0.16 2005-05-12
- fix 'BYWEEK' -> 'BYWEEKNO'
- Depends on DateTime 0.27 because it uses local_rd_values(). This fixes a local/UTC problem reported by Dave Rolsky. - uses no DateTime.pm internals
- removed (undocumented) arguments 'after' and 'start'

0.15_02 2005-01-27
- allows interleaved neg/positive values; allows repeated indexes. Supports weird argument lists such as [ -200, -10, -10, 200, 20 ]. Speed is slower by another 10%.

0.15_01 2005-01-26
- full overflow checking.
The previous version only checked for some kinds of month overflows. The tests run slower by about 12%.
- checks for invalid parameters, such as "monthly( months=>xx )" or "yearly( months=>xx, weeks=>xx )"
- added a dispatch table for "offset" calculations - fixed and added tests for monthly( week => ...) - modified "sort positive values first". Patch by Yitzchak Scott-Thoennes. - refactored setupparameters()
- Updated pod and tests.

0.15 2005-01-19
- array-ref parameter lists are not mutated. Patch by Daisuke Maki. - rewritten "sort positive values first" in setupparameters()

0.14
- requires DT::Set 0.17, because 0.16 had a bug that would break some tests.

0.13 2004-06-17
- a weekly recurrence with an interval behaves strangely, if the given dtstart is a sunday. Reported by Bridget Almas. Fix: _week() uses "week start day" in the calculation.

0.12 2004-05-26
- monthly recurrence at day 29 shows march-01. Reported by Bridget Almas.

0.11 2004-05-24
- using both 'interval' and 'start' parameters could cause the program to hang. Reported by Bridget Almas.

0.10 2004-03-17
0.0901 2004-03-09
- the recurrence functions accept infinite DateTimes, as required by DT::Set 0.1402

0.09 2003-10-10
- recurrences can be formatted using
DateTime::Format::ICal->format_recurrence(). Some recurrences (ex: nanoseconds) are not supported by ICal format. - added nanosecond tests

0.08 2003-10-31
- bugfix: when "interval==1" it should be processed as if there was no interval. Found by Danny Rappleyea - document "start" parameter.
- changed some operations in next/previous that were done twice.

0.07 2003-09-02
- tests pass under Perl 5.00503

0.06
- defines DateTime::Set::ICal class, in order to provide ICal strings to represent recurrences (set/get_ical)

0.05 2003-05-23
- memoizes durations; makes less calls to DT::Duration->new - 'weekly' can use 'week_start_day'

0.04 2003-05-14
- turn on warnings in tests and fix all warnings given. - require DateTime::Set 0.06

0.03 2003-05-12
- iterates using binary tree
- parameter checking
- fixed behaviour of negative numbers (rfc2445)

14h and -15min was: 13:45 = subtract 15 minutes

now: 14:45 = last 15 minutes of hour - removed parameter 'year_type'
- 'duration' argument is obsolete
- added 'interval' parameter
- moved local parameters to a hash
- moved unit-specific subs to hash
- added year_type => 'weekly' to yearly (internal) default is year_type => 'monthly'.

0.02 2003-04-27
- tests month-day overflow for positive day offsets, if 'month' argument is specified. Skips a datetime if it is invalid. - setup structure to allow other overflow tests. - returns empty set for 'impossible' recurrences. - many docs and code tweaks. by Dave Rolsky

0.01 2003-04-21
- CPAN upload
- no longer inherits DateTime::Set

0.00_11

• added 'set' tests
• docs correction. Dave Rolsky

0.00_10

• ISA DateTime::Set
• removed as_set
• moved all accessors to DateTime::Set
• requires DT::Set 0.02

0.00_09

• new syntax $r = DT::E::R->monthly (

  days => [ 4, 15, 18 ], hours => [ 10, 20 ] );

0.00_08

• both previous and next work; all tests pass; more docs

0.00_07

• works with 2-D durations; looks up table in linear time (in worst case). That is, a 4x4 table gives 4^4 combinations but is looked up in 4*4 time. But it could be done in 4log4 time...

0.00_06

• works with multiple durations like $r = DT::E::R->monthly (

  duration => \@durations );

• durations must be pre-sorted.

0.00_05

• refactored constructor subs
• added a very rough multiple-duration structure (doesn't work with mixed negative/positive durations)

0.00_03

• "duration" argument in constructors

0.00_02

• previous, closest, weekly
