Andrus Adamchik closed CAY-1210.
--------------------------------

    Resolution: Fixed

Both 3.1 and 3.2 support 'cayenne.runtime.db.collation.assume.ci'. It was 
committed on Sept 14, 2011, i.e. after the patches. So I added it ti old 
release notes, and now closing the issue. If there's anything else we need to 
do, let's jira it separately.

> When performing a case insensitive search Cayenne spits out SQL which looks 
> like this
> SELECT .... WHERE upper(name) LIKE upper("fred")
> This prevents any index being used for the search. Since mysql already 
> performed case insensitive searches on text fields we need to suppress the 
> 'upper' functions being used in these situations. All searches on these 
> fields are already case insensitive.
