I mentioned earlier this week that Sugar 6.1.3 went out last week, and detailed one change in a configuration option for the time delay on quicksearches. There was one other change as well that will affect most users, which deals with using the enum fields on searchforms ( see Bug 41209 for more details ).
Previously, when you searched for a –blank-/empty value in a drop down field in a module, the search would return all results irrespective of this value. Now when you search for an empty value the search will return all records where field value is empty. Also note this affects any saved searches you may have, so you’ll want to double check them and fix them as well.
