-----------------------------------------------

Not sure I understand the issue.

Could you please be more clear regarding what is broken, what the expected behaviour is, and
what is the behaviour you are observing?

> 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.
