Description

A rolling upgrade from 3.* to 4.0 (messaging version 11) unveils a regression caused by CASSANDRA-11128.

Generally, we store all possible options/attributes including the default values in the schema. This causes (expected) schema-version-mismatches during rolling upgrades and therefore we prevent schema pulls/pushes in this situation, which has been broken by CASSANDRA-11128.
