Custom Fields (Optional Feature)
Custom Fields can be defined for events; you can specify any number of data fields for all events in a calendar. Each field has an associated input type, used when adding new events: single-line text, multi-line text, pulldown menu, multiple-choice list, or checkbox. You can specify the options for the pulldown menus and multiple-choice lists, as well as defaults for each field.

Event Templates
Customization using simple templates is available for the custom field section of the Event Entry Form, Event Popup Windows, Event Mail Messages, the "Details" column in List View, and in RSS feeds.

RSS Feeds
Calendars can supply RSS feeds; RSS (0.9, 0.91, 1.0, 2.0), and Atom formats are supported. You can the specify number of days in advance to include events for, and can filter by category and/or text.

iCalendar Publish
You can publish from an iCalendar-compatible calendar to a Calcium calendar. This means that you can - for example - automatically send events from an Apple OS X iCal calendar on your desktop to a Calcium web calendar.

iCalendar Subscription auto-refresh
You can now set subscriptions to external iCalendar files to automatically refresh. As in previous versions, you can set your Calcium calendar to automatically include events from remote external calendars; and you can subscribe to a Calcium calendar from an external calendar.

Open Time Slot Searching
You can search for an open time slot in any or all calendars.

Event Duration limits
A calendar can be set to require minimum or maximum duration for events.

No Last Minute Changes
A calendar can be set to not allow users to modify events within a certain time of their occurrence.

More Customizable Event Privacy
You can set a calendar so that Event Details are hidden from unprivileged users. Also, Event 'Privacy' settings can now apply in the same calendar, instead of only when events are included into another calendar. This means you can specify that an event should only be viewable by the person who created it.

Double-click to add
You can double-click to add a new event in a popup window. (Click in date headers in the Block View, in the date or day or blank cells in the List View.)

Quick Filter by Category
A Category Filter can be displayed in your calendar's header or footer; this lets user click on event categories to toggle displaying events in that category.

Other Features

• Option to display "Are you sure?" confirmation when deleting events. Can do it for all events, or just repeating ones.
• It's now possible to have all days in the Block View the same height; if there are too many events to fit in a day, vertical scrollbars can be displayed instead of making the cells taller.

Bug Fixes

• When exporting events, use calendar sort settings to determine listing order for events in day
• Fixed tab order problems on Event Edit Form
• When displaying Search or Filter text at top of results page, escape any HTML in the text
• When importing iCalendar or Outlook, event border is set from calendar's default setting
• Font sizes specified in ems; fixes problems w/different browsers inconsistent interpretations of named sizes in CSS
• Fiscal Views now show correct week numbers for Fiscal Year, not calendar year
• If bad date passed, stop after displaying the "Bad Date" message; don't attempt to display calendar for bad dates. (Could result in lots of messages in error log.)
• When adding event, if no primary category specified, but one or more "More Categories" are, instead of having no categories, use first "More" as the primary.
