TYPO3 Core

For example the following message is not helpful:

Changed showitem string of TCA table "<TABLE>" type "0" due to changed field "<FIELD_NAME>".

The message does not tell what the solution is or what has changed.

A much better message is this one:

Migrated TCA table "sys_dmail" showitem field of type "2": Moved additional palette with name "1" as 3rd argument of field "scheduled" to an own palette. The result of this part is: "scheduled, --palette--;;1"

Please check all messages of the TCA Migration class regarding the information content and adjust where it make sense.
