I agree I was puzzled bout it. I believe it is because it's an major upgrade 
which is done in init() before the user backends are created and which also

| uid_owner | uid_shared_with | source                                                        
| target                                   | permissions |
| nata      | public          | /path/to/shared/folder | 
4d24e8c45f5f198f628a34547b1176e4f223497a |           0 |
| arthur    | public          | /path/to/shared/folder | 
4d24e8c45f5f198f628a34547b1176e4f223497a |           0 |

4d24e8c45f5f198f628a34547b1176e4f223497a |           0 |
(here one row is already doubled, because in 4.0.7  the link was not  shown in 
the GUI for me – so i clicked it again)

In the new share table however i do not see any shares of the item type "link" 
or similar. How are they stored?

However, the new link looks like 

the old link was:
