 MASTER
 
+* Rails2.3 - Add coerced tests for true/false attributes in selects use SQL Server case statement. [Ken Collins]
+
 * Making sure that smalldatetime types are OK to use. Also fixed a bug in the #view_information method that 
   checks to see if a view definition is equal to 4000 chars, meaning that it is most likely truncated and 
   needs to use the backup method of sp_helptext to get it's view definition. [Ken Collins]
