    My 2c is that as long as there is an upgrade path, breaking backwards
    compatibility should be acceptable. Its certainly not ideal but if the
    pros outweigh the cons, why not.

    I think the problem comes when the product diverges too far from
    previous versions that upgrading becomes impossible.

    kind regards
