The new 3.4.0 release of Liquibase expands offline support with a new “snapshot” parameter which can be passed to the offline url pointing to a saved database structure.  Posted 02 JUL 2015 by Nathan Voxland [1]

Good timing!  I was just trying to do a diff against a snapshot and hit an exception that the operation isn’t supported.  But lo and behold, they just released support for it.  Sometimes you’re lucky. :)  This will be very handy.

Laters,
