Added Update Service to Calendar that automatically checks for updates and notifies you in the control panel.
Added 'calendar:event_first_date_timestamp', 'calendar:event_last_date_timestamp', 'calendar:event_first_date_timestamp_utc' and 'calendar:event_last_date_timestamp_utc' variables to Calendar:Events tag and custom field display in Channel:Entries. The former of the two versions are a localized adjustment to the timestamp so you can compare it correctly with EE's 'current_time' variable, etc.
Added 'calendar:event_is_past', 'calendar:event_is_current', and 'calendar:event_is_future' conditionals for Calendar:Events tag.
Added 'calendar:event_start_date_timestamp', 'calendar:event_end_date_timestamp', 'calendar:event_start_date_timestamp_utc' and 'calendar:event_end_date_timestamp_utc' variables to Calendar:Events tag and custom field display in Channel:Entries. The former of the two versions are a localized adjustment to the timestamp so you can compare it correctly with EE's 'current_time' variable, etc.
Fixed a bug where unknown timezones could cause errors in Calendar control panel and template tags. Now defaults to UTC.
Fixed a bug where filtering by 'not' category ID and using 'uncategorized_entries' parameter would kill all other parameter filtering for the template tag.
Fixed a bug where 'CURRENT_USER' option did not work in the author_id="" parameter of Calendar tags.
Fixed a bug where date_range_start="today" and date_range_end="today" parameters in Calendar:Events tag would not correctly show all events for that given day.
Fixed a bug where the {if current_day/week/month/year} conditionals were not correctly localized to the users preferences.
Fixed a bug where the default EE datepicker language file would not load when Calendar is installed because it is also named 'calendar'.
Fixed a bug where submitting invalid date values into date_range_start="" and date_range_end="" parameters would trigger an error instead of failing gracefully. Will now default to 'today' when an incorrect value is passed.
Removed Calendar:Cal template tag in favor of Calendar:Events and using the functionality broken down into Calendar:Month, Calendar:Week, and Calendar:Day template tags. Removed the hidden auto-formatting functionality from these template tags as well.
Removed {rules}{/rules} variable pair and variables from Calendar:Events template tag.
Removed ability to repeat events forever (must have a specified end date).
Removed show_RANGE="" parameters. This is generally already available with the easy-to-use text date formatting options for date_range_end="" parameter.
Removed ability to filter event results by time (full days allowed only now).
