@Singleton
public class R6079XWIKI1878DataMigration
extends AbstractHibernateDataMigration

Migration for XWIKI1878: Fix xwikircs table isdiff data not matching RCS state of some revisions (when the state says "full" the isdiff column in the database should be false). Note: This data migration should only be executed if the R4359XWIKI1459 one has already been executed (i.e. if the database is in version >= 4360). This is because it fixes a bug in R4359XWIKI1459 which has now been fixed.
