	* iCalRecurrenceCalculator.m ([iCalRecurrenceCalculator
	+recurrenceRangesWithinCalendarDateRange:_rfirstInstanceCalendarDateRange:_firrecurrenceRules:_rRulesexceptionRules:_exRulesexceptionDates:_exDates]):
	when removing dates, the decremental count of dates to remove was

2008-03-10  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	* iCalTimeZonePeriod.m ([iCalTimeZonePeriod
	-dayOfWeekFromRruleDay:day]): the algorithm would never work if
	the day was monday. After it was changed for sunday (see below),
	it would return 1 instead of 0.

	-weekDayFromICalRepresentation:_day]): issue an error whenever the
	day cannot be deduced. Accept days notated with a prefix.
	([iCalRecurrenceRule -byDayMask]): don't strip the represented
	day, feed it directly to weekDayFromICalRepresentation: since it

	-recurrenceRangesWithinCalendarDateRange:]): make use of <<
	instead of exp2 to compute the mask.

2008-01-22  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	escaped instances of the separator passed as parameter.

2007-12-12  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	* iCalTimeZone.m ([iCalTimeZone -periodForDate:date]): at least

2007-07-10  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	* iCalToDo.m ([iCalToDo -setDue:newDueDate]): use setDateTime:

2007-07-03  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	* iCalRecurrenceRule.m ([iCalRecurrenceRule
	+recurrenceRuleWithICalRepresentation:_iCalRep]): the
	representation is generally a series of values separated by a ";".
	Therefore we need to split those values and feed them one by one.

	-1 instead of raising an exception if the week day could not be
	recognized.

	new method that parses the "CLASS" element of the card and returns
	an enum value.

	simplified method by initializing and returning folderString
	unconditionnally. If length < 76, the original string is appended
	to it.

	[self elementWithTag:].
	([CardGroup +groupWithTag:aTagchildren:someChildren]): same as

2007-02-08  Wolfgang Sourdeau  <wsourdeau@inverse.ca>

	* CardElement.m ([CardElement -namedValue:aValueName]): use
	NSString's rangeOfString instead of indexOfString for

2005-02-28  Marcus Mueller  <znek@mulle-kybernetik.com>

	* v4.5.47

	* iCalRepeatableEntityObject.m:  shifted code to
	  iCalRecurrenceCalculator

	* iCalRecurrenceCalculator.[hm]: new class method to calculate
	  complex recurrences. In SOGo this information is stored in quick
	  fields to reduce the complexity of lookups, hence we need to offer
	  a proper API to calculate date ranges from this information.
	  Fixed all calculations to explicitly set timeZone for all newly
	  created startDates - it seems the timeZone information is not
	  properly retained by the hour:minute:second: method from NGExtensions
	  which lead to improper DST related shifts.

	* NSCalendarDate+ICal.[hm]: new convenience constructor for calendar
	  dates from iCal representations (uses iCalDateHolder internally)

	* iCalEntityObject.[hm]: added convenience API

	* iCalRepeatableEntityObject.[hm]: added convenience API

	* iCalRecurrenceRule.m: bugfixes in -byDayList and
	  -iCalRepresentationForWeekDay:

	* iCalRecurrenceCalculator.m: implemented 'BYDAY' calculations for
	  weekly frequency. Note that 'COUNT' is still broken for this case.

	* iCalRenderer.m: updated rendering, now can render recurrence rules
	  and accompanied stuff properly.

2005-02-15  Marcus Mueller  <znek@mulle-kybernetik.com>

	* v4.5.43

	* iCalRecurrenceRule.[hm]: exposed some more of the API

	* iCalRecurrenceCalculator.m: some bugfixes. Split the code and gave
	  iCalWeeklyRecurrenceCalculator its own calculation - there are a
	  number of foreseeable differences to daily calculation that make
	  this necessary in the near future anyways.

	* v4.5.42

	* iCalRepeatableEntityObject.[hm]: added ability to properly calculate
	  the recurrence ranges within a specific calendar date range, taking
	  all possible exceptions into account.

	* iCalEvent.[hm]: convenience wrapper for the new method found in
	  iCalRepeatableEntityObject.

2005-02-14  Helge Hess  <helge.hess@opengroupware.org>

	* v4.5.41

	  header

2005-02-12  Marcus Mueller  <znek@mulle-kybernetik.com>

	* v4.5.40

	* iCalRecurrenceCalculator.[hm]: implemented all required (and simple)
	  calculations. Added some convenience API to query some of the more
	  obvious ranges suitable as limits for fetching/comparison. 

	* iCalRepeatableEntityObject.[hm]: new method for calculating the
	  last possible recurrence start date. This can be used for fetches
	  as well.

	* iCalEvent.[hm]: more convenient wrapper for the new method found in
	  iCalRepeatableEntityObject.

	* NSCalendarDate+ICal.[hm]: convenience methods for calculating
	  "distances" between dates.

	* tests/*: updated

	  as possible to RFC2445. Please note that this is work in progress
	  and far from being complete, yet.

	* iCalRecurrenceCalculator.[hm]: a controller implementing RFC2445
	  to properly generate recurrence ranges and accompanied functionality.

	* iCalEvent.[hm], iCalToDo.[hm]: now subclasses from
	  iCalRepeatableEntityObject, thus removed code dealing with
	  recurrences

	* NGiCal.h: added new headers

	* NGiCal.xmap: changed recurrenceRule mappings due to model change

	* tests/*: contains unit tests for stuff dealing with recurrences. See
	  accompanied README for details

2004-12-17  Marcus Mueller  <znek@mulle-kybernetik.com>

	* iCalPerson.[hm]: formalized participationStatus according to RFC2445.
