L3 - Default
I have setup variable column exclusion setup in Optimize 2.7.0 or lower.
I upgrade to Optimize 3.0.0
I upgrade to Optimize 3.1.0
Previously excluded variable columns are shown again
They should be excluded as configured in 2.7.0
This was a side effect of
OPT-3356 and a missing migration of the "old" __ separator used to identify variable columns in the frontend to the format used in the backend :.
E.g. a former var__doubleVar was missed to get migrated to var:doubleVar for all existing report configurations. We can recover the config in a 3.1.0 upgrade by performing that migration.
