0.8.7

fix ticket #29-supress x-rical-tzsource when not relevant

0.8.6 - 15 April 2010

Fixes an issue of RFC 2445 non-conformance - change management time attributes (dtstamp, last_modified, and created) MUST be zulu time
Changed VTIMEZONE export from tz_info
   Discovered that RFC 2445 expects a timezone period onset to be local time before the change, while TZInfo gives it after the change
     Thanks to both Michael Hale and H. Wade Minter for reporting this.
   Changed from generating a single RDATE line for a timezone period with multiple values to multiple RDATE lines
     to fix a problem reported by Michael Hale.

0.8.5

Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/26
  events with date parameters failing

0.8.4 - 18 September 2009

Refactored load structure, should now be conforming to    
      http://weblog.rubyonrails.org/2009/9/1/gem-packaging-best-practices
  I did finesse the load path issue a bit as a workaround to RSpec not putting lib on $LOADPATH
  the lib directory will get added to load path IF IT ISN"T ALREADY THERE

Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/25
   please clean your code up to be quiet

 Thanks to Ryan for such a courteous problem report.

0.8.0 - 11 August 2009

Minor Version Bump - There is a small potentially breaking change see section on treatment of X-properties below

* Unknown Components

Starting with version 0.8.0 RiCal will parse calendars and components which contain nonstandard components.

For example, there was a short-lived proposal to extend RFC2445 with a new VVENUE component which would hold structured information about the location of an event.  This proposal was never accepted and was withdrawn, but there is icalendar data in the wild which contains VVENUE components.

Prior to version 0.8.0, RiCal would raise an exception if unknown component types were encountered.  Starting with version 0.8.0 RiCal will 'parse' such components and create instances of NonStandard component to represent them.  Since the actual format of unknown components is not known by RiCal, the NonStandard component will simply save the data lines between the BEGIN:xxx and END:xxx lines, (where xxx is the non-standard component name, e.g. VVENUE).  If the calendar is re-exported the original lines will be replayed.

* Change to treatment of X-properties

RFC2445 allows 'non-standard' or experimental properties which property-names beginning with X.  RiCal always supported parsing these.

The standard properties are specified as to how many times they can occur within a particular component.  For singly occurring properties RiCal returns a single property object, while for properties which can occur multiple times RiCal returns an array of property objects.

While implementing NonStandard properties, I realized that X-properties were being assumed to be singly occurring. But this isn't necessarily true.  So starting with 0.8.0 the X-properties are represented by an array of property objects.

THIS MAY BREAK SOME APPLICATIONS, but the adaptation should be easy.

0.7.7 - 6 August 2009

- No changes other than a version number bump.  github seems to have failed to notice the commit of v0.7.6
  and didn't build the gem.  Hopefully it will notice this one.

0.7.6 - 6 August 2009

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/20
  RiCal::PropertyValue::Period was returning a nil ruby value.

0.7.5 - 3 August 2009

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/19
   Microsoft ical exports double quote tzid values in parameters, which caused a failure to find VTIMEZONES
   This exposed an issue with parameter parsing.  Did the simplest thing which could work which was to
   strip the quotes.  Need to BOLO for other pathological cases showing up in future, which may require
   smarter parameter parsing.

0.7.4 - 21 July 2009

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/17
 Problem with Alarm trigger property value
- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/18
 Problem with exporting components with sub-components

0.7.3 - 13 July 2009

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/14
   component without recurrence properties should enumerate just itself only if it is within the period between starting and before
- added the :overlapping option to OccurrenceEnumerator#occurrences - Allows the enumeration of occurrences which are either partiall or completely within a timespan given by a pair of Dates/Times/DateTimes
- Fixes some Ruby 1.9 incompatibilities
- Added some new rake tasks to run specs under multi-ruby

0.6.1 - 6 June 2009

- Fixes problem with file which loads activesupport for the rake spec:with_activesupport task, it now
requires >=2.2 instead of <=2.2 - Thanks to Paul Scott-Murphy for finding this.

0.6.0 - 5 June 2009

Time for a minor version bump.
  - Improved overall enumeration performance bypassing most of the effects of the poor performance of Ruby's DateTime class.
  - Added a framework for performance monitoring during development.
  - New performance directory with subdirs for code to be monitored for performance (subjects)
  - New script files: 
       script/benchmark_subject runs a ruby benchmark on one performance subject
       script/profile_subject runs ruby-prof for a subject and puts a kcachegrind compatible calltree in the performance_data directory.
  - New rake tasks: 
       performance:benchmark runs benchmarks against all subjects in the performance directory and produces a consolidated output file in performance_data/benchmarks.out
       performance:profile runs script/profile_subject against all subjects in the performance directory.

0.5.3 - 1 June, 2009

- Improved performance of time zone enumeration, TimeZonePeriod now caches occurrences
- Added a profiling directory which contains ruby programs which benchmark and/or profile performance

0.5.2

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/6
 Type of dtstart and dtend (DATE or DATETIME) now preserved on enumeration

0.0.8

- Fixes http://rick_denatale.lighthouseapp.com/projects/30941-ri_cal/tickets/1
 EXDATE and RDATE now pick up the timezone from DateTime, Time, and TimeWithZone values

 Missing arithmetic methods in PropertyValue::Date
- Fixes http://rick_denatale.lighthouseapp.com/projects/30941/tickets/3
    Components with no recurrence rules or rdate properties failed on enumeration, they now
    will enumerate a single occurrence

0.0.7

- Fixes a bug relating to properly recognizing ActiveRecord::TimeWithZone
- DATETIME propertyvalues will now return an instance of TimeWithZone instead of DateTime when
activesupport is present, and it is appropriate. See the README for details

0.0.6

- Added rake tasks to run specs with either the tzinfo gem or activesupport (<=2.2)
- Default rake task now runs both of these

0.0.5

- Fixes a bug in occurrence enumeration reported by paulsm on github

0.0.4

- Fixes a bug in imported timezones reported by paulsm on github

0.0.3

- Added tzid method to Ruby Time and DateTime instances, and to ActiveRecord::TimeWithZone if it is defined this method is used to determine the desired

timezone when an instance of one of these classes is given as the value of a datetime property. If the tzid is nil then the default tzid is used, if it is set to :floating then the property will be a floating time.

- Removed the ability to pass an array with a tzid string and a date-time since the above made it unnecessary
- The ruby datetime property returned from the ruby_value method on the DateTime property will return an instance of ::DateTime with:
  -- The proper utc offset
  -- The tzid set to the right tzid
- Made exdate/rdate building possible
- Added a default_tzid attribute to the Calendar component, if this attribute is not set for a particular calendar it will delegate to the default set

for the DateTime property class.

- Added fix patches from
