Pre-release snapshot of 4.3
    
    This is intended to be a bug fix release which is expected to be released
    in December.
    
    There are some code infrastructure changes, which I belive to be in
    preparation for a later feature release (4.4) that might happen in about
    6 months (which could easily change).
    
    There are lots of fixes for better handling of bad data, only two of
    which have been backported into Fedora's 4.2 packages.
