[TYPO3-mvc] [!!!] FYI: Changes of Extbase in TYPO3 beta3

[Jochen Rau]

Hi.

This is the reference index of TYPO3 introduced in 4.2.0.

In the List-Module there is a cloumn [Ref.] showing the number of 
references of the list item. Click on the number to get more information 
about the references.

Sometimes it is useful (for extension developers) to kepp this index 
updated. But Sebastian and I think that it should not be set by default.

Regards
Jochen
