that if any particular field is renamed in the UDT, 
> or of its type gets changes, we will not be able to parse initcond back.
> We should either:
> 1) Forbid renames and type switches in UDTs that are being used in UDAs, or
> 2) Make sure we alter the UDAs in schema alongside the new UDT at all times
