• Reorganization of distribution to a more standard layout
  
• Migration to Module::Build with EU::MM backwards compatibility
  
• Migration of all tests to use Test::More and Test::Exception
  
• Added Devel::Cover report to DBM::Deep POD
  
  • Test coverage improved to 89.6% (and climbing)
    
• The following methods have been renamed to reflect their private nature:
  
  • init() is now _init()
    
  • open() is now _open()
    
  • close() is now _close()
    
  • load_tag() is now _load_tag()
    
  • index_lookup() is now _index_lookup()
    
  • add_bucket() is now _add_bucket()
    
  • get_bucket_value() is now _get_bucket_value()
    
  • delete_bucket() is now _delete_bucket()
    
  • bucket_exists() is now _bucket_exists()
    
  • find_bucket_list() is now _find_bucket_list()
    
  • traverse_index() is now _traverse_index()
    
  • get_next_key() is now _get_next_key()
    
  • copy_node() is now _copy_node()
    
  • throw_error() is now _throw_error()
    
• The various tied classes have been broken out. This means that testing
  "ref( $obj ) eq 'DBM::Deep'" will now fail. The correct test is
  "eval { $obj->isa( 'DBM::Deep' ) }".
  
• The various methods like push and delete now have the same return values as
  the standard builtins.
  
• TIEARRAY and TIEHASH now check their parameters more thoroughly
  
• Negative indices for arrays works as expected, including throwing the appropriate
  errors.
  
• RT #16877 is fixed (DBM::Deep broken with Perl 5.9.3+).
  
• RT #14893 is fixed (tie() and new() use different parameter lists).
  
• A bug with optimize and threading is fixed.
  
• autobless has received some attention, resulting in a number of bugs fixed.
  
• Removed mode option as it just caused confusion.
  
• Removed volatile option as it is pretty useless (use locking instead)
  
• Locking now implicitly enables autoflush
