       - bug fix: custom prefix_re got reset in hash merge

       - bug fix: restore_config() didn't recreate DM::Config object
         but hash instead

0.17   2009-12-12

       - INCOMPATIBLE BEHAVIOUR CHANGE: SUBTRACT merge on two hashes
         is now defined as a NORMAL merge, except that all keys on the
         right-side hash which do not have a merge prefix will be
         assumed to have a DELETE prefix. This means the SUBTRACT mode
         can now grok mode prefix and options key too.

       - INCOMPATIBLE BEHAVIOUR CHANGE: merging hash keys with DELETE
         mode now will make the key disappear even if there is no
         corresponding left or right side. merge({}, {"!a"=>1}) and
         merge({"!a"=>1}, {}) used to be {"!a"=>1} but now will be
         {}. I believe this is more intuitive/expected.

       - new config; premerge_pair_filter

        - Minor fix to options key handling

0.13    2009-12-07

        This is a major refactoring of the module. The goal is to make
        the code more flexible (e.g. adding future modes, changing
        prefix for each mode, etc). Configuration is also
        significantly expanded.

        - rename dist: Data-PrefixMerge -> Data-ModeMerge (to reflect
          the fact that merging mode can be selected not only via a
          "prefix" but more generally by a regex test on key).

        - incompatible behaviour: all hash prefixes on the left-side
          and right-side hash will be removed recursively after merge,
          even if it is not a hash-hash merge, e.g. mode_merge({a=>1},
          {b=>{"+c"=>1}) used to become {a=>1, b=>{"+c"=>1}} but now
          it will become {a=>1, b=>{c=>1}}. this ensures that all
          prefixes are "cleaned" after merge.

        - incompatible behaviour: KEEP prefix (^) is now always sticky
          so it always protects future merges (equivalent to old
          config's preserve_keep_prefix). If you want KEEP prefix to
          be removed after merge, set config C<readd_prefix> to 0.

        - incompatible change: options key is now enabled by
          default, with "" (empty string) as the key.

        - incompatible change: configuration 'parse_hash_key_prefix'
          renamed to 'parse_prefix'.

        - removed: remove_keep_prefix(), replaced by the more generic
          remove_prefix().

        - configurable prefix for each merging mode.

        - new config: set_prefix allows you to change prefixes, even
          in the middle of recursive merge.

        - new config: allow_override & disallow_override.

        - new config: allow_create_array, allow_create_hash,
          allow_destroy_array, allow_destroy_hash.

        - new config: exclude_parse, exclude_parse_regex,
          include_parse, include_parse_regex.

        - new config: exclude_merge, exclude_merge_regex,
          include_merge, include_merge_regex.

        - new config: disable_modes. each merging mode can now be
          individually enabled/disabled through configuration.

        - options key now understands almost all configuration.

0.12    2009-11-25
        - new option: hash_options_key
        - fixed random ordering bug (closes #51799)

0.11    2009-11-23
        - add max_level parameter to remove_keep_prefixes()

0.10    2009-11-23
        - handle recursion in remove_keep_prefixes()

0.09    2009-11-18
        - fix bug in remove_keep_prefixes()

0.08    2009-11-18
        - new method: remove_keep_prefixes()

0.07    2009-11-18
        - minor fixes

0.06    2009-11-08
        - INCOMPATIBLE CHANGE: getting and setting config is now done via
          $merger->config->confname instead of $merger->config->{confname} to
          catch config name typos at compile time.

0.05    2009-06-22
        - yet another incompatible change: keep prefix now uses '^' instead of
          '!' on the left side. this allows keep mode on the right side. on a
          series of merge we can now introduce keep mode at one point (not just
          on the first hash) and then preserve that keep mode afterwards.

0.04    2009-06-17
        - support KEEP merge for hash & hash

0.03    2009-06-12
        - incompatible change: '*' prefix on the left now means normal merge
          mode (to protect hash keys having special characters). keep mode now
          uses '!' on the left side.
        - add config: preserve_prefix (default is 0)

0.02    2009-03-30
        Rename Data-RecMerge to Data-PrefixMerge

0.01    2009-03-29
        First release
