Date-Manip 6.52

on Perl CPAN

Added date ranges on unmodified dates in Recur
The date range can now be specified for either the fully modified
dates, or the unmodified dates. This will make it easier to work
with holidays in some instances. Based on
http://perlmonks.org/?node_id=1148735.

Added IWn and NWn recurrence modifiers
Based on http://perlmonks.org/?node_id=1148735.

(!) Reworked holidays slightly
Previously, every line in the Holidays section defined a unique
holiday. Now, the names determine the list of holidays.

It is not allowed to have two separate holidays named exactly the
same. It IS allowed to have complex holidays that require two (or
more) lines in the Holidays section to define them completely.

Based on http://perlmonks.org/?node_id=1148735.

Bug fixes
Fixed a bug where the RecurRange config variable wasn't getting
used.

Fixed a bug where some deltas were not parsed correctly as dates.
