- Deprecate legacy $rs->search( %condition ) syntax
- NULL is now supplied unquoted to all debug-objects, in order to
differentiate between a real NULL and the string 'NULL'
+ - New search() condition operator -value used to pass complex bind
+ values to DBI: search({ array_col => { -value => [1,2,3] }})
- +columns now behaves just like columns by not stripping a
fully-qualified 'as' spec (i.e. foo.bar results in $obj->foo->bar)
