ri\_cal version 0.5.3 has been released!

- [http://ri-cal.rubyforge.org/](http://ri-cal.rubyforge.org/)
- 

A new Ruby implementation of RFC2445 iCalendar.

The existing Ruby iCalendar libraries (e.g. icalendar, vpim) provide  
for parsing and generating icalendar files,  
but do not support important things like enumerating occurrences of  
repeating events.

This is a clean-slate implementation of RFC2445.

A Google group for discussion of this library has been set up  
[http://groups.google.com/group/rical\_gem](http://groups.google.com/group/rical_gem)

enumeration

### 0.0.8

EXDATE and RDATE now pick up the timezone from DateTime, Time, and  
TimeWithZone values

http://rick\_denatale.lighthouseapp.com/projects/30941/tickets/2  
Missing arithmetic methods in PropertyValue::Date
- Fixed  
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

- Fixed 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

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

### 0.0.4

- Fixed 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
