Important: #95384 - TCA internal_type=db optional for type=group
See forge#95384
Description
The TCA option
internal_ of TCA type
group defines which type
of record can be referenced. Valid values are
folder and
db.
Since
db is the most common use case, TYPO3 now uses this as default.
Extension authors can therefore remove the
internal_ option
from TCA type
group fields.
