Release Highlight

Boolean options only accept 'true' or 'false' in connection strings

Prior to this change, we accepted the values '1', 'y', 'yes', 't' as synonyms for true and '-1', '0', 'f', 'n', 'no' as synonyms for false. These have now been removed in an effort to make working with connection string options simpler.
