 ## Extensions in the latest SNAPSHOT version 1.3
 
+* introduced dotted multipart names for uservariables (issue #608)
 * changed behaviour of dotted multipart names for tables and columns to accept ORM class names (issue #163)
 ** the parser allows now empty inner names, to still accept missing schema names for SQLServer (db..col)
 ** methods like **getDatabase** will still work but have no sense using it for classnames
