    [Fixed]

    - Fixed bugs in or_equals and dor_equals. (GH #8)

0.011     2017-03-03 22:35:34-05:00 America/New_York (TRIAL RELEASE)

    [Fixed]

    - Fixed bug iterating a tied hash and clearing the underlying hash
      of data.

    - Fixed bug in merge() where order of new pairs was reversed.

0.010     2016-02-01 19:02:50-05:00 America/New_York

    [Fixed]

    - pop() and shift() now return empty list when hash is empty instead of
      warning and returning undef values.

    - push() and unshift() of existing keys would cause corruption in
      certain cases involving optimized deletion of the existing key.  This
      has been fixed.

    [Documented]

    - Noted that pop() and shift() return just the value in scalar context
      and undef key/value if the ordered hash is empty.

0.009     2015-05-05 12:14:04-04:00 America/New_York

    [Fixed]

    - Fixed bug in new() that mishandled duplicate keys

0.008     2015-05-05 06:26:42-04:00 America/New_York

    [Optimized]

    - Methods which take lists of keys or key/value pairs no longer makes a
      temporary copy, which speeds them up substantially for large lists

0.007     2015-05-04 10:57:31-04:00 America/New_York

    [Optimized]

    - The 'as_list' method no longer makes a temporary copy of keys to list

0.006     2015-05-03 20:48:41-04:00 America/New_York

    [Changed]

    - The 'values' method in scalar context now returns an optimized
      count of elements.

    [Documentation]

    - Amended various parts of the documentation.

    - Fixed formatting of benchmark results and a SEE ALSO list.

0.005     2015-05-01 04:59:00-04:00 America/New_York (TRIAL RELEASE)

    [Added]

    - Added 'preinc', 'postinc', 'predec', 'postdec', 'add', 'subtract',
      'concat', 'or_equals' and 'dor_equals' functions for efficient
      in-place modification of hash elements.

    [Changed]

    - The 'keys' method in scalar context now returns an optimized
      count of keys.

    [Fixed]

    - Keys in the internal ordered list of keys are now stringified so
      they are in exactly the same form as they would be in a Perl hash.
      This slows construction slightly, but is necessary for correctness.

    - Added explicit stringification and numification overloads to mimic an
      unoverloaded object rather than falling back on the result of
      boolification.

    [Optimized]

    - Added indexed tombstone deletion for hashes over 25 elements; this
      makes deletion faster than all other pure-Perl ordered hash
      implementations that I benchmarked.

    - Numerous functions micro-optimized, including get and set.

    [Optimized]

    - Replaced use of List::Util::first to speed up element removal.
