[hibernate-dev] Changing method signatures in micro releases

Hi, When updating Hibernate OGM to make use of ORM 4.3.5, I noticed a changed method signature in AbstractCollectionPersister (abstract method doProcessQueuedOps() has a new parameter). This causes a compilation failure in OGM, as we naturally still override the old signature. I can solve this particular case in a compatible manner by declaring both variants of the method in our sub-class (omitting the @Override annotation), but I'm wondering how we should generally deal with this kind of issue. Are micro-releases considered strictly backwards-compatible, so that e.g. all of ORM 4.3.x should be useable together with an integrator (such as OGM) known to work with 4.3.0? This would have been my assumption originally. Are there any rules for what kind of changes are to be expected by an ORM micro/minor/major update? Thanks, --Gunnar
