although this is not very logical I run into the following problem. In Liquibase 1.9.x it is possible to specify a new boolean column with a default numeric value. With the current RC of the coming 2.0 this is not possible anymore. Because I have this in some older change logs here is a patch to BooleanType which also parses numeric values. 1 becomes true, everything else false. If you agree to this, can you include it?
