iCalendar 0.11 (2005-11-08)
- Changed component .from_string to use types_factory instead of
hardcoding entries to 'inline'
- Changed UTC tzinfo to a singleton so the same one is used everywhere
- Made the parser more strict by using regular expressions for key
name, param name and quoted/unquoted safe char as per the RFC
- Added some tests from the schooltool icalendar parser for better
coverage
- Be more forgiving on the regex for folding lines
- Allow for multiple top-level components on .from_string
- Fix vWeekdays, wasn't accepting relative param (eg: -3SA vs -SA)
- vDDDTypes didn't accept negative period (eg: -P30M)
- 'N' is also acceptable as newline on content lines, per RFC
