Types 3.4 includes a migration to a new database structure for storing post relationships, to improve how translations of related posts are handled.

If you use the Relationships API (e.g. the toolset_get_related_posts function) then you won't be affected, they will still work.

If you are writing custom SQL queries, you'll need to study the new database structure so that you can update them.

The relationships are now stored using a combination of the toolset_associations table and a new toolset_connected_elements table.

The associations table now records the connections indirectly, of the "elements" in the other table, which stores the IDs of the posts themselves.

If you use phpMyAdmin or a similar tool to inspect the tables you should be able to see the same, it is reasonably self-explanatory.

You'll need to study this to identify what needs changing in your custom SQL query, which is not something we can provide support for I'm afraid.
