What's most interesting is that, even though the list of changes say  that all features are still the same, some features in the search designer are no longer there...

1. Ability to change the list field input type to be single-select or multi-select. (previously in WL9)

2. Ability to reset the list field back the same list as originally in the field definition ( however it is easily reset by removing and re-adding the field to the search form)

Just some thoughts...
