=item B<(*) (!) Reworked deltas>

Much of the delta code was reworked.

The constraint that a day is treated as 24 hours was removed (by
adding the concept of semi-exact deltas) to better handle daylight
saving time calculations.

Made cosmetic changes to which signs will be included in a delta to
make the deltas more readable.  Signs which are the same as the next
higher field will be omitted, even if they cross set boundaries.

Added support for non-normalized deltas.  See the $no_normalize
option for the parse and set methods.

Removed limitations on subtract=2 not working with business
calculations.

Thanks to discussion on perlmonks, and RT 65774 that prompted me to do
this.  I'd been wanting to do it for some time, but the discussion on
perlmonks made me realize that this needed to be much higher priority.

=item B<(!) Modified Delta_Format>

=item Time zone fixes

Newest zoneinfo data (tzdata 2011n).  RT 71595

Corrects a bug where +0000 and -0000 offsets were not parsed correctly.
Aaron Hall

The zoneinfo data includes rules more than 20 years in the future, so we
now store 30 years of future dates instead of 20 to catch these rules.

When parsing the timezone portion of the date, timezone abbreviations
now take higher precedence than zone names (since that is how timezone
information is typically specified).  That only impacts dates where
the a timezone name is the same as an abbreviation, such as 'CET'.

Previously, a date with CET in it was interpreted as in the CET timezone.
Now it is interpreted as in a timezone with the CET abbreviation.

=item Better handling of undef in DM6

The date/delta parsing routines in DM6 will now handle an undef argument
without issuing a warning.  Earl C. Ruby III

=item Bug fixes

Fixed a bug with the parse_format %f and %i formats.  Tommi Rintala

Fixed a bug where the Date::Manip::Delta::set function didn't work
to set the month value.

Fixed a bug where parsing some dates near during a DST change failed.

Minor bug fix when using Delta_Format.  Prompted while investigating
RT 41095.
